Problems solved by technology

However, when the heat recovery function is started in the cooling mode, the temperature of the heat recovery water tank is often too low or too high to cause unstable operation of the unit, resulting in large changes in the load of the condenser, unstable system, low-voltage protection or repeated startup of the unit Phenomenon

Abstract

The invention discloses a control method for a heat pump system, the heat pump system and an air conditioner. The control method for the heat pump system comprises the following steps: judging whether a heat recovery mode is allowed to run according to the temperature of a heat recovery medium which is to be subjected to heat exchange with a refrigerant, and / or, when the heat recovery mode is allowed to run, controlling a compressor in a refrigerant circulating loop to start / stop according to the temperature of the heat recovery medium which is to be subjected to heat exchange with the refrigerant. According to a control method for a heat recovery device, whether the heat recovery mode is allowed to run and whether the compressor is started / stopped are controlled by the temperature of the heat recovery medium. By actively inhibiting the heat recovery device from running or actively stopping the compressor, the running stability of the heat pump system cannot be influenced by excessively high or excessively low temperature of the heat exchange medium, or the phenomenon that the compressor is repeatedly started / stopped is prevented. Not only can the running stability and comfort of the heat pump system be guaranteed, but also the stability of the heat recovery function is ensured, and domestic hot water is provided for users.

Description

technical field [0001] The invention relates to the technical field of heat recovery, in particular to a heat pump system control method, a heat pump system and an air conditioner. Background technique [0002] The heat pump system with heat recovery function can recover heat through the heat recovery device, and use the recovered heat to heat domestic water and provide domestic hot water to users, which not only reduces energy waste, but also brings convenience to users' lives . However, when the heat recovery function is started in the cooling mode, the temperature of the heat recovery water tank is often too low or too high to cause unstable operation of the unit, resulting in large changes in the load of the condenser, unstable system, low-voltage protection or repeated startup of the unit Phenomenon. Contents of the invention [0003] In view of this, the present invention provides a heat pump system control method, a heat pump system and an air conditioner that can...
