Components and working principle of air energy heat pump

The principle of air energy heat pump is actually similar to that of air conditioner, and it is a new type of water heater.

Air energy heat pump is mainly composed of several parts: evaporator, compressor, condenser, liquid storage tank, expansion valve, etc., the whole set of equipment runs through a substance, refrigerant, the most common in reality is freon, the working principle is that the refrigerant in the evaporator and the air for heat exchange, absorb the heat of the air, (why will absorb the heat of the air, because the boiling point of this substance is very low, generally minus 40 degrees.) Because the object changes from liquid to gaseous state to absorb a large amount of heat, so the air here is relatively high temperature, so it will definitely absorb heat), after absorbing heat in the evaporator, it changes from liquid to gaseous state, enters the compressor, and the compressor processes this refrigerant into high-temperature and high-pressure steam, and then enters the condenser, in the condenser, the refrigerant and water carry out heat exchange, the temperature of the refrigerant drops, from the gaseous state of high temperature and high pressure to the liquid state, releasing a large amount of heat, and the water can absorb this heat, The refrigerant will return to the storage tank, waiting for the next cycle, the cycle of refrigerant repeatedly, the large amount of heat energy from the air to the water, first of all, the air source is because of a large amount of our energy is air, and secondly, why add a heat pump in the middle, because in our understanding, the pump is originally a device to improve the potential energy of water, that is, a device that pumps water from a place to a high place, and this kind of design is a device that brings heat from a low place to a high place. That's why it's called an air energy heat pump.

The air energy heat pump is mainly composed of several parts: evaporator, compressor, condenser, liquid storage tank, expansion valve and so on.

Working principle: Using the inverse Carnot principle, the equipment that transfers heat from a low-temperature object to a high-temperature water through a medium. It is mainly composed of compressors, heat exchangers, axial fans, insulated water tanks, water pumps, liquid storage tanks, filters, electronic expansion valves and electronic automatic controllers.

After the power is turned on, the axial fan starts to run, the outdoor air is heat exchanged through the evaporator, the air after the temperature is reduced is discharged from the system by the fan, at the same time, the working fluid inside the evaporator is sucked into the compressor, the compressor compresses the low-pressure working fluid gas into high temperature and high pressure gas and sends it to the condenser, and the water forced to circulate by the water pump also passes through the condenser and is heated by the working fluid and sent to the user for use, and the working fluid is cooled into a liquid, which flows into the evaporator again after throttling and cooling through the expansion valve. In this way, the heat energy in the air is continuously "pumped" to the water, so that the water temperature in the insulated water tank gradually rises, and finally reaches about 55, which is just suitable for people to bathe.

Air energyThe principle of heating isAir source heat pumpsThe principle.

A heat pump is a device that can obtain low-level heat energy from air, water or soil in nature, and provide high-level heat energy that can be used by people through electrical energy.

The four major components of a heat pump are a compressor and a condenser.

Throttling devices and evaporators.

After the low-pressure gaseous working fluid enters the compressor, it is compressed into a high-temperature and high-pressure gas, at this time, the boiling point of the working fluid rises with the increase of pressure, the working fluid with high boiling point enters the cold decondenser and begins to liquefy, the working fluid releases heat, and the working fluid that loses heat becomes liquid, and then enters the evaporator after the throttling device, and the throttling device reduces the pressure of the working fluid, and the working fluid after the pressure is reduced begins to evaporate in the evaporator, and then the working fluid absorbs heat and becomes a low-pressure gas, and then enters the compression hole machine, refrigerant.

In this way, it has been circulating, and selling envy and dryness is the principle of heat pump circulation, and it is also the principle of air heating.

How air energy heating works.

Heating, also known as radiators, radiators, heating radiators, etc., is the heat dissipation terminal of the heating system.

Air energy water floor heating working principle.

Floor heating is the abbreviation of radiant floor heating, which is a system that uses the entire ground as the heat dissipation surface, evenly heats the entire ground, and transmits heat from the ground from bottom to top (mainly using radiation) to achieve the purpose of heating.

An air source heat pump is an energy-saving device that uses high levels to make heat flow from low heat source air to high heat sources. This is a type of heat pump. As the name suggests, heat pumps, like pumps, can convert low-level heat energy that cannot be directly used (such as the heat contained in air, soil, and water) into high-level heat energy that can be used, so as to achieve the purpose of saving part of high-level energy (such as coal, gas, oil, and electricity).

Working principle: The heat pump uses the reverse Carnot principle to absorb a large amount of low-temperature heat energy in the air with very little electrical energy, which is converted into high-temperature heat energy after compression by the compressor and transported to the water tank to heat hot water. Therefore, it has the advantages of low energy consumption, high efficiency, fast speed, good safety and strong environmental protection, and can continuously improve hot water.

The working principle of air energy heat pump heating is that the air energy heat pump heating unit uses a small amount of electric energy to drive the compressor to work, inhale the low-temperature heat in the air, carry out heat exchange through the condenser or evaporator, heat the cold water, and then transport the hot water to the building through the circulation system, and finally meet the heating needs of users through the heating terminal (floor heating, floor heating machine, fan coil unit, etc.). ).

The low-grade heat energy in the air is compressed by the compressor and converted into high-temperature heat energy, and the water temperature is heated to no higher than 60 (generally the water temperature is 35-50), and as a heat medium, the decorative layer of the ground is circulated and heated in the special pipeline, so that the ground is heated through the heat transfer of ground radiation and convection.

Delivering heat from the air to indoor heating saves 200% of electricity, is 100% safe, and provides 24-hour heating. This combination of the above advantages of "air energy floor heating" quickly became popular in the market and was warmly sought after by urban consumers.

He works using the inverse Carnot principle. It can use relatively little electrical energy to absorb a large amount of low-temperature heat energy in the air, and then compress it through the compressor to turn it into high-temperature heat energy, which can then transmit the high-temperature heat energy to the water tank to make the water hot. Therefore, it has very low energy consumption, very high efficiency, fast speed, first-class safety performance, and does not cause pollution, and can provide people with hot water continuously.

1. The heat source of its system can be used together, and there is no need to set up a freezer room or boiler room according to the cold and heat, and the unit can be placed on the roof or the ground at will, which will not occupy the place for construction, and the installation is also very simple and convenient.

2. There is usually no water cooling system, so there will be no cooling water consumption, and there is no cooling water power Vvuzi consumption. As a result, there is no contamination of the cooling water. It is very safe and hygienic.

3. It also does not need to use a boiler, so without a boiler fuel system, there will be no dust and smoke removal system. Therefore, the whole system is very safe and reliable, and will not cause orange pollution to the environment.

4. The whole unit adopts modular design, and there is no need to configure a standby unit. In the process of working, the computer automatically controls and adjusts the state of the unit, so that the power and the environment complement each other.

5. The performance of the air source heat pump will change according to the outside climate.

6. In the northern part of our country, where the temperature is very low, the heat pump usually cannot supply enough heat in winter, so it is necessary to set up a heater to assist.

The principle of air energy heat pump: The refrigeration system of the heat pump consists of a compressor and two copper pipes (one indoors and one outdoors), and the copper pipes are surrounded by aluminum fins to help transfer heat. In heating mode, the liquid refrigerant in the outer coil absorbs heat from the air and evaporates into a gas.

When the refrigerant condenses into a liquid, the indoor coil releases heat. A reversing valve near the compressor can change the direction of the refrigerant flow to cool and defrost the outdoor coils during the winter months.

The efficiency and performance of today's air source heat pumps benefit from the following technological advancements:

The thermostatic expansion valve provides more precise control of the flow of refrigerant into the room coil.

Variable speed blowers, with greater efficiency, compensate for some of the adverse effects of pipe limitations, filter contamination and coil contamination.

Improved coil design.

Improved electric motor and two-speed compressor design.

Copper tubing, internally slotted to increase surface area.

The principle of air energy heat pump is explained as follows:The refrigerant is used as a medium for heat pumps, the vaporization temperature of the refrigerant is low, and it can be vaporized at -40, therefore, there is a temperature difference between it and the outside temperature, the refrigerant absorbs the temperature of the outside world and vaporizes, compresses the heating through the compressor, and becomes a high-temperature and high-pressure gas, and then exchanges heat with the water through the heat exchanger, releases the pressure through the expansion valve, returns to the liquefaction state of low temperature and low pressure, and heats the water in the tank through the continuous circulation of the refrigerant and exchanges heat with the water.

Does the heat pump need electricity? Be sure to use electricity, mainly in the compressor to compress the refrigerant, and the fan absorbs the heat in the air, not directly heating to generate heat, so it will be much less electricity, is an energy-saving and efficient product.

What are the characteristics of heat pumps? 1. It is not affected by the environment and can be used all year round.

2. The energy-saving effect is outstanding, and the investment period is short.

3. Environmentally-friendly products, without any pollution.

4. Long service life and low operating cost.

5. Safe operation, unmanned operation.

Do heat pumps belong to solar energy? In terms of working principle, it does not belong to traditional solar energy. Heat pump is quite different from conventional solar energy, conventional solar energy uses water as the medium, and must rely on direct sunlight or radiation to achieve the heating effect, while heat pump, the use of refrigerant to absorb heat energy and solar radiation energy in the air, and through the compressor compression heating and water exchange heat to achieve the heating effect, so the heat pump and air conditioning principle is the same.

The principle of air energy saving is nothing more than using a small amount of electricity to transport the heat in the air to heat water, unlike electric water heaters, which directly use electric heating rods to boil water. The heat in the air does not cost money, one of the money spent is the money to hire a professional porter (to buy air energy), and the other is to buy food for the porter (electricity).

In the operation of the air energy heat pump, the evaporator draws heat from the ambient heat energy in the air to evaporate the heat transfer working fluid, and the pressure and temperature of the working fluid vapor rise after compression by the compressor.

When the high-temperature vapor is condensed into a liquid by a special annular tube condenser permanently bonded to the outer surface of the tank, the heat released is transferred to the water in the air source heat pump tank. The condensed heat transfer fluid is returned to the evaporator through an expansion valve, where it is evaporated again, and so on.

Air energy heat pump heat transfer working fluid is a special substance, its boiling point is minus 40 under normal pressure, the freezing point is minus 100 below, the substance is liquid when cold, but it is easy to evaporate into gas, and vice versa. Spare space.

In actual operation, the evaporation limit temperature of the heat transfer working fluid in the air source heat pump is about minus 20, so the ambient temperature of 5 is also "hot" for such a low temperature, and even the temperature of snow, such as 0, is also hot in comparison, so it is still possible to exchange some heat energy.

Newentai Air Energy, Air Energy Heat Pump Indoor Water Circulation, the end of heat dissipation can be connected to floor heating, radiators and fans to judge the coil. The air energy heat pump absorbs low-grade heat energy in the air through low electricity and converts it into high-temperature heat energy required for indoor heating. The process is as follows:

First of all, the heat pump host is energized to absorb heat from the air, vaporize the absorbed heat through the evaporator, and then compress it into high-pressure gas through the compressor, and then enter the condenser to liquefy the trace, and transmit the absorbed heat to the water circulating by the heat exchanger. This process is repeated continuously, absorbing low-temperature heat from the low-temperature environment and converting it into high-temperature heat, and then transferring it to the indoor heating water to provide a continuous heat source for indoor heating until the indoor temperature reaches the set temperature.
