An air conditioning system and control method for an aquaculture plant, the system comprises: a casing, a heat pump unit and a throttle valve; a first heat exchanger is arranged inside the casing; the heat pump unit includes a second heat exchanger and a compressor part; The compressor part, the first heat exchanger, the throttle valve and the second heat exchanger are connected in sequence to form a medium circulation loop; the second heat exchanger is used to realize the heat exchange between the aquaculture wastewater and the heat conducting medium in the medium circulation loop; the first heat exchange The device is used to realize the heat exchange between the return air and the heat conducting medium in the medium circulating circuit; the medium circulating circuit is also provided with a reversing valve, which is used to adjust the flow direction of the heat conducting medium on the medium circulating circuit. By changing the state of the heat conduction medium, the invention efficiently absorbs the cold/heat of the aquaculture wastewater, thereby efficiently utilizing the residual temperature of the aquaculture wastewater, greatly reducing the temperature field regulation cost of the aquaculture farm, and has a simple structure and is easy to transform. |
