Embodiment Construction

[0035] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0036] Fig. 1 shows a top view, illustrating the situation that a water-cooled air conditioner is installed in a building according to an embodiment of the present invention, and Fig. 2 illustrates the air and air in a building when the integrated water-cooled air conditioner is in operation according to an embodiment of the present invention. The condition of the water flow.

[0037] 1 and 2, a water-cooled air conditioner is installed in a closed space S of a building B. Referring to FIG. The closed space S is completely isolated from the outer wall of the building B, and communicates with the indoor space through the air inlet H formed through the ceiling to suck in indoor air.

[0038] The duct D is connected to the indoor space R, and releases the air that is heat-exchanged with the water-cooled air conditioner into ...

Abstract

A water-cooled air conditioner and a method controlling the same are provided. The water-cooled air conditioner includes a first heat exchanger where indoor air is heat-exchanged with refrigerant, a compressor for compressing the refrigerant, a plate-shaped second heat exchanger where the refrigerant compressed by the compressor is heat-exchanged with the water, and a freeze-crack preventing unit that is provided at a side of the second heat exchanger to prevent the water in the second heat exchanger from freezing.

Description

technical field [0001] The present invention relates to a water-cooled air conditioner, and more particularly, to a water-cooled air conditioner that prevents water flowing along an inner passage of a heat exchanger from freezing by using an antifreeze crack prevention unit on one side of the heat exchanger. Background technique [0002] In general, air conditioners are designed to lower indoor temperatures by (a) absorbing warm indoor air (b) exchanging heat with refrigerant for warm indoor air (c) releasing the heat-exchanged air into the room to raise the room temperature Then the reverse cycle can be used. Air conditioners provide a cooling / heating cycle in which refrigerant circulates through a compressor, condenser, expansion valve, and evaporator. [0003] Recently, with the improvement of the quality of life, according to the needs of consumers, in addition to the cooling / heating function, the air conditioner also provides other functions, such as the air purificati...
