Abstract

The invention discloses a coupled heat pump system which includes an air source heat pump unit, a water source heat pump unit, a first waterway, a second waterway and a third waterway. The air source heat pump unit includes a first compressor, a four-way valve, an outdoor heat exchanger and an indoor heat exchanger. The outdoor heat exchanger and the indoor heat exchanger are connected with the first compressor through the four-way valve respectively. The water source heat pump unit includes a second compressor, a condenser and an evaporator, wherein the condenser and the evaporator are connected with the second compressor respectively. Two ends of the first waterway are suitable to be connected with a use side backwater end and a use side water outlet end respectively. Two ends of the second waterway are suitable to be connected with the use side backwater end and the use side water outlet end respectively. The indoor heat exchanger and the evaporator are arranged on the third waterway. The coupled heat pump system can output hot water at high temperature in the low temperature environment.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a coupled heat pump system. Background technique [0002] In the existing air source heat pump (cold and hot water) units, when the ambient temperature is lower than -15°C, the heating capacity of the air source heat pump unit is greatly attenuated, and the energy efficiency is reduced; the temperature of the hot water it provides is generally lower than 45°C The following cannot meet the customer's use requirements. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the purpose of the present invention is to provide a coupled heat pump system, which can output hot water at a higher temperature in a low temperature environment, and has lower energy consumption. [0004] The coupled heat pump system according to the present invention includes: an air source he...
