イン運転のみをも可能にしたことを特徴とする。 Conventionally, this type of air-conditioning water heater uses the condensation heat of an outdoor heat exchanger to obtain hot water.
For example, there is Japanese Patent Publication No. 57-43830, whose circuit diagram is shown in Figure 2. According to this, an outdoor unit 1 includes a compressor 7, an air-cooled outdoor heat exchanger 4, an outdoor fan 6, and a water-cooled The water-cooled outdoor heat exchanger 5, which includes an outdoor heat exchanger 5, electrical components (not shown), etc., the circulation system, and a hot water tank 8 serving as a heat storage tank;
It consists of a hot water supply line 3 consisting of a hot water supply line 9, an indoor heat exchanger, an indoor unit 2 containing an indoor fan, etc. When the hot water supply line 3 is not in operation, an air-cooled outdoor heat exchanger 4 is connected to the hot water supply line 3. During operation, the three-way valve 11 is switched to utilize each of the water-cooled outdoor heat exchangers 5 for cooling operation. However, when the hot water supply line 3 is operated, the water-cooled outdoor heat exchanger 5 is used and the air-cooled outdoor heat exchanger 4 is not used, so it is recommended that the outdoor fan 6 attached to the air-cooled outdoor heat exchanger 4 not be operated. As a result, heat builds up inside the outdoor unit 1 due to the heat generated by the operation of the compressor 7, and the temperature becomes higher than the guaranteed heat resistance temperature of the electrical components inside the outdoor unit 1.
There is a drawback that the durability of electrical components deteriorates, and in this conventional example, cooling operation and heating operation (both air-cooled heat exchanger 4 and indoor unit 2
(1), hot water supply operation (between the water-cooled heat exchanger 5 and indoor unit 2) can only be performed while cooling, and hot water supply operation cannot be performed, which is inconvenient.
The present invention was devised in view of the above-mentioned conventional deficiencies.The purpose of the present invention is to operate an outdoor fan in a cooling and hot water supply system when the hot water supply line is running while cooling the air, so that the electrical components inside the outdoor unit can be operated. This invention not only improves the durability of the compressor but also enables operation only for hot water supply.
The above-mentioned air-cooled unit is equipped with an outdoor unit containing an air-cooled outdoor heat exchanger, an outdoor fan, electrical components, etc., a water-cooled outdoor heat exchanger, a hot water supply line containing water as a heat exchange medium, and an indoor unit. A refrigeration system capable of cooling operation, in which the outdoor heat exchanger, the water-cooled heat exchanger, and the indoor unit are switchable, and the air-cooled outdoor heat exchanger 4 and the indoor unit 2 are connected to the compressor 7. A refrigeration circuit that connects the compressor 7 to a water-cooled outdoor heat exchanger 5 and an indoor unit 2 and is capable of operating a cooling and hot water supply line 3; It is possible to selectively form three refrigeration circuits in which the hot water supply line 3 formed by connecting the heat exchanger 5 and the air-cooled outdoor heat exchanger 4 can be operated, and the cooling and hot water supply line 3 can be operated. Provided is a cooling water heater in which the outdoor fan is operated continuously or intermittently when a refrigeration circuit capable of It is characterized by being able to operate only the hot water supply line.

可能にする。 Fig. 1 is a diagram showing an outline of the circuit of the cooling water heater of the present invention (the same parts as in Fig. 2 are given the same reference numerals), in which 1 is an outdoor unit, a compressor 7, an air-cooled outdoor heat exchanger, 4, outdoor fan 6, other four-way valves,
It has a built-in three-way valve, an accumulator, electrical components, etc. (all not shown), and 2... is an indoor unit that has a built-in indoor heat exchanger and an indoor fan (not shown).
is a hot water supply line, which includes a water-cooled outdoor heat exchanger 5, a water supply line 10 ball tap, etc. built into the hot water tank 8, and a hot water supply line 9 from the hot water tank 8 to the outside, which connects the compressor 7 and air cooling. The refrigerant circuits of the outdoor heat exchanger 4 and the water-cooled outdoor heat exchanger 5 can be switched by a three-way valve, and these and the indoor unit 2 are also connected by a known refrigerant circuit. Cooling operation is possible using a refrigeration circuit that uses either the heat exchanger 4 or the water-cooled outdoor heat exchanger 5 as a condenser, and heating operation is possible using a heat pump operation by switching the four-way valve. During cooling operation in which the outdoor heat exchanger 5 acts as a condenser, the hot water supply line 9 is connected to the refrigeration circuit that heats the water in the hot water tank 8 using condensation heat.
The hot water line can be operated while cooling, and when neither cooling nor heating is required, the refrigerant to the indoor unit 2 is cut off by known means, and the refrigeration circuit between the outdoor unit 1 and the hot water supply line 3 is operated to supply hot water. It is now possible to operate only the line. In this case, the refrigeration circuit is formed as a circulation circuit in which the refrigerant passes from the compressor 7 through the water-cooled outdoor heat exchanger 5 to the air-cooled outdoor heat exchanger 4 and returns to the compressor 7 again. The air-cooled outdoor heat exchanger 4 in the outdoor unit 1 acts as an evaporator, while the water-cooled outdoor heat exchanger 5 in the hot water supply line 3 acts as a condenser, and the condensed heat is transferred to the hot water tank 8. Only the hot water supply line 3 can be operated by heating the water.

（何れも図示せず）されている。 Therefore, during the hot water supply line operation during the cooling operation, the water-cooled outdoor heat exchanger 5 is not used.
Therefore, normally the outdoor fan 6 in the outdoor unit 1 would be stopped, but the feature of the present invention is that the outdoor fan 6 can be operated continuously or can be stopped for a short time by a timer or a thermostat that detects the temperature inside the outdoor unit 1. It is electrically wired (none of which is shown) so that it can be operated.

ば良く、冷房兼給湯運転可能にすれば良い。 In the above example, the water-cooled outdoor heat exchanger 5 was built in the hot water tank 8, but as shown in FIG. Cooling water may be circulated between the hot water tank 8 and the indoor unit 2, and there may be one or more indoor units 2. Various known means may be used for the air conditioning, heating, and hot water supply circuits, and heating operation may be added as appropriate. All you have to do is make it possible to operate the system for both cooling and hot water supply.

変更が可能となるなどの効果がある。 The present invention is as described above, and the outdoor fan 6, which was conventionally stopped, is now operated when the water-cooled outdoor heat exchanger 5 is operated as a condenser in the hot water supply line 3, especially during cooling operation. Therefore, the heat generated by the compressor 7 is not trapped inside the outdoor unit 1 and is dissipated, so the ambient temperature around the electrical equipment is lowered, each part of the electrical equipment is always maintained at an appropriate temperature, and each electrical equipment The parts are protected and the durability is significantly improved compared to the conventional method, and it goes without saying that intermittent operation using a timer or thermostat can save power. In addition, the cooling water heater of the present invention only has a cooling operation using the air-cooled heat exchanger 4, and a water-cooled outdoor heat exchanger 5.
It is now possible to operate the hot water supply line 3 while cooling the air using the air-cooled heat exchanger 4, and to operate the hot water supply line 3 using the air-cooled heat exchanger 4 as an evaporator and the water-cooled heat exchanger 5 as a condenser. This is practical because only hot water can be supplied when the cooling operation is stopped, and when heating is required, the design can be easily changed by adding known means so that the heat pump can be operated.
