Water Source Heat Pumps (WSHP)Water Source Heat Pumps (WSHP) move heat and do it more efficiently than any other heating and cooling technology. Their simplicity is truly amazing. They are as simple to service as a residential air conditioning unit, and they last an amazingly long time. ASHRAE estimates a more than twenty year life expectancy. That's because they don't have to work as hard as other systems to move heat from one place to another. For the design of an ideal heating/cooling system that offers individual zone control, recovers and utilizes excess heat for space conditioning or alternative uses, and serves multi-tenant needs simply and efficiently, water source heat pump systems are the right choice.
The closed-loop water source heat pump system is simple by design, yet it is among the most efficient HVAC systems available. These systems take advantage of the heating and cooling requirements of each space in the entire building by recovering otherwise wasted energy in some spaces and better utilizing it elsewhere in the system.
The system is comprised of highly efficient packaged reverse cycle heat pump units interconnected by way of a water loop. Each unit satisfies the air comfort requirements of the particular zone in which it is installed. In cold weather, the heat pump removes heat from the water loop via the unit's specially designed refrigerant-to-water coaxial heat exchanger and transfers it to the air.
