Application analysis of three heat recovery methods in laboratory animal rooms

The advantages and disadvantages of heat pipe heat recovery, glycol heat recovery and heat pump heat recovery suitable for exhaust heat recovery of laboratory animal rooms are presented. The meteorological parameters of the equilibrium point of the heat recovery and power consumption of the three heat recovery methods are calculated respectively. Combined with an laboratory animal room in Wuhan, the annual recovery energy and investment payback periods of the three heat recovery methods are calculated. It is concluded that the heat pump heat recovery is more suitable for laboratory animal room energy recovery in hot summer and cold winter zone.
