COOLING APPARATUS FOR AUTOMOTIVE SEATS

摘要

PURPOSE: A seat cooling device for a vehicle is provided to improve the cooling efficiency for a seat for a vehicle by using the refrigerant for vehicle conditioning. CONSTITUTION: A seat cooling device for a vehicle comprises a refrigerant circuit(10) for seat cooling. The refrigerant circuit is connected to the main refrigerant circuit(1) of an air conditioning device for a vehicle. The refrigerant circuit for seat cooling comprises an expansion valve for cooling a seat(11), a plurality of evaporators for cooling a seat(14), and a controller(15). The expansion valve for cooling a seat reduces the pressure of the liquefied refrigerant by a main refrigerant circuit. The evaporators for cooling a seat cools the seat by using the pressure reduced refrigerant for heat exchanging. The controller controls the operation of the expansion valve for seat cooling.
