The invention discloses a wind and hydraulic double-source
heat pump water chilling and heat unit and a control method thereof. The wind and hydraulic double-source
heat pump water chilling and heat unit comprises a four-way valve, one of the connecting ports of the four-way valve is connected with a shell-tube
heat exchanger and an
economizer, and the other three connecting ports of the four-way valve are connected with a gas-liquid separator, a fin type
heat exchanger and a plate type
heat exchanger; the gas-liquid separator is connected with the inlet of a compressor, and the outlet of the compressor is connected with the plate type heat exchanger; the shell-tube heat exchanger is connected with the
economizer, and the
economizer is connected with the fin type heat exchanger, the shell-tube heat exchanger and the compressor; the plate type heat exchanger and the shell-tube heat exchanger are connected with an external
water source, and the fin type heat exchanger is connected with a fan. Compared with the prior art, the wind and hydraulic double-source
heat pump water chilling and heat unit has the advantages of being capable meeting the requirements of users on cold water or hot water at any time through an air source and the
water source, namely, being capable of achieving automatic switching among an air source heat pump mode, an
air cooling cold water mode and a
water source heat pump mode according to the requirements on the cold water or hot water and integrating three different functional units into one multifunctional unit, thereby achieving refrigerating and heating through the air source and the water source all around the year according to the cooling and heating requirements of the users.
