The present invention relates to a gas heat pump system. A gas heat pump system according to one embodiment of the present invention comprises: a compressor for compressing a refrigerant; a gas engine for driving the compressor; a mixer for mixing air and fuel to generate a mixed gas to be supplied to the gas engine; a mixed gas supply line connected between the mixer and the gas engine; and a supercharger for supercharging the mixed gas supplied to the gas engine through the mixed gas supply line, wherein the supercharger comprises a sealed housing formed by sealing the remaining parts thereof other than an inlet port and an outlet port through which the mixed gas moves into and out of the housing, and a bypass line is provided between the sealed housing and the inlet port of the supercharger so as to resupply a mixed gas in the sealed housing to the inlet port of the supercharger. Therefore, the system can prevent a safety-related accident resulting from the leakage of the mixed gas out of the supplier and can reduce the amount of fuel consumption.

A cooler reduces size increase. The cooler includes a main container including a refrigeration compartment, and a battery mount set including a first battery mount to which a first battery is attachable and a second battery mount to which a second battery different from the first battery is attachable. The first battery mount and the second battery mount are positioned relative to each other to cause the second battery to be unattachable to the second battery mount when the first battery is attached to the first battery mount and to cause the first battery to be unattachable to the first battery mount when the second battery is attached to the second battery mount.

The air conditioning system with solar-powered subcooling system includes a main cooling system having an evaporator, a compressor, a condenser, and an expansion valve configured to operate in a conventional vapor compression refrigerant cycle. The subcooling system includes a compressor, a condenser, and an expansion valve, the compressor being powered by at least one rechargeable battery connected to a photovoltaic solar panel. The main system and the subcooling system are linked by a heat exchanger having a primary coil in the main system between the condenser and the expansion valve and a secondary coil in the subcooling system disposed between the expansion valve and the compressor. The main system and the subcooling system may use the same type of refrigerant, or different refrigerant types. The additional cooling provided to the refrigerant in the main system by subcooling increases the efficiency of the air conditioning system.
