In the cold and severe cold regions of our country, the average temperature in winter outdoor usually below -20°C. Air conditioning units was limited and damaged when it running under such conditions. In order to solve the the problems pointed out previously, the paper put forward solutions of the fresh air handling units in combination with heat pump unit of heat recovery fresh air and heat pipe heat pump low temperature heat recovery unit. Comparison energy-saving and recovery period of the two method through experimental research.
