Research on improving the condenser and evaporator capacity of air source heat pump
In order to improve the transfer capacity of air source heat pump,the factors affecting the capacity of heat pump are discussed and studied.Under certain design conditions,the structure,materials,heat transfer characteristics and the flow mode of hot and cold fluid of the two units of the contemporary heat pump system are analyzed and studied to ensure the optimization of the capacity of the two units.The shape of the micro-channel,the placement angle of the micro-channel and different kinds of refrigerants are studied in detail.Finally,under the condition of ensuring the stability of system working condition,the heat pump system is fully debugged through orthogonal test,and the optimal parameter combination is given.
