Title:
【発明の名称】熱的インター・クーラー
Document Type and Number:
Japanese Patent JPH05502501
Kind Code:
A
Abstract:
A non-restrictive, constant pressure refrigerant recycling and cooling unit that interrupts the normal refrigerant cycle to permit a lower temperature liquid to enter the expansion device, and thus provide a lower temperature, and therefore a lower pressure gas for delivery to the inlet side of the compressor, which acts to reduce the energy requirement and cost to operate the compressor. This reduction in pressure and temperature also results in lower operating costs and lower maintenance costs and utilizes less refrigerant quantity requirements. A key factor in attaining the above advantages is the construction of the thermal inter-cooler that is so made that no restrictions are specifically inserted in the inter-cooler system, and that direct physical contact exists between the metal compressor inlet suction line and the metal (Cu) refrigerant hot line for optimum heat transfer, and as a result an increased volumetric efficiency and increased capacity occurs by a lowering of the pressure on both sides of the compressor.
