Abstract

PURPOSE:To bring a coolant to produce a high-pressure high-temperature liquefied coolant and to accumulate exhaust heat, radiated at a time when the coolant is liquefied, in service water to use it in feed not water, which results in ability to use energy effectively, by a method wherein service water, stored in a closed water tank incorporating a condenser which liquefies a high-pressure high-temperature gas coolant, is heat-exchanged with a high-pressure high-temperature gas coolant. CONSTITUTION:A coolant, brought into high-pressure high-temperature gas by a compressor 1, enters a heat exchanger (condenser) 11 in a closed water tank 9. The closed water tank 9 has an inlet valve 12 for service water at the inside of a lower part thereof and an outlet valve 13 at an upper part thereof, and incorporates a finshaped heat exchanger 11 at the inside thereof so that a coolant and service water are easy to heat-exchanger with each other. A water level in the water tank is normally regulated by a water level regulating switch 14, a coolant enters from above to heat-exchange with service water to produce a liquefied coolant which enters an expansion valve 5 to form a reduced pressure low-temperature coolant. The coolant heat-exchanges with air, fed by a blower 3, at an evaporator 4, and enters the compressor 1 again. Meanwhile, service water, heated to high temperature by a coolant, is fed as hot water to each room through the outlet valve 13.

Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to an air conditioner with a water cooling device.

[Prior art]

Figure 1 shows a conventional air conditioner.

Inside the box, there are a compressor 1 and a condenser at the bottom, an evaporator 4 at the center, and a blower 3 at the top.The gas refrigerant heated to high pressure and temperature by the compressor 1 is liquefied by the condenser 2 and then converted to high pressure and high temperature. It becomes a liquid refrigerant. At this time, thermal energy for liquefying the refrigerant is applied to the cooling \, and the cooling water Vi is discharged to the outside while the temperature remains elevated.

The high-pressure, high-temperature liquefied refrigerant is then expanded by the expansion valve 5 to become a low-pressure, low-temperature liquefied refrigerant. This liquefied refrigerant exchanges heat with the indoor air sent by the blower 3 by the evaporator 4, and the indoor air 9! The air is cooled and blown into the room. The refrigerant becomes a low-pressure gas refrigerant and is sucked into the compressor 1 again.

In the air conditioner having the above structure, the thermal energy that is exhausted to the cooling water when the state of the refrigerant changes to high-pressure, high-temperature liquefied refrigerant is not effectively utilized.

[Purpose of the invention]

The present invention has been made in view of the above, and an object of the present invention is to effectively utilize thermal energy that is exhausted to cooling water when a refrigerant changes state to a high-pressure, high-temperature liquefied refrigerant.

[a% of the invention] The structure of the present invention is to store tap water in a sealed water tank as a condenser for liquefying a high-pressure, high-temperature gas refrigerant, and to exchange heat between the tap water in the tank and the high-pressure, high-temperature gas refrigerant. The method is characterized in that the refrigerant is a high-pressure, high-temperature liquefied refrigerant, and the tap water is warmly heated to be used as water for hot water supply.

[Embodiments of the invention]

An embodiment of the present invention will be explained with reference to FIGS. 2 and 3.

The refrigerant gasified at high pressure and high temperature by the compressor 1 enters a heat exchanger (compressor) 11 in a closed water tank 9 . As shown in Figure 3, the inside of the sealed water tank has an inlet valve 12 for tap water at the bottom and an outlet valve 13 at the top, and a fin-shaped heat exchanger 11 inside to facilitate heat exchange between the refrigerant and tap water. Built-in. The water level of the water tank is constantly adjusted by the water level adjustment switch 14. The refrigerant enters from the upper part, exchanges heat with the tap water, becomes a liquefied refrigerant, enters the expansion valve 5, and becomes a low-filling liquid refrigerant. It exchanges heat with the air sent by the blower 3 in the evaporator 4, and then enters the compressor 1 again. On the other hand, the tap water heated to high temperature by the refrigerant is supplied to the outlet valve 1 for hot water supply.
3. O is sent to each room [Effects of the Invention] As explained above, according to the present invention, the waste heat released when liquefying the refrigerant is always stored in the tap water, and the tap water is used for hot water supply. By using this, energy can be used effectively.
