Abstract

The invention relates to a temperature control system for an aquaculture earth pond with a wind-shui dual heat source heat pump type, comprising: a refrigerant circulation circuit module, a water source circuit module, an air source module, a water source circuit module, a heat exchanger assembly and a four-way valve. The refrigerant cycle assembly includes a first electronic expansion valve, a second electronic expansion valve and a compressor, the air source module includes an axial fan, an air source heat exchanger, and a third electronic expansion valve, and the water source circuit module includes The first circuit of water source and the second circuit of water source. Compared with the prior art, the present invention can realize water source heating mode, air source heating mode, water source and air source simultaneous heating mode and cooling mode, and can significantly improve the energy efficiency of the heat pump unit. The pond water with a temperature of 10°C is higher than that to obtain heat, which greatly improves the COP of the system; in addition, it is also possible to use one heat-extracting soil pond to supply heat or cool down to multiple cultured soil ponds at the same time.

Description

technical field [0001] The invention relates to a heat pump system with dual heat sources, in particular to a heat pump type aquaculture earth pond temperature control system with Feng Shui dual heat sources. Background technique [0002] At present, earthen ponds manually excavated outdoors are the main place for aquaculture, but the water temperature of earthen ponds is greatly affected by the outdoor environment, especially in cold winters, it is necessary to maintain the water temperature through heating to maintain the output of aquaculture. Traditional heating methods use coal-fired boilers or gas-fired boilers. Coal-fired boilers use low-quality coal with low calorific value and high ash content. The incomplete combustion of coal produces a large amount of soot and sulfur dioxide, which pollutes the atmospheric environment. Some areas have begun to completely ban Coal-fired boiler. The operating cost of gas-fired boilers is extremely high, which greatly reduces the p...
