What is the best way to heat the greenhouse indoors?

Greenhouse indoor heating, greenhouse galvanized finned tube radiator is suitable for the special environment in the greenhouse to use a heating equipment, the greenhouse is planted in the conditions of fruits, vegetables or flowers and other living conditions for the temperature requirements are very high fragile substances, the temperature is too high and too low will affect the growth of plants, so there is a finned tube radiator.

Finned tube radiator.

The galvanized finned tube radiator in the greenhouse can well sense the temperature change in the greenhouse, and use its own temperature control system to provide a reasonable temperature environment for the plants in the greenhouse. The finned tube radiator can operate in the range of up and down 5 of the set temperature, that is, it will stop when the temperature is higher than the set temperature of 5, and the heating will be turned on when the temperature is lower than 5 of the set temperature. <>

The grass can be covered in time, and the thickness of the mulch can be increased, and at the same time, the tree protection general can be sprayed in the greenhouse to keep warm and anti-freezing.

Under certain climatic conditions, the solar greenhouses and greenhouses designed and built generally do not need to be heated, but in case of special low temperature weather, even rain and snow, or if you want to make cherries, nectarines, apricots and other fruits ripen earlier and go to market, the method of auxiliary heating is often used to obtain higher benefits.

1. Furnace heating: This method can be divided into two types: planned heating and temporary heating. Planned heating is the design of a stove on the north wall during the construction of a solar greenhouse, using coal as fuel, the furnace outside, and the heat is fed into the fruit tree greenhouse through a tile pipe or brick flue. Temporary heating is direct heating in the greenhouse due to special weather.

It is best to use charcoal as fuel when heating the shed to avoid soot causing harm to fruit trees and people (but you should be aware of the hazards of toxic gases such as carbon monoxide). In rainy and snowy days, iodine-tungsten lamp (1000W) can also be used to irradiate, which can not only increase temperature but also supplement light.

2. When the electric heater is heated to temporarily supplement the greenhouse temperature, the method of heating the household electric heater can also be used. An electric heater that can be turned and blown to dissipate heat should be used. Note that the electric heater should be kept at a distance of more than 2 meters from the fruit tree, but because the inner fruit tree is only about 1 meter away from the wall, the electric heater can be blown in the southeast and southwest direction, and the heat dissipation surface of the electric heater should be tilted upwards by 15 degrees to 20 degrees, and do not blow the fruit tree directly.

3. Heating heating: If a large area of solar greenhouses and greenhouses or sheds are built in residential areas and have heating conditions, heating can be used; Or send the water into the boiler for heating, so that the water becomes steam, hot water or warm water, and is introduced into the iron pipe or radiator in the fruit tree greenhouse through the conveying iron pipe to increase the temperature, and after cooling, it is returned to the boiler from the return pipe to reheat, and the cycle is continuous. Hot water heating is the most ideal, and the temperature is stable, uniform and long-lasting. There are two ways to dissipate heat in the shed, one is to install the heat dissipation parts on the north wall and the bottom foot of the south side of the solar greenhouse, or in the middle of the plastic greenhouse; One is to spread the heat pipes evenly on the ground.

4. Electric heating This method has two methods: ground heating (burying electricity in the greenhouse soil to increase soil temperature) and air heating, which has a better use effect but a higher cost. Electrical** is made of millimeter 70 carbon alloy steel wire as a resistance wire, and is wrapped with a strong heat-resistant vinyl resin as an insulating layer. Use an electronic relay to control the temperature, enter the desired temperature range, and it can be automatically controlled.

5. Hot water bottle heating during the day in the fruit tree greenhouse to place water bags, the specific heat of water is large, can absorb sunlight energy during the day, and convert it into heat energy to store, in the night when the shed is cooled, gradually release heat energy, so as to improve the temperature of the greenhouse.

The most economical greenhouse heating, the model of the greenhouse flange finned tube radiator is usually formulated according to the needs of the user, so it has a variety of models. Regardless of the type of finned tube radiator, it is usually installed in two forms: wall-mounted and stand-up, and it is also installed according to the requirements. Wound finned tube radiators are usually designed according to the actual situation of the room, in which the height and width of the radiator are important factors affecting the heat dissipation efficiency of the radiator.

In one experiment, a 70 mm heat sink was shown to transfer heat better than a 95 mm heat sink, so it was not the higher the finned tubes that dissipated the heat better.

Finned tube radiator.

Greenhouse flange finned tube radiator is a kind of finned tube radiator, which uses steam as the main medium of heat conduction, steam absorbs heat from the heat source, and the heat medium becomes refrigerant in the process of flowing heat dissipation, and the refrigerant flows back through the return pipe to continue heating, and turns into a heat medium to continue to emit. Finned tube radiators are used more in industrial workshops in the current field of use. The basic performance of the equipment of the industrial finned tube radiator is mainly required according to the working environment, due to the special heating environment of the industrial workshop, the production requirements of the industrial finned tube radiator are more stringent than the production requirements of other radiators.

Finned tube radiator.

After the installation of the greenhouse flange finned tube radiator, we also have to carry out some maintenance on the radiator, and the correct maintenance can maintain the heating efficiency of the radiator and prolong the service life of the radiator. When the radiator is not in use, we must maintain it with full water to prevent the air from corroding the radiator. <>

1. Heat the fire.

Furnace heating is the most commonly used traditional heating method with a long history. A fixed stove can be used, or a makeshift stove can be used for heating. Furnace heating is mainly used in greenhouses, and later with the development of plastic greenhouses, it is also gradually applied to the production of greenhouses in early spring.

2. Warm up with hot water.

Use heating pipes and radiators to heat the heat. The use of hot water heating in China is not very common, and it is only limited to the use of large glass greenhouses and contiguous concentrated greenhouse groups. The advantages are:

It is conducive to the heating of large-area greenhouse groups; When heating, the indoor temperature can be kept uniform, which is convenient to promote the rise of ground temperature; The residual heat has a long time, and there is a period of heat preservation after the heat is stopped; There are no harmful gases and soots.

3. Steam heating.

It is less used in our country, and its heating method, the advantages and disadvantages are the same as that of hot water heating, but the hot water is changed to hot gas, and it is also convenient for soil disinfection. It can use the waste heat and exhaust gas of the power plant to combine with agriculture.

It is best to use charcoal as fuel when heating in the shed.

You go to know about Tongkai Electronic Technology's Hongjiaoyang Laser Greenhouse Warming King, I have been using this product, and the effect is very good. Technology products are very worry-free to use. More on that below.

The most commonly used type of heating is the type of heating, and the airfoil type heating is most commonly used in greenhouses because it is cheaper. (Personally, it is estimated that a shed may cost about 20,000, and you can search for a round airfoil radiator on the Internet).

There are also stove burners.

The thermal insulation performance of the solar greenhouse is relatively good, and the cost is relatively low (that is, the kind of film on one side and the earthen wall on the other).

Greenhouse indoor heating, greenhouse aquaculture radiator fin tube heat exchanger used fin tube two kinds of fin tube and outer fin tube, of which the outer fin tube application is more common. When the finned tube radiator is installed in a safe way to operate, it is necessary to understand the characteristics of the design structure to ensure that the medium in the tube can be drained after use or deactivation. Therefore, when installing the finned radiator, it is necessary to equip the corresponding media piping system according to the design, and the occlusion ball valve should be installed on the return line of the steam and hot water lines.

In order to ensure that the heat-resistant and wear-resistant fin radiator presents a better parameter effect, it is also necessary to make bracket support for the inlet and outlet pipelines, and only the distributed load-bearing can ensure that the fin radiator is more safe and reliable after installation and use, and the correct installation and operation mode can fundamentally ensure the stability of the fin radiator.

Finned tube radiator.

Greenhouse aquaculture radiator finned tube radiator (referred to as radiator, also known as heat dissipation pipe, air heater, air heat exchanger): is to cool the air with refrigerant, or heat the air with a heat medium, or to use cold water ** air waste heat, and other heat exchange devices in the main equipment. High-temperature water, steam, or high-temperature heat transfer oil can be used to heat the air and salt water or low-temperature water to cool the air.

At present, the widely used fin radiator is steel and aluminum fin tube (wound type steel and aluminum composite fin tube, rolled steel and aluminum composite fin tube), which uses the pressure resistance of steel pipe and the thermal conductivity of aluminum, and is composed of machines in use. <>

Indoor heating in the greenhouse is still economical.

For vegetable greenhouses, industrial workshops, drying rooms for large-area heating, what we need is high heating efficiency, economical, after all, thousands of square meters of workshops need to spend a lot of heaters, but also easy to clean, otherwise a large space, as well as machine work, easy to accumulate dust, and high-frequency welded fin tube heating and light pipe heating is exactly what people need. Industrial finned tube radiator is a kind of radiator developed in recent years by finned tube, light tube plugging and welding as one of the heat dissipation efficiency, high pressure, energy saving, its specifications and models are divided into 40-114 range, mainly used in greenhouses, large workshops, office workshops, stations, airports, coal mines, due to the thick pipe diameter, large water capacity, high heat dissipation, good thermal conductivity effect of peripheral fins, is several times or even dozens of times the heat dissipation of general radiators, can greatly save on cost, It is ideal for many industrial heating.

Hello! The commonly used methods of greenhouse heating are furnace fire heating, hot water heating, steam heating, warm air heating, solar energy storage system heating, etc., and according to different areas of greenhouses, as well as the actual situation, which way is the most economical and cost-saving, in fact, it is not completely certain, it is best to take measures according to the actual situation.

However, in general, solar heating will be more economical, and the power consumption will be high when the stove is heated.

The history of furnace heating is relatively long, and it is also a commonly used traditional heating method, which can generally take a fixed stove, or use temporary stove heating, furnace heating is mainly used in greenhouses, and later with the development of plastic greenhouses, it is also gradually applied to the production of greenhouses in early spring.

There are three common heating methods, hot water, hot air and electric heating.

Each method is quite convenient to use in practice, and can reach the desired room temperature in a very short time.

Heating heating: In case of extremely cold weather, you can add a stove or turn on the heating in the greenhouse, but special attention should be paid to prevent gas poisoning from flowers and staff, and a chimney should be installed to output the gas outside the shed. Plus mulch:

At night, cover the shed in the greenhouse and cover the straw curtain, and add grass or corn stalks around the greenhouse at night, which can increase the temperature by 1-2.

1. Commonly used warming methods.

Cover the quilt, build the sail film, alcohol stove, fluorescent lamp, etc., these are common warming methods, which will be used in cold sheds and warm sheds. These two methods are more cost-effective with alcohol stove and fluorescent lamp, and it takes about ten dollars to travel in a greenhouse for seven or eight points, and the warming effect can also be used. Second, the new type of heating equipment to raise the temperature.

In winter, it is inevitable that there will be extreme weather, especially at night, when the minimum temperature reaches zero degrees, or some greenhouses have a large area, and some conventional warming methods cannot increase the temperature quickly. At this time, we need to use other heating equipment of Bihail, such as heating blocks, heaters, and electric boiler heating methods.
