Problems solved by technology

[0003] However, since the absorption chiller or the cooling heat source machine is used as a heat source machine, equipment such as a cooling water system is also necessary. Therefore, although one heat source machine is enough, the place and use that must be maintained have certain limitations. The outdoor unit of the above-mentioned compressor is used as the heat source machine in many cases, and it is impossible to disperse the heat source machines

Embodiment Construction

[0049] Embodiments of the present invention will be described in detail below according to the accompanying drawings.

[0050] Fig. 1 is the air conditioner of the present invention.

[0051] The air conditioner 100 includes an outdoor unit 1 such as a built-in engine 10 and a compressor 11, a cooling unit 2 that exchanges heat between a refrigerant discharged from the compressor 11 and water in a water heat exchanger to generate cold or warm water, and a cooling unit 2 that uses water from the compressor 11 to generate cold or warm water. The refrigerant discharged from the compressor 11 directly exchanges heat with the indoor air. A plurality of direct-expansion indoor units 3a, 3b are connected by liquid pipes 5a, 5b and gas pipes 5c, and the cooling unit 2 and the cooling unit will be connected to each other. 2 The fan coil unit 4a, 4b which circulates the generated cold water or warm water by the circulation pump 6 and exchanges heat with the indoor air is connected by th...

Abstract

An air conditioner provided with a heat source unit built in with a compressor, and carrying out air conditioning operation by supplying heat sources from both a refrigerant pipe and a water pipe. The air conditioner 100 is composed of an outdoor unit 1 built in with a compressor 11, direct expansion indoor units 3a and 3b provided with indoor heat exchangers 30a and 30b having a refrigerant delivered from the compressor 11 directly carry out heat exchange with indoor air via liquid pipes 5a and 5b and a gas pipe 5c, a chiller unit 2 carrying out heat exchange with the refrigerant to produce cold water or hot water, and fan coil units 4a and 4b provided with water heat exchangers 40a and 40b circulating the cold water or the hot water produced by the chiller unit 2 by operating a circulating pump 6 and carrying out heat exchange with indoor air. In a gas lacking state, the circulating pump 6 is operated, and an electric expansion valve 21 is opened to avoid the gas lacking state, and to prevent freezing of cold temperature water.

Description

technical field [0001] The present invention relates to the structure of an air conditioner, and more particularly to a replacement device for an air conditioner using an absorption refrigerator and the like and a fan coil unit. Background technique [0002] In the prior art, for example, in order to use an absorption type warm water machine or a cooling heat source machine as a heat source machine for indoor air conditioning, water piping is laid in a building, a fan coil unit is connected to the water piping, and the water piping is connected to a fan coil unit. The cold water or warm water generated in the heat source unit is circulated by the circulation pump to perform air conditioning operation; in order to use the outdoor unit with the compressor that compresses and discharges the refrigerant as the heat source unit for indoor air conditioning, lay the refrigerant in the building The indoor unit is connected to the refrigerant piping, and the refrigerant discharged fr...
