Cold storage available ground source heat pump, for soil source technology, in the process of equipment operation, the cold storage system all year round to the soil heat discharge, very easy to cause soil heat imbalance.
In modern society, with the economic development and technological progress, more and more cold storage and dry storage is widely used in food, medical, chemical and other fields, cold storage and dry storage energy consumption is generally high, reduce the cold storage and dry storage operation energy consumption is critical.
The vast majority of cold storage and dry storage using air source heat pump technology, in unfavorable working conditions, such as cold storage corresponding to the high temperature of summer, higher outdoor temperature corresponds to a higher condensing temperature, which will significantly increase the refrigeration cycle compressor power consumption, thus reducing the unit operating EER.
For dry storage corresponding to the low temperature of winter, lower outdoor temperature corresponds to a lower evaporation temperature, the same will increase the heat pump cycle compressor power consumption, and thus reduce the unit operating EER.
Ground source heat pumps can use renewable shallow geothermal energy, the year-round moderate and stable temperature of the underground soil or groundwater as the cooling side of the refrigeration system or the heat pump system heat source side, so that the refrigeration system has a relatively low condensing temperature, the heat pump system has a relatively high evaporating temperature.
