City Multi Water Source

It is possible now to combine the features of VRF with a water circuit using City Multi Water source VRF system. In this format the heat is rejected to a water loop. Benefits of water source VRF systems are greater diversity, flexibility, supreme thermal comfort and increased COP level.

The Water source VRF is capable of operating in a wide range of entering water temperatures. Low limit standard entering water temperature is 50⁰F and that can be lowered further to 23⁰F with the addition of glycol in the water loop of entering water to VRF condenser.

City Multi water source VRF system can be integrated into geothermal system (Heating and cooling loop). During summer, City Multi Ground source heat pump removes heat from the building and disperses in the ground. In winter, thermal energy is extracted from the ground and used to heat the building.

Water source VRF system is comprised of single or multiple heads connected to VRF water source condenser(s) via refrigeration piping. On the hydronic side Water source VRF condenser(s) is connected to heat adder and heat rejecter or geothermal system via hydronic water piping.

City Multi Water source VRF system is applied in almost all types of thermal comfort applications including but not limited to, high, medium & low rise condominiums, commercial offices and buildings, schools, colleges, universities, religious buildings, hospitals, gymnasiums, community centers, hotels, hostels, strip malls, shopping malls in new, replacement, retrofit and upgrade scenarios.
