Embodiment Construction

[0042] 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.

[0043] 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.

[0044] 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 pi...

Abstract

Provided is a geothermal air conditioning system. The system includes a plurality of indoor units, at least one outdoor unit, a ground heat exchanger, and an auxiliary heat source. The plurality of 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, and a plurality of compressors for compressing coolant. 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 auxiliary heat source is installed on one side of the outdoor unit to assist heat exchange of the outdoor heat exchanger.

Description

technical field [0001] The present invention relates to a geothermal air-conditioning system, in particular to an air-conditioning system comprising a plurality of geothermal heat exchangers and a plurality of compressors, the geothermal heat exchangers have a plurality of circulating pumps which can be individually and selectively Operated on the ground to perform heat exchange using ground heat, the compressor is provided at the outdoor unit and selectively used according to load. 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 ...
