Engine driven heat pump

Abstract

Regarding an engine driven heat pump in which an engine, a compressor, a refrigerant circuit, and a generator are stored in a main body package, an engine actuation battery to actuate the engine, a battery charging circuit to charge the engine actuation battery, and an inverter to convert output power from the generator into a predetermined voltage and a predetermined frequency are stored in a separate body package, which is a separate body with respect to the main body package, and a front surface and a back surface of the separate body package is made up of an area in such a manner as to fit in a side surface of the main body package, and the separate body package is provided on a side surface near to the generator, out of side surfaces of the main body package and supported by the main body package.

Description

INCORPORATION BY REFERENCE REGARDING APPLICATION AND PRIORITY[0001]This nonprovisional application claims priority under U.S.C. 119(a) on Patent Application No. 2013-193236 filed in Japan on Sep. 18, 2013, the entire contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to an engine driven heat pump in which heat exchange is performed by use of a refrigerant, which is sucked and discharged by a compressor driven by an engine, thereby flowing through a refrigerant circuit.[0004]2. Description of the Related Art[0005]Conventionally, it has been known that a generator is mounted in the engine driven heat pump in which heat exchange is performed by use of a refrigerant, which is sucked and discharged by a compressor driven by the engine, thereby flowing through a refrigerant circuit (see, for example, Japanese Patent No. 4682558).[0006]Japanese Patent No. 4682558 discloses that the engine driv...

AI Technical Summary

Benefits of technology

The present invention is an engine driven heat pump, which includes a generator and is used as a power supply device in case of power failure. The heat pump includes an engine, a compressor, a refrigerant circuit, and a generator, which are all mounted on a common main body package. Additionally, there is also a separate body package that contains the engine actuation battery, the battery charging circuit, and the inverter. This separate body package is designed to fit in a side surface of the main body package and is supported by it. The engine and the generator, along with the refrigerant circuit, can be separated from each other and arranged right and left viewed from a front surface of the main body package. This mounting construction ensures that the engine driven heat pump can provide a self-sustaining power supply to the engine during power failures.

Problems solved by technology

However, although Japanese Patent No. 4682558 discloses that the engine driven heat pump, in which the generator is mounted, is used as the power supply device at the time of power failure, Patent Document 1 fails to disclose any specific mounting constitution of members constituting a self-sustaining power supply device that includes an engine actuation battery, which is required for the actuation of the engine at the time of power failure.
