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.
Advantages
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.
Attentions
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.
Main Components
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.
