本発明は外気を熱源とするエンジン駆動ヒートポンプ装
置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an engine-driven heat pump device that uses outside air as a heat source.
エンジンで圧縮機を駆動するヒートポンプはエンジンの
シリンダー冷却熱および排ガス熱を回収利用できること

。以下路ｔＳを参照しながら従来の技術と問題点を説明
する。Heat pumps, which use an engine to drive a compressor, can recover and use the engine's cylinder cooling heat and exhaust gas heat, so they have an even greater energy-saving effect than electric heat pumps, and are being put into practical use and widespread use in Japan and West Germany. The conventional technology and problems will be explained below with reference to the road tS.

ー冷却熱を吸収し、さらに排ガス熱交換器（ＩＩで排ガ
ス熱を吸収して昇温されてから温水タンクに戻る。The refrigerant (1) compressed by the compressor (2) driven by the engine (1) passes through the refrigerant (3), the JLL expansion valve (4), and the evaporator (5), and then enters the 1kR refrigeration cycle. Form. As a heat source for evaporating the refrigerant in the evaporator, outside air drawn in by a fan (6) driven by the engine is used. - Hot water (b) in the hot water tank (7) is pumped by the pump (8), absorbs the condensation heat of the refrigerant in the condenser, and then absorbs the cylinder cooling heat in the engine cylinder cooling section (9). Then, the exhaust gas heat is absorbed by the exhaust gas heat exchanger (II) and the temperature is raised before returning to the hot water tank.

もそれ以上大自な容量を持つ補助ボイラー装置を設置し
て、外気温が低下し九と含にはヒートポンプ装置の運転
を中止して補助ボイラーの運転に切り換えねばならない
という欠点があった。A toto pump with this type of configuration has the feature of being able to utilize as much as 150-180% of the heat of the primary energy (energy in the engine fuel), but on the other hand, when the outside temperature drops (for example, below 5 degrees Celsius), the evaporator There was a drawback that moisture from the outside air landed on the surface until frost formed, making it impossible to operate. Moreover, when the outside temperature drops, the heating load increases, so even if a heat pump device is installed, an auxiliary boiler device with a larger capacity has been installed, and when the outside temperature drops, the heating load increases. There was a drawback that the operation of the heat pump device had to be stopped and the operation of the auxiliary boiler had to be switched over.
本発明の目的はこのような従来の欠点を考１してなされ

のである。The object of the present invention is to take into account the drawbacks of the conventional art. - The aim is to make the heat pump device capable of operating even when the outside temperature drops, so that even if an auxiliary boiler is installed, its capacity will be small. In other words, when the outside temperature drops, the engine exhaust gas is not used to raise the temperature of hot water, but the outside air is heated with the heat of the high-temperature exhaust gas in order to prevent frost formation and water landing in the nuclear power plant.
It is.

排ガス熱交換器内を流れる。FIG. 2 shows one embodiment of the present invention, in which the exhaust gas exiting the exhaust gas heat exchanger αQ is guided to the exhaust gas discharge pipe α- disposed in front of the evaporator (5). A large number of exhaust gas discharge holes are open in the exhaust gas discharge tube, and the exhaust gas (d) flows out from the exhaust gas discharge tube, mixes with the outside air sucked in by the fan (6), and heats up the air. The hot water flow path is provided with a bypass (14) and a three-way valve α9, and when the outside temperature drops, the hot water flows through the bypass α9 without flowing through the gas heat exchanger α. When there is no longer any risk of frost or water landing in the evaporator, the three-way valve is activated and the hot water flows through the exhaust gas heat exchanger again.

要はない。Next, the effects of the present invention will be explained. In Figures 2 and 3, the three-way valve α$ operates and the hot water (b) enters the bypass α
4, the exhaust gas temperature does not decrease because heat exchange is not performed at the exhaust gas heat exchanger α value, and therefore the pigeon temperature (approximately 60
Since the exhaust gas remains at 0 (0) and increases the temperature of the outside air that is sucked into the evaporator, it is now possible to operate even when the outside temperature drops to such a low level that in the past it was impossible to operate due to frost formation or water splashing. Yes, even if you install an auxiliary boiler, it only needs to have enough capacity to supplement the capacity of the heat pump, so there is no need to install one that exceeds the capacity of the heat pump, unlike in the past.
