The present invention relates to an absorption type air-conditioning system, and more particularly, by providing a hot water supply device to an outdoor heat source supply device to perform a normal indoor air conditioning function and additionally perform a hot water supply and hot water supply function. It relates to an absorption type heating and cooling system having a hot water supply function.

In general, absorption type air-conditioning system is a system that heats and heats a room through a cooling and cooling cycle of absorption solution and water using gas such as LPG and LNG as a raw material, and is composed of an absorption type heat source supply device and an air conditioner for heating and cooling the room. It has an advantage in that it can solve the excessive power load in the summer.

This absorption air-conditioning system, upon cooling, heats the absorption solution in the generator to vaporize a part thereof, condenses the vaporized refrigerant vaporized in the generator in the condenser, evaporates the liquefied refrigerant condensed in the condenser under low pressure, and evaporates in the evaporator. It has a refrigerant circulation cycle for absorbing the gas refrigerant from the absorber, and using the cold water cooled by the evaporation heat generated in the evaporator, the indoor air-conditioning and air conditioner to perform the indoor cooling.

During heating, the absorption air-conditioning system sends a high temperature absorbing solution heated at a high temperature in the generator directly to the evaporator through the opening of a cooling / heating switching valve, thereby causing the indoor air-conditioning and air conditioner to use the hot water heated as the high temperature absorbing solution. Allow room heating.

Conventional absorption type air-conditioning system has a problem that the versatility is greatly reduced because it does not have a separate function of supplying hot water to perform the heating and cooling of the room through the selective operation of the air conditioning cycle.

In addition, the conventional absorption air-conditioning system has caused inconvenience that the administrator or user must move to the installation place of the outdoor heat source supply device for re-ignition reset when the self-equipped heating burner has become incombustible.

Therefore, the present invention, which was devised to solve the problems of the prior art, has a hot water supply function and a hot water supply function together with a cooling and heating function to automatically operate the hot water supply system according to the working pressure of the hot water at all times. It is an object of the present invention to provide an absorption type heating and cooling system.

In addition, another object of the present invention is to provide an absorption type heating and cooling system capable of supplying hot water and hot water supply during heating and cooling, and at the same time, re-ignition reset operation of the burner of the outdoor heat source supply device.
