Condenser in the whole working process is the process of exothermic, is the refrigeration system of the machine, can turn the gas or vapour into liquid, it belongs to a kind of heat exchanger, condensation process first low temperature and low pressure gas compression into high temperature and high pressure gas, and then through the condenser, in the machine condensed into low temperature and high pressure liquid, after the throttle valve throttle, then become low temperature and low pressure liquid. Condenser temperature are higher.
