Problems solved by technology

[0004] However, the existing heat pump system has the problem of insufficient heating capacity during heating operation during severe cold periods when the outdoor temperature is low.
[0005] In addition, the existing heat pump system uses Freon refrigerant
Although the Freon refrigerant has good efficiency, there is a problem that it will cause environmental problems such as ozone layer destruction and global warming effect when exposed to the atmosphere.

Embodiment Construction

[0043] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0044] The composite cooling and heating system of the present invention, as shown in FIG. 1 , has a heat pump system 100 and a floor heating system 200 .

[0045] The heat pump system 100 described above uses carbon dioxide (CO 2 ) as a natural refrigerant.

[0046] The heat pump system 100 includes a compressor 1 , a four-way valve 2 , an indoor heat exchanger 5 , an expansion device 6 , and an outdoor heat exchanger 7 connected by a refrigerant pipe CL. Compressor 1 is suitable for variable capacity variable energy type. An accumulator 8 is provided on the suction side of the compressor 1, and an indoor fan motor 9 and an outdoor fan motor 10 are respectively provided on the indoor heat exchanger 5 and the outdoor heat exchanger 7 for blowing air for heat exchange.

[0047] In addition, the heat pump system 100 includes first and s...

Abstract

To provide a composite air-conditioning system that heats indoor air using a heat pump system for indoor space and heats the indoor floor using a floor heating system. The heat pump system comprises a compressor that uses carbon dioxide as a natural refrigerant and is connected by a refrigerant pipe, a four-way valve, an indoor heat exchanger, an expansion device, an outdoor heat exchanger, and a plurality of heat exchangers for supplying hot water. The floor heating system comprises a heating water supply pipe for circulating heating water, and a heating water regulating valve for regulating the flow of the heating water.

Description

technical field [0001] The invention relates to a composite cooling and heating system with a heat pump system using natural refrigerant for cooling and heating indoor air and a floor heating system using heating water for indoor floor heating. Background technique [0002] A heat pump system is an air conditioner that switches the flow of high-temperature and high-pressure refrigerant discharged from a compressor to cool or heat an indoor space. [0003] In this heat pump system, the indoor heat exchanger functions as an evaporator during cooling operation and as a condenser during heating operation. [0004] However, the existing heat pump system has a problem of insufficient heating capacity during the heating operation during severe cold periods when the outdoor temperature is low. [0005] In addition, the existing heat pump system uses Freon refrigerant. This CFC refrigerant has good efficiency, but there is a problem that it causes environmental problems such as ozo...
