Application of an open-type heat-source tower in the heat pump system

A new installation called the open-type heat-source tower was introduced and its structural features and principle of operation were analyzed in this paper.Its applicability,status quo and prospects of application in heating,ventilation and air-conditioning(HVAC)systems were discussed.It was concluded from the analysis that the open-type heat-source tower can be used as the heat source of the air-conditioning system in winter and as the cold source in summer.With this dual-purpose installation,the purposes of comprehensive utilization of resources and reducing of energy consumption can be attained.This new technology will be applicable especially in the south of China.It could effectively solve the problem of frost formation in the air-source heat pump running in winter and substitute for the ground-source heat pump which are used limitedly in those regions.
