Abstract
"Condensing Units" consists of a compressor and condenser and can be used in combination with various evaporator units such as display-case type refrigerators and cooling coils for cold storage. Many of these units are installed in food retail stores of supermarkets and convenience stores, which carries the problems that condensing units consume more than half of the entire electricity demand of the whole stores. Gas engine condensing units (GCU) are developed using GHP (Gas Engine driven Heat Pump) technologies, which have the same characteristics as GHPs. The compressor of the GCU is driven by a natural gas engine, thus requiring little electricity and therefore solving the electricity problem in the stores. The GCU can reduce not only energy costs but CO2, NOX and SO2 emissions compared with conventional systems because of the cleanliness of natural gas.
