Title:
AIR CONDITIONING SYSTEM
Document Type and Number:
Japanese Patent JPS53104936
Kind Code:
A
Abstract:
An air conditioning system for an enclosed space which includes a compressor and expander having inlet and outlet ports with a primary heat exchanger connected between the compressor outlet port and the expander inlet port and a secondary heat exchanger connected between the expander outlet port and the compressor inlet port to complete a closed loop having a charge of air, one of the heat exchangers being thermally coupled to the enclosed space. A pump is provided for injecting air into the loop to increase the pressure therein thereby to increase the heat rate of the system. Preferably the pump is used for both injecting air into the loop and bleeding air from the loop under the control of a thermostat for maintenance of a set temperature; however, a simplified form of the invention employs constant bleed. In a more elaborate form of the invention pressure follow-up is incorporated in the control to avoid any tendency toward overshoot.
