から排出される廃ガスや廃水が保有する熱を利用するよ
うにしたものが知られている。(Prior art and its problems) Heat pumps that are operated throughout the year are known to use the heat held in waste gas and waste water discharged from factories as a heat source.
しかし、このヒートポンプは工場内又はその近傍にしか
設置できない。However, this heat pump can only be installed inside or near a factory.
また、海水や河川水を熱源として利用するヒートポンプ
も提案されたが、これも設置場所に制約を受けるのみな
らず河川水を利用する場合には水利権の制約を受けると
ともに渇水期に水量を確保するのが難しいという問題が
あった。Heat pumps that use seawater or river water as a heat source have also been proposed, but these are also subject to restrictions on installation location, and if river water is used, there are restrictions on water rights and securing water volume during dry periods. The problem was that it was difficult to do.
そこで、大気を熱源として利用するものが提案されたが
、これは大気の熱容量が水に比し格段に小さいため、隙
備費が嵩むのみならず大気の温度や湿度が季節に応じて
太き（変化するので低温、多重時における着霜を防止す
る手段を講じなければならないという問題があった。Therefore, a method was proposed that uses the atmosphere as a heat source, but since the heat capacity of the atmosphere is much smaller than that of water, this not only increases spare costs but also increases the temperature and humidity of the atmosphere depending on the season ( There is a problem in that it is necessary to take measures to prevent frost formation at low temperatures and when multiple layers are present.
更に、上水の利用も検討されたが、これは運転経費が嵩
むという不具合があり、地下水の利用は地盤性下等を惹
起するという不具合があった。Furthermore, the use of tap water was also considered, but this had the disadvantage of increasing operating costs, and the use of groundwater had the disadvantage of causing soil deterioration.

とする汚水熱源ヒートポンプにある。(Means for Solving the Problems) In view of the above, the present invention is aimed at solving the problem that even in urban areas, raw sewage, which can be obtained easily and in large quantities, has a stable temperature of about 12°C even in winter due to urban waste heat. This was done by focusing on the fact that it was discarded without being used.
The gist of this is that, in a heat pump consisting of a compressor, a four-way switching valve, a user-side heat exchanger, a throttling device, and a heat source-side heat exchanger, raw urban wastewater is pumped up from a settling pond to the heat source-side heat exchanger. pumps, filters,
A sewage heat source heat pump is characterized in that it is connected to a raw sewage supply system consisting of a heat source water tank and the like.

冷却する。(Function) Since the present invention has the above configuration, raw sewage of urban wastewater is pumped up from the settling basin by a pump,
The refrigerant is supplied to the heat source side heat exchanger through a filter, a heat source water tank, etc., where it heats or cools the refrigerant by exchanging heat with the refrigerant.

経て圧縮機１に再び吸入される。During cooling operation, the refrigerant gas discharged from the compressor 1 passes through the four-way switching valve 2 and enters the heat source side heat exchanger 5, as shown by the solid line arrow, where it enters the raw sewage supplied through the raw sewage supply system. Condenses and liquefies by dissipating heat. This refrigerant liquid passes through the check valve 7b and the liquid receiver 6 and enters the cooling expansion valve 4a, where it is throttled and adiabatically expanded. Next, this refrigerant enters the user-side heat exchanger 3, where it evaporates and vaporizes by cooling the cooling water. Then, it is sucked into the compressor 1 again through the four-way switching valve 2.

ことにより昇温した後、放水路１５に排出される。On the other hand, the raw sewage stored in the settling basin 9 is pumped up by a pump 10, and in the process of flowing through a filter 11, bulky garbage contained in the raw sewage is removed, and then it is temporarily stored in a heat source water tank 12. Next, it is extracted by the pump 13 and enters the heat source side heat exchanger 5, where it is heated by absorbing heat from the refrigerant, and then discharged to the discharge channel 15.

。そして、四方切換弁２を経て圧縮機ｌに戻る。During heating operation, the four-way switching valve 2 is switched, so
The refrigerant gas discharged from the compressor 1 passes through the four-way switching valve 2 and enters the user-side heat exchanger 3 as shown by the dashed arrow, where it condenses and liquefies by heating hot water for heating. Then, this refrigerant liquid passes through the check valve 7a and the liquid receiver 6 and enters the heating expansion valve 4b, where it is throttled and adiabatically expanded. Next, this refrigerant enters the heat source side heat exchanger 5, where it evaporates by absorbing heat from the raw sewage. Then, it returns to the compressor l via the four-way switching valve 2.

きる。Therefore, in the summer, the atmospheric temperature is about 35° C., while the temperature of raw sewage is about 25° C., so the power cost in the summer can be reduced by about 32% compared to when the air is used as the heat source.
また、冬季においては大気温度は約θ℃であるのに対し
生下水の温度は都市排熱によって昇温していて約１２℃

勿論である。In addition, in winter, the atmospheric temperature is approximately θ℃, while the temperature of raw sewage increases by approximately 12℃ due to urban exhaust heat.
In the above example, the power cost in winter can be reduced by about 26% compared to when using the atmosphere as a heat source.
Although the heat pumped up by the heat pump is used for cooling and heating, it is of course possible to use it for any other purpose.

も生じない。Since raw sewage maintains a stable temperature of about 12°C in winter and about 25°C in summer, power consumption can be significantly reduced compared to systems that use the atmosphere as a heat source. Furthermore, no defrosting means is required, and the heat exchanger on the heat source side is small, so equipment costs can be reduced. Furthermore, since raw sewage can be easily used in large quantities in urban areas, heat pumps can be installed in urban areas, and therefore it is easy to use the heat pumped up by the heat pumps. Moreover, various problems that occur when using seawater, river water, tap water, and groundwater do not occur.
