Description

Edible mushroom cultivation room air conditioner

technical field

The utility model relates to an air conditioner for an edible fungus cultivation room. The inoculation device belongs to the field of facility agriculture and is mainly used for intensive and industrialized edible fungus production.

Background technique

The basic principle of intensive and factory production of edible fungi is to use air-conditioning equipment and automatic measurement and control devices related to temperature, humidity and light, in a closed edible fungus cultivation "room" similar to a cold storage, through the "room" The automatic measurement and control of main environmental conditions such as temperature, humidity, _CO2 concentration, and light form an optimal environmental condition most suitable for the growth of edible fungi, and through the gradual development and improvement of edible fungus cultivation facilities, a complete set of A complete artificial production system of edible fungi. The use of factory production facilities and advanced measurement and control equipment to artificially set the best environmental conditions for the growth of edible fungi can not only shorten the growth cycle of edible fungi, but also greatly improve the efficiency and quality of edible fungus production; Edible fungi are produced in the off-season or even all year round in conventional production, which can make up for the shortage of off-season vegetables and increase the price of fresh edible fungi like off-season vegetables. Because the environmental conditions for the production of edible fungi are superior and can be adjusted according to different requirements, it is more conducive to the introduction, renewal and large-scale production of new varieties of edible fungi.

In the total energy consumption of the industrial production of edible fungi, the energy consumed by the edible fungus cultivation room for cooling in summer and heating in winter accounts for a considerable proportion. For ordinary central air-conditioning systems, whether it is an air-cooled heat pump unit or a chiller unit using a cooling tower, without exception, it is limited by the external weather conditions, that is, when the air-conditioned area needs more cooling or heating, the cooling capacity of the host Or the heat supply will be insufficient, resulting in a decrease in operating efficiency, which is especially affected when used in hot summer and cold winter regions. The heat exchange between the ground source heat pump unit and the outside world is through the ground, and the temperature of the ground is very stable, and the operating efficiency is not affected by changes in the outside air. Therefore, the ground source heat pump has the highest operating efficiency and the best stability. From the point of view of the entire operating principle of the ground source heat pump, the ground source heat pump system is actually a green air conditioner in the true sense. Whether it is running in winter or summer, it will not cause adverse effects on the outdoor atmospheric environment. At present, the ground source heat pump system is one of the mature technologies in the world's energy market. If environmental benefits, energy security and long-term utilization are considered, the ground source heat pump system is the best and most technologically-intensive alternative product. Groundwater ground source heat pump has many advantages such as simple structure and easy construction, and has been gradually applied and promoted.

Most of the existing groundwater ground source heat pumps use groundwater to directly cool the condenser of the heat pump unit or directly heat the evaporator of the heat pump unit. A ground source heat pump system disclosed in Chinese Patent Publication No. CN1854645 is composed of an evaporator, a condenser, a compressor and an expansion valve. The well water flows through the evaporator or condenser respectively as required, and the temperature difference between the groundwater body and the ambient air is fully utilized to adjust the temperature of the indoor circulating water. However, the edible fungus cultivation room requires an air duct air conditioning system. The ground source heat pump system does not use the natural cold or heat stored in the groundwater for cooling or heating of the outdoor fresh air, so there are obvious deficiencies in terms of energy utilization. The invention provides a ground source heat pump air-conditioning air supply system applicable to the occasion of an air duct system, and is especially suitable for an edible fungus cultivation room.

Edible fungi are aerobic fungi, and it is difficult to survive without O ₂ (wind). Therefore, the growth of mycelium needs sufficient fresh air (O ₂ ). Without O ₂ , the growth of mycelium will be hindered and slow, which will affect the growth and development, and even the mycelium will suffocate and die or autolyze, causing fruiting bodies to get sick and miscellaneous bacteria to breed. Especially when the density of the fungus bag is too high, the supply of _O2 is insufficient, which will affect the growth of mycelium. In the early stage of mushrooming in the loose bag, the mycelium will decompose faster, breathe more vigorously, and the temperature in the bag will increase. Fermentation is sour, unpleasant smell, and stuffy feeling; it is more necessary to strengthen ventilation, reduce temperature and increase oxygen, eliminate indoor pollution, and purify the ambient air. From the perspective of edible fungus culture medium, the CO ₂ released during the transformation process of mycelium feeding material has serious harm to the growth of edible fungi. When the _CO2 content in the air exceeds 0.3%, if it is not discharged in time, the viability of mycelia will decrease, the resistance to stress and miscellaneous properties will be weakened, the mushroom buds will wither and die in the mulberry stage, and the fruiting bodies will shrink and deformed mushrooms will seriously affect the quality and quality. Yield.

To sum up, the air handling unit in the edible mushroom cultivation room needs to supplement a large amount of outdoor fresh air to adjust the air. Since the present invention directly utilizes the natural cooling capacity stored in groundwater or outdoor fresh air with a large amount of heat for cooling or heating, the utilization rate of energy consumption is significantly improved, especially in hot summer and cold winter regions, and the energy saving effect is better. In addition, the humidity control range of the edible mushroom cultivation room is usually 65-85%, while the existing air duct air-conditioning system takes away a large amount of water during the process of temperature control, filtration, and oxygenation, resulting in low air humidity entering the cultivation room; Therefore, one or several humidifiers have to be added indoors to increase the humidity of the indoor environment. Since there is a considerable distance between the air supply point of the air conditioner and the humidification point of the humidifier, no matter where the temperature and humidity probe of the cultivation room environment automatic measurement and control device is set, it is difficult to reflect the indoor temperature and humidity at the same time.
