Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural planting device technical field, concretely is a double-spore mushroom house temperature control system. BACKGROUND

[0002] Double-spore mushroom is a kind of delicious, large-scale cultivation, wide range of edible fungi;Its protein content is as high as 42%, rich in amino acids, nucleotides and vitamins and other nutrients.Double-spore mushroom has been widely cultivated in our country, and the planting company constructs professional mushroom house, and double-spore mushroom planting frame is arranged in the mushroom house, and double-spore mushroom is planted in the substrate on the planting frame.Double-spore mushroom is suitable for growing in warm and humid environment, and the most suitable growth temperature is 23-26 DEG C, and the humidity needs to be kept between 85%-95%.Therefore, temperature and humidity control system must be carried out in the mushroom house to maintain the suitable growth conditions of double-spore mushroom.In the hot summer of southern region, temperature control mainly relies on air conditioning system, and in the particularly hot summer, air conditioning system power is high, and the cost of power consumption becomes one of the costs that cannot be ignored for double-spore mushroom planting.

[0003] In order to balance the power generation efficiency of power plant, power grid load and social electricity demand, electricity is often divided into peak electricity and valley electricity two stages, in the power peak period, that is, daytime period, according to the peak electricity price, the price is higher, in the power low peak period, that is, midnight period, according to the valley electricity price, the price is lower.Therefore, if the mushroom house can store the energy of valley electricity period and release it when the peak electricity, a large amount of money cost of power consumption can be saved, and for large-scale double-spore mushroom planting, it will produce the economic benefit that cannot be ignored. SUMMARY

[0004] The utility model aims at providing a double-spore mushroom house temperature control system, utilizes the phase change material to be laid in the top of mushroom house, utilizes valley electricity period refrigeration equipment to store the cold quantity in phase change material bag, waits for the peak electricity stage, and the cold quantity in phase change material bag is released to the mushroom house, can effectively reduce the running power of temperature control air conditioner, and then reduces the overall electricity expense.

[0005] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0006] A double-spore mushroom house temperature control system, temperature control air conditioner and energy storage refrigerator are arranged in the mushroom house, and phase change material layer is arranged on the top of the mushroom house, the energy storage refrigerator includes compressor, expansion valve and evaporator, wherein the pipeline of compressor and expansion valve is connected with coil, and the coil is arranged close to the phase change material layer.

[0007] The energy storage refrigerator is started at a valley power period, and functions to accumulate cold energy in the phase change material layer, and the energy storage refrigerator is stopped at a peak power period, and the cold energy in the phase change material layer is slowly released, so that the operation pressure of the temperature control air conditioner in a daytime period is reduced, and the overall energy consumption can be reduced; although two refrigeration devices need to be installed in each mushroom house, the highest peak of refrigeration is reduced due to the existence of the energy storage refrigerator, the peak is filled with the valley, and the temperature control air conditioner can correspondingly adopt a small refrigeration device with lower power, so that the equipment investment is also reduced to a certain extent.

[0008] On the other hand, since the phase change material layer is laid under the roof, most of the heat of the direct sunlight is insulated and absorbed by the phase change material layer, so that the heat received by the interior of the mushroom house below is greatly reduced, and the construction investment of the heat insulation layer on the top of the mushroom house is also saved to a certain extent.

[0009] The phase change material layer is composed of a plurality of phase change energy storage units suspended below the roof of the mushroom house by hangers, and each phase change energy storage unit comprises a phase change material soft package loaded in a groove composed of a frame and a grid bottom plate.

[0010] The phase change energy storage unit is fixed in a suspension mode, the upper end of the hanger is fixed and anchored through nut fixing after penetrating the roof, and the lower end of the hanger is fixed by welding. The grid bottom plate has a gap, which can better enable the lower surface of the phase change material soft package to contact and exchange heat with the air in the mushroom house, so that the cold energy of the phase change material is transmitted to the mushroom house below, and the release of cold energy is realized.

[0011] The phase change material soft package is composed of a flexible PVC outer package and a phase change material. The phase change material is composed of hydrated salt, expanded graphite and aluminum copper powder, and the phase change temperature is 20-23 DEG C. During the valley power period, the phase change material is cooled to below 20 DEG C, and a large amount of cold energy is stored in the form of solid phase. During the daytime hot period, the cold energy stored in the phase change material is gradually released, and the phase change material returns to the liquid state. The process is repeated.

[0012] The cross section of the coil pipe is a flat tube, and the lower end surface of the flat tube is in close contact with the upper surface of the phase change material layer.

[0013] The lower surface of the flat tube can be in contact with the phase change material layer in a larger area, so that heat transfer occurs and the heat exchange between the refrigerant in the refrigeration device and the phase change material is improved.

[0014] Advantages of the utility model

[0015] (1) The utility model utilizes the phase change material laid on the top of the mushroom house, and the cold energy is stored in the phase change material package by the refrigeration device during the valley power period, and the cold energy in the phase change material package is released into the mushroom house during the peak power period, so that the operation power of the temperature control air conditioner can be effectively reduced, and the total electricity bill can be reduced.

[0016] (2) The phase change energy storage layer in the utility model can replace the original heat insulation layer on the top of the Agaricus bisporus house, and reduces the temperature rise of the Agaricus bisporus house caused by sunlight irradiation on the top of the Agaricus bisporus house.

[0017] (3) The utility model can reduce the number of temperature control air conditioners, and the small-power air conditioner can meet the cooling demand of the Agaricus bisporus house. BRIEF DESCRIPTION OF DRAWINGS
