How to keep a greenhouse warm?How to keep the greenhouse warm in winter?

Greenhouse heating and insulation can choose finned tube radiator, its heat transfer area is several times to dozens of times that of the light pipe, can strengthen heat transfer, reduce activity resistance, reduce metal consumption, and then advance the economy and working reliability of heat exchange equipment. The reason for these characteristics is that the structure of the high-frequency welded finned tube was improved during the planning and manufacturing process. The finned tube itself is coiled on the finned tube, and the high-frequency welding process is selected together to weld the sheet firmly on the tube to ensure the bonding strength of the tube and the fin, so the high-frequency welded finned tube has the advantages of high heat exchange power, large heat dissipation area and long service life.

The above is the answer made by Yushenghua radiator manufacturers for you, I hope it will help you, hope!

The winter weather is cold and unpredictable, and there is often a rapid cooling phenomenon, so it is necessary to do a good job of temporary heating of greenhouses. There are many measures that can be taken, but the following are common. The first is to add several heating fans in the shed to temporarily heat the temperature in a relatively low place, but it is necessary to pay attention to the high humidity in the shed to prevent leakage from causing adverse accidents.

Second, if there are conditions that can be used near the greenhouse, such as wineries and bathrooms, it can be fully utilized, which not only saves costs but also realizes the reuse of resources. The third is to cover the greenhouse with straw felt, which is a relatively backward insulation method, and it should be noted that it is necessary to ventilate on time and receive sufficient light every day. Because the important thermal insulation effect of the greenhouse plays a role in winter, some cold-proof systems can be added outside the greenhouse, which is very beneficial to the insulation in the shed.

The common ways are to erect wind barriers, dig cold-proof ditches, strengthen the soil, thicken the insulation film, etc., these application measures are in principle to isolate the greenhouse from the outside world, reduce the contact with the outside low temperature environment and heat exchange to achieve the purpose of insulation. It should be noted that the light time and light intensity should be ensured, one is because sufficient light can ensure the photosynthesis of green plants, and the other is that light can generate heat and increase the temperature of the greenhouse. In addition to the temporary heating system and the outdoor insulation system, how to use simple facilities and skills to achieve the purpose of indoor insulation is also very important.

Its principle is mainly to protect the temperature and heat in the vegetable greenhouse from loss and supplement the light to increase the heat. Common methods include installing fluorescent lamps in the shed to extend the light time, and erecting reflective film in the shed to collect external light and heat. Add ground coverage to green plants to ensure that the heat around the plants is not lost, use a thick curtain at the entrance and exit of the shed to prevent cold air from entering, and maintain the temperature in the shed The greenhouse does not have to be due south and north, the west sun is slightly better than the east in winter, so the west deviation of about 5 degrees can increase the light for nearly 20 minutes, but unfortunately there are too many base maps now that are beautiful and magnificent, like the shed due south and north.

If there is a slope in the west or a significantly higher slope in the west, then it is necessary to deviate to the east as appropriate, in short, according to local conditions.

The most common way is to cover the insulation quilt.

1. The greenhouse envy key insulation can choose natural heat preservation and forced heating, and natural heat preservation is the cover material with high light transmittance and good thermal insulation effect of the outer layer maintenance material of the greenhouse.

2. At present, the selection of PC sunlight board as the outer insulation material of the greenhouse is more and more Yueshan faction. Reason: long life, high-grade can reach more than ten years, no yellowing, no brittleness within ten years; High light transmittance, up to 80%; It is safer and less fragile than using glass; The structure of double-layer hollow or multi-layer hollow determines its good thermal insulation effect; It can be cold-bent into various arcs; the ability to withstand high winds and hail; Convenient construction.

At the same time, the greenhouse is tightly sealed to reduce heat loss. Forced heating depends on increasing the heat source indoors.

Greenhouse insulation with finned tube radiator bar. It is a good choice to choose finned tube for greenhouse heating, and the high heat dissipation efficiency of the greenhouse finned tube radiator is due to many reasons, the structural parameters of the radiator and the external environment will affect the heat dissipation efficiency of the radiator. For example, the spacing of finned tube radiators, generally speaking, the smaller the spacing, the higher the heat dissipation efficiency; The better the indoor thermal insulation performance, the higher the heat dissipation efficiency of the radiator.

The heat dissipation efficiency of a finned tube radiator is not determined by a single factor, but is the result of a combination of factors.

Finned tube radiator.

Greenhouse finned tube radiator is usually used in a large area of the place as a heat dissipation device for the hidden heating system, it is equipped with jujube heat dissipation efficiency, its heat dissipation efficiency can reach about 3-7 times of the ordinary radiator, its excellent heat dissipation effect, not only makes the finned tube in the heating system popular with people, in the field of drying is also more people's choice. The greenhouse finned tube radiator adopts a low-temperature heat dissipation method, low temperature does not mean that the radiator can be heated at a lower temperature, but the radiator adopts a step-by-step way to carry out uniform temperature dissipation, such a heating method is used in the drying workshop, which can not only ensure the efficiency of drying, but also ensure the texture of the drying material.

Finned tube radiator.

Greenhouse finned tube radiator is named according to the use of the environment for a finned tube radiator equipment, it is used in the greenhouse heating system, one is to provide a good growth environment for plants, animals and so on in the greenhouse, the second is to use the finned tube radiator can save a heating cost for the user, with a certain energy-saving performance. The energy-saving performance of the greenhouse finned tube radiator is mainly because it has good heat dissipation efficiency, excellent heat dissipation efficiency, and the time required to raise the indoor temperature is shorter, and the finned tube radiator also has a certain heat storage performance, after the equipment is turned off, the rest of the temperature can also ensure the uniformity of the indoor temperature.

1. Natural insulation and forced heating can be selected for the insulation of the greenhouse, and the natural insulation is the maintenance material of the outer layer of the greenhouse, which is a covering material with high light deficiency rate and good thermal insulation effect.

2. At present, more and more PCs are selected as the outer insulation material of greenhouses. Reason: long life, high-grade can reach more than ten years, no yellowing, no brittleness within ten years; High light transmittance, up to 80%; It is safer and less fragile than using glass; The structure of double-layer hollow or multi-layer hollow determines its good thermal insulation effect; It can be cold-bent into various arcs; Strong resistance to high winds and hail; Convenient construction.

At the same time, the greenhouse is tightly sealed to reduce heat loss. Forced warming depends on increasing the heat source in the room.

Summary. Common greenhouse insulation methods are brewing heat heating, electric heating, plumbing heating, warm air heating, solar energy storage system heating, etc., in the current era of energy conservation and emission reduction, the more recommended method is to choose solar energy storage heating system. The heat energy intercepted by the high temperature air that appears in the upper part of the shed is stored in the ground to increase the ground temperature, and when the night temperature is lower than the ground temperature, the energy stored in the soil can be dissipated into the air.

Through the use of solar energy storage systems, the ground temperature in the greenhouse can be increased by 1 2.
