A heat recovery variable-frequency multi-split heat pump system and a control method thereof. The system comprises an outdoor unit and at least two indoor units. The system is a three-pipe heating recovery multi-split heat pump system designed on the basis of a four-way reversing valve, and one indoor unit thereof is provided with two electronic expansion valves and two heat exchangers so that any indoor unit in the system can operate independently under three working conditions of refrigeration, heating or heat recovery dehumidification. Under multi-split condition, the system can operate under six working conditions, namely, the full-refrigeration working condition, the full-heating working condition, the common-heat-recovery working condition, the common-heat-recovery-dehumidification working condition, the heat recovery dehumidification-refrigeration-combination working condition and the heat recovery dehumidification-heating-combination working condition. Under the heat recovery dehumidification condition, a lower outlet air temperature, during low-temperature dehumidification, is raised by means of heat removal of a condenser so as to achieve the purpose of dehumidification without temperature fall or temperature rise, so that the thermal comfort and efficiency of the system are improved, and the refrigerating capacity and heating capacity of the system are effectively improved.

摘要:
A conduit is processed for installation in a heat exchange system as an expansion. In particular, the conduit is crushed to modify one or more flow parameters of the invention. The crushing of the conduit is preformed according to one or more crush parameters determined to ensure that refrigerant flowing through the conduit within the heat exchange system will experience a pressure drop of a predetermined amount while travelling through the conduit.
