Problems solved by technology

That is, although there are advantages such as improved thermal efficiency, the air-conditioning system using geothermal heat still has the problem that when the coolant that has flowed through the outdoor heat exchanger after heat exchange in the indoor space is not sufficiently cooled during the cooling / heating cycle Cooling / heating cycles are less stable and less reliable when extracting heat to / from the ground

Embodiment Construction

[0037] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. The present invention provides a geothermal air conditioning system using outdoor units also known as ground source heat pumps (GSHPs). The geothermal air conditioning system is a system using geothermal heat as a heat source for an outdoor heat exchanger that exchanges heat using water having a predetermined temperature (exchange water) generated by geothermal heat.

[0038] FIG. 1 is a view showing a geothermal air conditioning system installed according to a first embodiment of the present invention, and FIG. 2 is a block diagram showing the geothermal air conditioning system according to the present invention.

[0039]1 and 2, the geothermal air-conditioning system includes one or more indoor units 200 for conditioning indoor air; one or more outdoor units 100 communicated with the indoor units 100 via a plurality of pip...

Abstract

Provided is an air conditioning system using ground heat. The system includes one or more indoor units, at least one outdoor unit, a ground heat exchanger, and a plurality of auxiliary heat sources. The one or more indoor units condition indoor air. The at least one outdoor unit communicates with the indoor units via a plurality of pipes, and includes an outdoor heat exchanger where heat exchange occurs. The ground heat exchanger is connected with the outdoor heat exchanger of the outdoor unit, and laid under the ground to allow heat to be exchanged between ground heat and a circulating medium circulating through the ground heat exchanger. The plurality of auxiliary heat sources are installed on one side of the outdoor unit to assist heat exchange of the outdoor heat exchanger. Two or more auxiliary heat sources are simultaneously used, or one of them is selectively used.

Description

technical field [0001] The present invention relates to an air-conditioning system using geothermal heat, in particular to an air-conditioning system using geothermal heat for heat exchange. The air-conditioning system includes an auxiliary heat source that can be selectively used to assist heat exchange. Background technique [0002] Generally, an air conditioning system called an air conditioner includes a cooling / heating system for cooling an indoor space by repeatedly sucking in warm indoor air, exchanging heat with a low-temperature coolant, and discharging it to the indoor space, or for cooling the indoor space by inverting Operate to heat indoor spaces. The air conditioning system provides a series of cycles of compressor-condenser-expansion valve-evaporator. [0003] Also, recently, air conditioning systems provide air conditioning functions that suck in and filter polluted air in indoor spaces, purify polluted air into clean air, and supply clean air back to indoor...
