Embodiment Construction

[0019] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0020] like figure 1 As shown, the heating and cooling system according to the present invention includes: a compressor 1 for compressing the refrigerant into a high-temperature and high-pressure state; The cooling mode selectively converts the refrigerant flow; the indoor heat exchanger 4 installed indoors is used to exchange heat between the refrigerant and the indoor air; the outdoor heat exchanger 3 installed outdoors is used to exchange the refrigerant with the outdoor air air for heat exchange; and expansion valve 5 to decompress and expand the refrigerant. carbon dioxide (CO 2 ) is used as the refrigerant in the heating and cooling system of the present invention.

[0021] Thus, the heating and cooling system of the present invention operates in a heating or cooling mode according to the operation of the four-way valve 2 using the refri...

Abstract

A heating and cooling system for preventing the deterioration of heating efficiency generated due to a subsidiary heat exchanger used to increase cooling efficiency. The heating and cooling system includes a compressor for compressing a refrigerant, an indoor heat exchanger for heat-exchanging the refrigerant with indoor air, an outdoor heat exchanger for heat-exchanging the refrigerant with an outdoor air, a four-way valve disposed at an outlet of the compressor for selectively discharging the refrigerant to one of the indoor and outdoor heat exchangers according to heating and cooling modes, an expansion valve for decompressing and expanding the refrigerant, an inlet refrigerant pipe for guiding the refrigerant drawn into the compressor, a subsidiary heat exchanger disposed in the inlet refrigerant pipe for heat-exchanging the refrigerant passing through the inlet refrigerant pipe and the refrigerant passing through a connection refrigerant pipe in the cooling mode so as to control the temperature of the refrigerant drawn into the compressor, and a bypass refrigerant pipe for allowing the refrigerant drawn into the compressor to bypass the subsidiary heat exchanger and then to be directed into the compressor.

Description

technical field [0001] The present invention relates to heating and cooling systems, and more particularly to heating and cooling systems that prevent loss of heating efficiency. Background technique [0002] Generally, the heating and cooling system includes a compressor for compressing the refrigerant into a high-temperature and high-pressure state, an indoor heat exchanger placed indoors, an outdoor heat exchanger placed outdoors, an expansion valve for decompressing and expanding the refrigerant, and Four-way valve located at compressor outlet to direct refrigerant to indoor or outdoor heat exchanger for switching between heating and cooling modes. In this heating and cooling system, refrigerant in a state of high temperature and high pressure is guided to an indoor or outdoor heat exchanger, thereby obtaining cooling or heating of the indoor space. [0003] The above heating and cooling system also includes an auxiliary heat exchanger, which is used to exchange heat be...
