Problems solved by technology

[0004] 1. Increasing the amount of refrigerant charge can certainly solve the problem of insufficient operating refrigerant under certain conditions, but the excessive charge of refrigerant will bring potential safety hazards to the system. When there is no accumulation of refrigerant in some cycles, It will cause too much circulating refrigerant in the system, which will easily cause liquid shock and damage the compressor
In order to avoid too much refrigerant, it is necessary to increase the liquid storage tank, which increases the complexity and cost of the sy

Abstract

A heat pump system and a method for starting a heat pump system are provided. The method comprises: receiving a start instruction; controlling the heat pump system to enter a start mode according to the start instruction; recycling refrigerant in the heat pump system under the start mode; determining whether the start mode is completed; and if yes, controlling the heat pump system to enter an operation mode.

Description

Technical field [0001] The invention relates to a heat pump system and a startup control method thereof. Background technique [0002] With the development of heat pump technology, more and more heat pump products are put on the market, the functions of heat pump products are becoming more and more abundant, heat pump systems are becoming more and more complex, and the number of heat exchangers used is increasing. For example, a multi-unit air conditioner has multiple indoor heat exchangers. In addition to the air heat exchanger, the air source heat recovery air conditioner water heater also has a hot water heat exchanger for air and water. When multiple heat exchangers are not used at the same time, there will be refrigerant stored in the unused heat exchanger, which will cause changes in the amount of refrigerant participating in the system cycle. If not controlled, it will seriously affect the safety of the system run. Therefore, improving the utilization rate of refrigerant...
