Figure 1 shows a conventional system, where 1 is a compressor and 2 is a compressor.
3 is a secondary hot water heat exchanger, 3 is a primary hot water heat exchanger/condenser, and here is a so-called double handle type in which a water chamber separates the tube group that uses cooling water and the tube group that uses hot water. Although the primary hot water heat exchanger and condenser may be independent, in this case both hot water heat exchangers are provided between the compressor and the condenser. Although a water-cooled condenser is shown, an air-cooled condenser may also be used. 4 is an evaporator, 5 is an expansion valve, 6 is a hot water supply pump, 7 is a hot water storage tank, 8 is a primary hot water supply water inlet pipe, 9 is a primary hot water supply water outlet and secondary hot water supply water inlet pipe, 1
0 is a secondary hot water supply water outlet pipe, 11 is an electric or steam heater, and 12 is a water supply faucet to the user. Figure 2 shows the above device in a Mollier diagram, and hot water is supplied to the secondary hot water heat exchanger. In 2, heat is exchanged with the sensible heat part B of the refrigerant gas discharged from the compressor, and in the primary hot water supply heat exchanger and condenser 3, heat is exchanged between the sensible heat part and the latent heat part A of the refrigerant.

Ideally, the hot water outlet temperature of the hot water supply section of the primary hot water heat exchanger and condenser 3 should be taken out at a temperature corresponding to the condensation temperature CT, and the temperature of the hot water outlet of the secondary hot water heat exchanger 2 outlet is also compressed. Ideally, the gas should be taken out at a temperature equivalent to the machine discharge gas temperature T 0 , but although it is possible to get closer to the ideal by increasing the heat transfer area of any heat exchanger, it will result in a significant cost increase. This is not a good idea. To explain with specific numerical values, when Freon 22 is used as a refrigerant,
Condensing temperature CT = 46℃, primary hot water inlet temperature = 7℃,
Primary hot water supply water outlet temperature = 43~44℃, secondary hot water supply water outlet temperature = 50~55℃, compressor discharge gas temperature T 0 = 70~
The temperature is around 75℃. Since the temperature of the cooling water in the refrigerator changes depending on the load fluctuation or the season, it is not always possible to maintain the above-mentioned hot water supply temperature. Therefore, if the hot water storage tank 7 is equipped with an electric heater or a steam source, steam is used for supplementary heating in order to bring the hot water to a temperature that the user can use satisfactorily.

In other words, in the conventional system, it was necessary to appropriately increase the heat transfer area of the primary water supply heat exchanger and the secondary water supply heat exchanger, and to perform auxiliary heating if the temperature required by the user could not be obtained.

Install a heat exchanger,
The piping is connected so that the hot water supply flows through the primary hot water heat exchanger and the secondary hot water heat exchanger in that order, and the hot water taken out from the secondary hot water heat exchanger passes through the hot water storage tank and is then supplied from the primary hot water heat exchanger. Abstract: A refrigeration system characterized by being provided with a recirculation hot water pipe that joins water and guides it to the inlet side of the secondary hot water heat exchanger for recirculation, and a recirculation pump in the hot water pipe. By using the above configuration, the hot water supply water is recirculated to the secondary hot water heat exchanger, so hot water at a higher temperature can be obtained.
No auxiliary heat source is required, and the heat transfer area of the hot water heat exchanger can be made small, making it compact and inexpensive.

According to the above configuration, the hot water that exits the primary hot water heat exchanger 3 passes through the piping 9, enters the secondary hot water heat exchanger 2, exchanges heat with the high temperature refrigerant gas discharged from the compressor 1, and is further heated to a higher temperature. hot water is stored in the hot water storage tank 7 via the piping 10. This stored hot water is circulated again through the secondary hot water heat exchanger 2 through the piping 15 by the pump 13, and is heated until it approaches the refrigerant gas temperature T 0 shown in FIG. return. The pump 13 is operated by a temperature switch 14 installed in the hot water storage tank 7 until a desired temperature is obtained.
