Product introduction
• Water Cooled VRF is a water-air heat pump air condition equipment which can deliver cooling
and heating by taking water as its heat source. Water acts as the heat-extraction source when
heating, while heat-absorption source when cooling. Thus there is no risk of frost formation on
condenser’s surface.
• Water Cooled VRF takes a water circulating loop as its heat and heat-extraction source. When
the water’s temperature in the loop is higher than the rated value because of the heat release
of the Water Cooled VRF (Cooling), the water will exchange the heat into the air through the
cooling tower. When the temperature is lower than the rated value, water heating is usually
utilized by the heating equipment or the waste heat.
• In a case of there are more than one Water Cooled VRF being installed, the whole system can
have some units running in cooling and other units running in heating, to realize the energy
saving of water side heat recovery.

Main Components
Energy-saving
The Water Cooled VRF delivers higher efficiency compared with the air-air heat pump series
because of its low condensing temperature. Individual measure of electricity consumption
on this VRF equipment is available. For example, when the building is occupied by different
tenants, the electricity charge and maintenance cost can be counted separately. Cooling and
heating simultaneously in combination system can achieve inner balance of the energy, save the
operating time of the cooling tower and heating equipment, and achieve the purpose of energy
saving.
Flexible Application
As the efficiency of the water system will not be affected by ambient temperature, users can
choose cooling or heating mode flexibly in different seasons or based on practical requirements.
This Water Cooled VRF uses "Mode Consistence" control method without refrigeration side heat
recovery function, which means all the indoor units under same outdoor system can only run
either cooling or heating at one time.
The Water Cooled VRF is composed of two parts, parallel connected Water Cooled sets and
dual circulating pipes.
The main equipment and accessories include the following: cooling equipment; heating
equipment (heat exchanger unit or boiler); water treatment equipment; expansion tank; water
circulating pump; water flow switch.
