Problems solved by technology

[0004] 1. In winter (especially in northern China), if the greenhouse maintains a certain temperature, a boiler must be used. This method is not suitable for controlling the temperature in the greenhouse (the temperature required by many crops during the day and at night varies greatly)
In summer, the temperature can only be reduced by ventilation, but the effect is limited
[0005] 2. Most greenhouses can only adjust the room temperature in the greenhouse but cannot adjust the temperature of the soil, especially in winter, the lowest temperature (15 degrees) for the normal water absorption and fertilizer absorption of crop roots cannot be reached.
[0006] 3. The temperature of the greenhouse cannot be set numerically in winter and summer
[0007] 4. The humidity inside the greenhouse in the summer rainy season is too high (over 80%), which is not conducive to the growth of crops. The existing greenhouses cannot adjust the humidity, so they cannot provide the most suitable humidity for the growth of crops
[0009] 6. Boilers are mostly used for heating in existing greenhouses. Coal-fired boilers will cause environmental pollution, and the cost of oil-fired boilers is too high

Embodiment 2

[0030] In areas with abundant groundwater, the external geothermal energy exchange system can also adopt a groundwater heat exchange system composed of pumping wells and recharge wells. like image 3 As shown, two wells can be drilled, one is a pumping well 6-1, and the other is a reinjection well 6-2, and all the other structures are identical with example 1.

Embodiment 1

[0031] Embodiment 1 working process:

[0032] Underground heat exchange system: The ground-source buried pipe system uses the energy in the shallow underground soil as a cold and heat source. By embedding HDPE high-density polyethylene plastic pipes around the greenhouse, the heat exchange medium in the plastic pipes is supplied by a circulating pump. It drives a fully closed cycle, and exchanges heat with the soil under different operating conditions. In the heating state, it absorbs heat from the soil, absorbs and transmits the heat to the ground temperature host equipment, and in the cooling state, guides the indoor heat back and stores it in the soil.

[0033] Ground temperature host system: In winter, the heat exchange medium that absorbs the low-grade heat in the soil enters the evaporator of the ground temperature host equipment, and exchanges heat with the low-temperature refrigerant in the circulation pipeline, and the low-temperature refrigerant absorbs the heat of t...

Abstract

The invention discloses a greenhouse with a constant temperature adjusting function. The greenhouse comprises a main body of the greenhouse and internally provided with ground temperature host equipment used for a ground-source heat pump system. The ground temperature host equipment is connected with an end system of the greenhouse and a geothermal exchange system so that a supply / return loop for temperature adjustment is formed. The end system comprises PE-X, PE-RT or PD heat exchange pipes uniformly and horizontally buried on surface soil of the greenhouse as well as vertical fan coils installed around the interior of the greenhouse. The geothermal energy exchange system can serve as PE heat exchange pipes vertically buried on the soil and also serve as a groundwater heat exchange system composed of a pump well and a recharge well. The greenhouse with the constant temperature adjusting function has following beneficial effects: air temperature can be automatically controlled and regulated such that air can be kept at a constant temperature during four seasons; soil and air humidity can be regulated in order to accommodate to growth of crops and keep soil at a constant temperature during four seasons; organic-matter degradation in soil can be reduced and content of organic matters is increased; soil hardening and salination are avoided; the greenhouse can save energy and protect the environment so that air pollution caused by coal burning is avoided.

Description

technical field [0001] The invention belongs to the technical field of greenhouses, and in particular relates to a greenhouse with constant temperature adjustment function. Background technique [0002] With the continuous improvement of people's living standards, the planting and breeding industries have developed rapidly. The greenhouse is a necessary basic facility for planting and breeding. Due to the natural phenomena of the four seasons and day and night, the temperature in the greenhouse will change greatly. How to adjust the temperature in the greenhouse is a problem that must be solved in the greenhouse. [0003] The current status of regulating the temperature in the greenhouse: [0004] 1. If the greenhouse in winter (especially in northern China) maintains a certain temperature, a boiler must be used. This method is not suitable for controlling the temperature in the greenhouse (the temperature required by many crops during the day and at night varies greatly)...
