Gas heat pump type air conditioning device

Abstract

In order to provide a gas heat pump type air conditioning device in which accessibility and maintenance operation are not disturbed due to snow in snowy areas, a gas heat pump type air conditioning device comprises a compression device for which the driving source is a gas engine and forms a refrigerating cycle by circulating a refrigerant, a bypass pipe channel section which is provided around space where an outdoor unit is installed and is separated from an engine-coolant-water system of the gas engine via a channel change switching device, wherein waste heat exhausted from the gas engine is collected back into the engine-coolant-water, and the refrigerant is heated by the engine-coolant-water so as to enhance air heating capacity.

What is claimed is:  
     
         1 . A gas heat pump type air conditioning device comprising: 
 a compression device having a gas engine driving source and forming a refrigerating cycle by circulating a refrigerant;    a bypass pipe channel section which is provided around a space where an outdoor unit is installed and is divided from an engine-coolant-water system of the gas engine via a channel change switching device;    wherein waste heat exhausted from the gas engine is collected back into the engine-coolant-water, and the refrigerant is heated by the engine-coolant-water so as to enhance air heating capacity.    
     
     
         2 . A gas heat pump type air conditioning device according to  claim 1 , wherein the bypass pipe channel section is divided after the refrigerant is cooled by the engine coolant water.  
     
     
         3 . A gas heat pump type air conditioning device according to  claim 1 , wherein a heating device which heats exhaust gas which is exhausted from the gas engine and increases the amount of thermal energy collectable in an exhaust gas heat exchanging device.  
     
     
         4 . A gas heat pump type air conditioning device according to  claim 3 , wherein the heating device is a combusting device for heating exhaust gas which supplies the exhaust gas generated by combusting fuel in the combusting device to the exhaust gas.  
     
     
         5 . A gas heat pump type air conditioning device according to  claim 4 , wherein the combusting device of the combusting device for heating exhaust gas is provided in the exhaust gas heat exchanging device.  
     
     
         6 . A gas heat pump type air conditioning device according to  claim 4 , wherein a catalyst container which contains exhaust gas cleaning catalyst is provided in a exhaust system which connects the gas engine and the exhaust gas heat exchanging device, and a combustor of combusting device for heating exhaust gas is provided in the catalyst container.  
     
     
         7 . A gas heat pump type air conditioning device according to  claim 1 , wherein the bypass channel which is provided with the channel change switching device in the engine coolant water system in the downstream of the gas engine is formed, and the engine coolant water heating device is provided in the bypass channel.  
     
     
         8 . A gas heat pump type air conditioning device according to  claim 4 , wherein the heating device combusts the same gas fuel as the gas engine and heats the gas fuel.  
     
     
         9 . A gas heat pump type air conditioning device according to  claim 3 , wherein the heating device operates when outdoor air temperature detecting device ( 74 ) detects temperature lower than a predetermined value.
