Combined cooling and heating system tri-function chiller

H.Stars air source cooling and heating chillers,also called Tri-function chillers have five major functions: cooling, heating, hot water, cooling with hot water, and heating with hot water.
It can be used in summer for cooling, and at the same time to produce hot water, or just for cooling alone; in spring and autumn when there is no need for cooling and heating, it can be used to produce hot water; and it can be used for heating and producing hot water in winter.
The integrated microcomputer control system enables them to automatically identify and adjust operating conditions according to actual water temperature and purpose of use. In addition to fully automated intelligent control, they may also be subject to remote management program, in which remote service is made possible through feedback of system operation information.
These energy-saving, environmentally friendly, multi-functional, compact structured, space saving, and easy-to-install systems are suitable for hotels, villas, hospitals, schools and other places with demand for cooling and heating.

Combined cooling and heating system tri-function chiller


Cooling/hot water mode

When turned on, the combined cooling and heating system chiller is in the cooling/hot water mode, which produces free domestic hot water during the cooling process; when the air conditioning chilled water reaches its set value but the domestic hot water does not,the system will automatically switch to hot water mode;

when the domestic hot water reaches its set value, but the air conditioning chilled water does not, the system will automatically switch to cooling water mode; and when both air conditioning chilled water and domestic hot water reach their own set value, the compressor stops and the system enters into the standby mode .


Heating/hot water mode

Winter heating-hot water mode 1 (with priority on hot water): When turned on, the system will go into hot water mode, and when the hot water temperature reaches its set value, the system will automatically switch to heating mode; when the hot water temperature drops below the set value again, the system

will switch back into hot water mode again; and when both hot water and floor heating temperatures reach their respective set values, the compressor stops and the system enters into the standby mode. Winter heating-hot water mode 2 (with priority on heating): When turned on, the system will go into heating mode, and when the heating reaches its set value, the system will automatically switch to hot water mode; when the heating temperature drops below the set value again, the system will switch back into heating mode; and when both hot water and floor heating temperatures reach their respective set values, the compressor stops and the system enters into the standby mode.


Hot water mode

The system will run the mode of producing domestic hot water; when the hot water temperature reaches the set value, the compressor stops and the system enters into the standby mode; and when the hot water drops below the set value again, the system will automatically start to produce hot water.


Heating mode

The system will run the heating mode; when the floor heating temperature reaches the set value, the compressor stops and the system enters into the standby mode; and when the heating temperature drops below the set value again, the system will automatically start the heating process.



Cooling mode

The system will run the cooling mode; when the cooling temperature reaches the set value, the compressor stops and the system enters into the standby mode; and when the chilled water temperature rises above the set value again, the system will automatically start the cooling process. (To avoid frequent switches between modes, cooling mode can be selected in summer, when hot water is not needed)
