High temperature heat pump dryers are mainly used in those areas 5

High-temperature heat pump dryers are mainly used in agriculture, tobacco, food, medicinal materials, and industry. The high-temperature heat pump refers to the heat pump whose heating outlet water temperature and air outlet temperature can reach more than 80 degrees, and the heat pump with the heating outlet water temperature of 65 degrees is called medium temperature heat pump or medium and high temperature heat pump.

Working principle: 1) Compression process: The refrigerant gas at low temperature and low pressure is compressed into gas at high temperature and high pressure by the compressor. At this time, the work done by the compressor is converted into the internal energy of the refrigerant gas, which increases the temperature and pressure, which is called the adiabatic process in thermodynamics.

2) Condensation process: The high-temperature and high-pressure refrigerant gas from the compressor flows through the condenser, and the wind or water is continuously released to the outside to condense into a medium-temperature and high-pressure refrigerant liquid. Liquefaction occurs when the temperature of the refrigerant decreases but the pressure does not change, which is thermodynamically called an isobaric process.

3) Throttling process: The medium-temperature and high-pressure refrigerant liquid coming out of the condenser becomes a low-temperature and low-pressure refrigerant liquid through the throttling device. In thermodynamics, it is called the isenthalpy process.

4) Evaporation process: The low-temperature and low-pressure refrigerant liquid from the throttling device flows through the evaporator, and continuously absorbs heat into the room with wind or water, and evaporates into low-temperature and low-pressure refrigerant gas. The absorbed heat becomes the latent heat of the refrigerant, and although the temperature does not rise much, the internal energy increases a lot.

Since the pressure does not change much, it is thermodynamically called an isobaric process.

There are several types of dryers, among which heat pump dryers are more common, and people have a high degree of acceptance of it, what is the principle of heat pump dryers? The speed and power consumption of the dryer are related to its power, and the greater the power, the more power will be consumed. So, how much power does a heat pump dryer generally have?

After the heat pump dryer compresses and decompresses the heat pump, after the heat is released, the heat in the air absorbs the moisture in the clothes in the closed space to achieve the effect of removing moisture, so that the clothes are slowly dried and the process transformation from wet clothes to dry clothes is realized.

After the clothes are used in the heat pump dryer, they appear fluffy and soft, and the drying is very uniform, and there will be no trembling on the surface and without drying on the back. Moreover, the method of low-temperature drying can effectively protect the clothes and avoid damage to the clothes. The energy consumption in the process of drying clothes is relatively low, and it will not consume too much electricity, which can effectively save costs for daily use.

But the ** of heat pump dryer is higher than that of condensing dryer.

The power of the heat pump dryer is 500-1000W, and its power will be different according to the difference of each heat pump dryer, such as Panasonic NH-9095T heat pump dryer with a power of 960W, Xiaomi Mijia.

The heat pump dryer has a power of 750W. When buying a heat pump dryer, you can use its manual to understand the specific power basis and other parameters.

Dryer in the direction of the development of vertical energy reduction, many people think that the dryer is too electricity-consuming, in fact, there are many kinds of heat sources used in the dryer, wood, natural gas, electricity, oil, excitation hood, etc., if you want to use electricity to dig lead, it is recommended to use a high-temperature heat pump dryer, this dryer is quite an electric heating pipe energy saving of more than 70%. The high-temperature heat pump dryer is mainly used for: mushrooms, clothing, grains, fertilizers, mosquito coils, fabrics, tobacco, leather, vegetable dehydration, medicines, pulverized coal, slime, lignite, sludge, wood, etc.

The energy efficiency of the machine is relatively high, safe and stable, economical and energy-saving. It is one-quarter to one-third of the drying energy consumption of ordinary electric boilers and oil-fired boilers.

Air energy heat pump dryers consume less energy and generate more energy-efficient heat that is constantly circulating. Generally speaking, the power of a 7 hp air energy heat pump dryer is as follows:

According to the drying temperature range, heat pump dryers can be divided into four types: low-temperature heat pumps, medium-temperature heat pumps, high-temperature heat pumps and ultra-high-temperature heat pumps.

1.Low-temperature heat pump: heat pump with a drying temperature between 10-45 degrees Celsius, that is, a heat pump whose drying temperature may be lower than the ambient temperature, in addition to being able to heat up and dry, may also need refrigeration and cooling, therefore, four-way valve switching is required, and the design of the working point is difficult and the structure is complex.

Due to the relatively low drying temperature of low-temperature heat pumps, the time is usually relatively long;

2.Medium temperature heat pump: refers to the heat pump with a drying temperature between 45-65 degrees Celsius, that is, the drying temperature is higher than the ambient temperature, the structure is simple, the accessories are mature, the cost is low and the efficiency is high.

The temperature range of 45-65 degrees Celsius is the best temperature for agricultural products, seafood and other foods, basically all agricultural products and seafood are suitable for drying in this temperature range, and the speed, quality and efficiency can be achieved at a high level. Therefore, as long as it is dry food, you should try to consider or try a medium temperature machine;

3.High-temperature heat pump: refers to the heat pump with a drying temperature between 65-85 degrees Celsius, with a simple structure, but the high-temperature accessories are expensive, and the drying efficiency cannot be closed to the medium-temperature heat pump.

High temperature has a great impact on the volatilization of water, and some agricultural products, seafood, and industrial products must have a certain high temperature in order to volatilize the bound water inside;

4.Ultra-high temperature heat pump: refers to a heat pump with a drying temperature between 85-105 degrees Celsius, with complex structure, expensive accessories and high efficiency.

Since UHT heat pumps require refrigerants with a high boiling point, they can only be used with closed-loop heat pumps. With a drying temperature close to 100 degrees Celsius, flash drying can be basically achieved, and the drying speed is very fast, but there are very few drying products of this type on the market at present.

According to the size of the drying capacity, the heat pump dryer can be divided into large, medium and small. Heat pump dryers can be divided into two categories: single heat source and dual heat source according to different working cycles and functions.

When the drying room needs to be heated and heated without dehumidification, if there is no steam or other auxiliary heat source, it is generally necessary to start the auxiliary electric heater, and the power consumption is higher.

The dual heat source heat pump dryer has two working cycles of dehumidification and heat pump, two evaporators of dehumidification evaporator and heat pump evaporator, and has two functions of drying chamber dehumidification and heating. When the drying chamber needs to be dehumidified, the dehumidification system works; When the drying chamber needs to be heated, the heat pump system can be started, and the refrigeration working fluid in the heat pump evaporator collects heat from the atmospheric environment, sends it to the condenser through the compressor to release the heat, and heats the air to heat the drying chamber.

There are open type, closed type, open and close integrated type, and direct heating type.

The listing of the dryer solves the problem that the clothes are always dry, especially for the rainy season in the south, when it rains, it will be more than a week, or even longer, and the clothes at this time will always not dry even if they are washed, and the dry clothes are damp, so the dryer is needed. So today, let's learn about the advantages and disadvantages of condensation drying and heat pump drying, which is better, heat pump dryer or condensation dryer.

Condensation drying and heat pump drying actually have the same drying effect, but heat pump drying is more energy-saving and power-saving, because it circulates the heat of drying clothes inside the machine, so that the heat can be reused to achieve the effect of drying clothes. The condensing dryer needs to heat the air first, and then use the hot air to dry the washed clothes, there is a condensing device at the exhaust outlet of the dryer, which can condense the steam released in the process of drying the clothes, and then discharge it together, because the condensing dryer does not have a drain pipe, so you need to pour water frequently.

If it is only from the drying method and energy saving of condensation drying and heat pump drying, of course, the heat pump dryer is more worth starting. Because the heat generated by the heat pump dryer can be continuously circulated, the energy consumption is relatively low. In addition, the power of the condensation dryer can reach 2,000W, while the power value of the heat pump dryer does not exceed 1,000W.

The heat pump dryer can accurately control the temperature at about 60 degrees, which is relatively low in damage to the clothes, and it also has a wool collection function, which can make the clothes be thoroughly cleaned.

The heat pump dryer adopts the technology of absorbing the heat in the external environment and the waste heat in the drying process, and forming a high-temperature gas transfer to the drying box to dry the items after the compressor is processed by the compressor; Mainly for rainy weather, direct sunlight, fast drying occasions; Intelligent mathematical sensing temperature control technology, which can preset the wind speed and temperature, can be set in one step, no need for special personnel to be on duty, professional structure air duct design, faster drying, and more power saving!

The air energy high-temperature heat pump dryer adopts heat pump drying equipment for the article baking unit, which eliminates the waste gas and waste residue pollution caused by combustion; And there is no external medium to change the texture of the baked object, which is more natural and environmentally friendly. The traditional drying room generally uses coal and wood as combustion materials, which will produce a lot of smoke and exhaust gas, which will cause great pollution to food drying and other drying. The control system of the air energy high-temperature heat pump dryer can accurately control the temperature of the drying constant temperature room, control the humidity exhaust damper with relative humidity to achieve the effect of drying and dehumidification, fully automatic implementation of drying procedures and data monitoring and fault feedback, and set up once and for all to achieve the effect of no special person on duty, reducing the investment of labor costs.

The compressor in the heat pump unit sucks low-temperature and low-pressure refrigerant (commonly known as refrigerant) gas from the evaporator, and compresses the refrigerant into high-temperature and high-pressure refrigerant through the work of the compressor. The high-temperature and high-pressure refrigerant gas enters the heat exchanger for heat exchange, and is condensed into a low-temperature and high-pressure liquid refrigerant in the heat exchanger to release a large amount of heat, which is converted into hot air through the fan, and the hot air is repeatedly circulated and heated in the drying box to heat the material so that the moisture in the material is continuously released and vaporized, and the material is finally dried through air dehumidification or condensation dehumidification.

1. The equipment cost of the heat pump drying device is mainly the heat pump part and the drying chamber part, of which the drying room part has the same requirements as the ordinary convection drying room, and there is no special air tightness and pressure bearing requirements.

2. Compared with the ordinary drying device (air temperature into the drying chamber "40"), the initial investment of the drying device is generally higher than that of the ordinary drying device because the initial investment of the heat pump dryer is generally higher than that of the air electric heating device and the gas or coal-fired hot blast stove.

3. The heat pump dryer drying device has high energy efficiency and low operating cost, and its comprehensive economy still has certain advantages.

Compared to the drying room, which uses pure electric heating to provide heat, heat pumps are more energy-efficient. For example, when the ambient temperature is 20 degrees, the outlet air temperature needs to be 60 degrees, and only about 25% of the electric heating power is needed in the heating process. At the required temperature, the energy consumption is 43% of that of electric heating. Therefore, under the premise of a long processing cycle and a large processing capacity, the transformation of the oven into a heat pump will save a lot of costs.

In general, it is mainly based on the cost of the first cycle to judge whether it is worth the transformation. The modification of the heat pump system often involves some changes in the production process, and if you do not want to change the production process, you need to calculate the configuration requirements of the heat pump more accurately. There are a lot to consider!

1. Temperature: Because of the heat pump system equipped with heat pump system, the heat of heat pump drying clothes only needs to circulate inside the machine, and the whole drying process does not generate heat externally; The condensing type requires a heater to heat the air, and some of the heat will be dissipated into the indoor environment;

2. Energy saving: the energy of the heat pump dryer is internal circulation, and less electricity is consumed; The condensing type needs to heat the air with electricity, which will emit a certain amount of heat, and the power consumption is relatively high.

Heat Pump Dryer Workflow:

1. The heat pump compression is used to pressurize the refrigerant to heat up, and the refrigerant is sent to the condenser to release heat, and the condenser is connected to the air path in the dryer to release dry air;

2. The pressure temperature of the refrigerant enters the capillary from the condenser and decreases rapidly, and then enters the evaporator, and the evaporator is also connected to the drying air path, turning the humid hot air into dry cold air, where the water vapor in the clothes condenses into small water droplets and is collected by the water collection tray;

3. The operation of the above-mentioned refrigerant, with the tumble in the dryer, and the drying fan to achieve the effect of drying clothes.
