ガスヒートポンプ式空気調和機を用いた系統連系システム
Document Type and Number:
Japanese Patent JP5478959
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize high energy consumption efficiency by reducing a conversion loss in a system-interconnected inverter.SOLUTION: This system-interconnected system includes a gas heat pump system of air conditioner 1 which includes a gas engine 10 for driving a compressor 12 and a generator 30, an AC/DC converter 34 which converts AC power generated by the generator, a system-interconnected inverter 40 which converts this output power into the AC power of a commercial system 44 to which the air conditioner 1 is connected, and an interconnected relay 48 which controls whether to return the AC power to the commercial system 44 or not. It includes a feed control relay 49 which is connected to the auxiliary machine of the air conditioner to be fed with power of the AC/DC converter by the system and controls whether to feed the auxiliary machine by a commercial system or not.
