Description

  The present invention relates to an outdoor unit of an air conditioner that is intended to reduce the heat cost to the atmosphere, which is a cause of reduction in utility costs and global warming.

  A conventional outdoor unit of an air conditioner sucks outside air in a cooling operation and heats it by a heat exchanger on the inlet side, and the heated outside air becomes hot air by a fan and is discharged from the outlet to the atmosphere.

Therefore, there were the following problems.
(A) In the cooling operation of the outdoor unit of the air conditioner, hot air discharged from the outlet increases the atmospheric temperature and is one of the causes of global warming.
(B) In the cooling operation of the outdoor unit of the air conditioner, hot air discharged from the outlet is not effectively used.
(C) Air conditioner outdoor unit fans are not used effectively.
The present invention has been made to solve these problems.

  A heat exchanger coil comprising a heat transfer pipe that snakes through a plurality of aluminum fins arranged side by side and a tap water inlet and a tap water outlet for feeding tap water into the heat transfer pipe. In addition, the control circuit can be installed in front of the outlet in a square shape, and the left and right sides of the heat exchanger coil and the top surface are surrounded by a transparent body so that only the fan of the outdoor unit can be operated by low-speed rotation independently. An outdoor unit of an air conditioner characterized in that

Compared to outdoor air conditioner outdoor units, the release of heat load to the atmosphere that causes global warming is reduced, and hot air discharged from the outdoor unit is effectively used to retreat the bathtub. It reduces the energy bills and reduces the heat load on the atmosphere.
In addition, by surrounding the left and right side surfaces and the top surface of the heat exchanger coil with a transparent body, solar heat is effectively collected in the heat exchanger coil, and the temperature of tap water inside the heat transfer tube of the heat exchanger coil is increased. Since it is used in the bathtub after a long time, it reduces the cost of reheating.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to FIGS.

The outdoor unit of the air conditioner is configured as shown in FIG.
The outdoor unit main body 1 is partitioned into a heat exchanger chamber 3 and a heat exchanger coil chamber 4 with a blowout port 2 as a boundary. The heat exchanger chamber 3 has a fan 7 that is rotated by the operation of the heat exchanger 5 and the fan motor 6, and has a compressor and a control circuit. There is a heat exchanger coil 8 in the heat exchanger coil chamber 4, and the heat exchanger coil 8 is inclined to the front surface of the blowout port 2 in a dogleg shape as shown in FIGS. 1 and 2. 9, the left and right side surfaces and the top surface of the heat exchanger coil 8 are surrounded by a transparent body 14. The heat exchanger coil 8 is configured as shown in FIG. There are a copper heat transfer pipe 11 passing through a plurality of aluminum fins 10 arranged in parallel and a tap water inlet 12 and a tap water outlet 13 for feeding tap water into the heat transfer pipe 11. With the outdoor unit 1 configured as described above, in the cooling operation, as shown in FIG. 1, the fan motor 6 is activated and the fan 7 rotates, so that the outside air advances in the direction of the arrow. The outside air is sucked into the outdoor unit and heated by passing through the heat exchanger 5, becomes hot air, and is blown to the heat exchanger coil 8. As shown in FIG. 4, in the heat exchanger coil 8, when the tap 15 is opened, tap water having a temperature lower than the outside air temperature passes through the pipe 16 and passes from the tap water inlet 12 of the heat exchanger coil 8 to the heat transfer tube 11. When water is supplied to the tap water, the tap water cools the heat transfer tubes 11 and the aluminum fins 10. The hot air is cooled and released into the atmosphere by coming into contact with the cooled heat transfer tubes 11 and the aluminum fins 10, so that the heat load on the atmosphere is reduced. On the contrary, the tap water inside the heat transfer tube 11 of the heat exchanger coil 8 that is provided in the shape of a square in front of the outlet 2 is warmed by hot air. The warm tap water passes through the pipe 17 and is supplied to the bathtub 19 from the water supply outlet 18. By supplying the hot tap water to the bathtub 19, it is possible to reduce the utility cost of reheating the bathtub 19 and the heat load released to the atmosphere.
When the outdoor unit is not used and the room temperature of the heat exchanger coil chamber 4 is higher than the tap water temperature, the fan motor 6 is operated to rotate the fan 7 at a low speed, and at the same time, tap water is supplied to the heat transfer pipe 11 of the heat exchange coil 8. By supplying water from the tap 15 to the tap water inlet 12, the tap water inside the heat transfer pipe 11 is warmed by the outside air, and the tap water temperature rises. By supplying the tap water whose water temperature has risen from the water supply outlet 18 to the bathtub 19, it is possible to reduce the utility cost of reheating the bathtub 19 and the heat load on the atmosphere.
