WebConductance Heat Pipe (CCHP), it is wise to start with the layout of a CCHP. There are three sections of a basic heat pipe with a working fluid enclosed inside the pipe. Various fluids are used in heat pipes and the selected fluid is based upon its saturation temperature and the temperature at which the heat pipe will be functioning. WebCold-climate heat pump (CCHP) is the latest development of high-efficiency air source heat pump design, which is mainly used to solve the heating problem in cold areas. Thanks to the inverter or variable speed drive compressor design, these heat pumps can achieve high efficiency even in winter.
