Title:
電力供給された過冷却器を備えるHVACシステム
Document Type and Number:
Japanese Patent JP2008530498
Kind Code:
A
Abstract:
An HVAC system having a main circuit and a subcooler circuit. The main circuit includes a main circuit evaporator, a main circuit expansion device, a main circuit condenser and a main circuit compressor connected in a closed refrigerant loop. The subcooler circuit includes a subcooler evaporator, a subcooler expansion device, a subcooler condenser and a subcooler compressor connected in a closed refrigerant loop. The subcooler evaporator is arranged and disposed to exchange heat between liquid refrigerant in the main circuit and the refrigerant in the subcooler circuit to cool the liquid refrigerant in the main circuit prior to entering the main circuit evaporator. The operation of the subcooler circuit provides an increased cooling capacity per unit of a mass flow of cooling fluid through the main circuit condenser and subcooler condenser for the HVAC system with a predetermined design efficiency.
