合を有する。[Detailed Description of the Invention] The present invention relates to an engine-driven air conditioning system.
Conventionally, as a device of this kind, a device is known in which a waterproof engine or the like is immersed in a water tank to prevent noise (Japanese Utility Model Publication No. 57-26102). Such a device is not only expensive due to its waterproof structure, but also tends to corrode the main body of the engine, etc. due to the water in the water tank, so noise can be prevented by housing the engine, compressor, etc. inside a soundproof case. The formula can be considered. In such a case, since the structure is sealed except for the intake and exhaust ports communicating with the combustion chamber of the engine, the temperature inside the soundproof case increases, which is likely to damage the electric motor used to start the engine.

る。 An object of the present invention is to provide a device that eliminates such inconveniences, and includes at least a compressor 1 that compresses refrigerant, an engine 2 that drives the compressor 1, and an electric motor 3 that starts the engine 2.
and a part of the circulation pipe 4 through which the coolant of the engine 2 circulates are housed inside the soundproof case 5, and an intake duct 7 communicates from the combustion chamber 6 of the engine 3 to the outside of the soundproof case 5. It is characterized in that an exhaust pipe 8 is provided, and an on-off valve 10 that opens and closes by sensing the temperature inside the soundproof case 5 is provided in a communication portion 9 of the intake duct 7 that communicates with the inside of the soundproof case 5.

湯管である。 The illustrated one includes a circulation pump 11 that circulates liquid, and a heat absorber 1 that absorbs cooling heat from the engine 2.
2, and an exhaust heat recovery device 13 that recovers exhaust heat after combustion.
, a radiator 17 equipped with a heater 15 that heats the water in the hot water storage tank 14, and a blower 16 that is turned on when the water temperature in the hot water storage tank 14 rises above a set temperature.
A liquid circulation circuit 22 was constructed. Reference numeral 18 denotes a filter, and the intake air that has passed through the filter 18 passes through the intake valve 19 and reaches the combustion chamber 6. After being mixed with gas, it is ignited by a known ignition means to cause explosive combustion, and a piston (not shown) is fired. A shaft 23 output is generated through the shaft 23. The exhaust gas after combustion is released through exhaust valve 2.
The exhaust heat is heated from 0 to the exhaust heat recovery device 13 and discharged from the silencer 21. The refrigerant compressed by the compressor 1 by the output of the shaft 23 transmitted via the belt 24 etc. is cooled and heated indoors by a known refrigerant circuit composed of a four-way valve, an indoor unit, an outdoor unit, etc. (not shown). It's summery. Reference numeral 25 denotes a temperature sensing element, and when the temperature inside the soundproof case 5 is higher than the set temperature of the temperature sensing element 25, the on-off valve 10 is opened and hot air is forcibly sucked in by the suction pressure of the intake duct 7. The temperature drop inside the valve was measured, and the valve was configured to close when the temperature drops below the set temperature. Note that 26 is a water supply pipe and 27 is a hot water outlet pipe.

できる効果を有する。 As explained above, according to the present invention, an on-off valve 10 that opens and closes by sensing the temperature inside the soundproof case 5 is provided in the communication part 9 of the intake duct 7 that communicates with the inside of the soundproof case 5. Since the internal temperature is kept constant at, for example, 50 degrees Celsius to 60 degrees Celsius, a heat pipe or the like is used to cool the inside of the soundproof case, and a part of the refrigerant circuit is guided inside the soundproof case for evaporation. Compared to the cooling method, it has a simpler structure and has the effect of reliably preventing the above-mentioned disadvantages.
