Water source heat pump applications. As the most energy efficient HVAC systems on the market, water source heat pumps (VSHP) are uniquely simple in design.

The heat is transferred through an interconnected water circuit and discharged through a cooling tower or put into operation in other areas. Each unit is an independent, packaged system, eliminating the possibility of complete system failure. If one unit falls, it will not affect other units.

Conveniently located above the ceiling or in a closet, the units can be easily accessed. VSHPs are ideal for a wide range of building types, including office buildings, apartment buildings, hotels, apartment buildings, schools and more.


VSHPs are easy to service as a residential climate and have a very long service life. This is because VSHPs do not 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 uses excess heat for space conditioning or alternative purposes and meets the needs of multiple occupants simply and efficiently, water source heat pump systems are an excellent choice.

A closed water heat pump system takes advantage of the heating and cooling requirements of each space throughout the building by recovering otherwise wasted energy in some spaces and making better use of it elsewhere in the system.

The system consists of highly efficient packed units of reverse cycle heat pumps interconnected by a water loop. Each unit meets the air comfort requirements of the specific zone in which it is installed.

In cold weather, the heat pump removes heat from the water circuit via a specially designed coaxial heat exchanger coolant-water unit and transfers it to the air. The horizontal configuration of duct units is ideal for concealed, ceiling applications. The devices are delivered with factory-installed hanger holders for use with a threaded rod and insulating rings. This model is also available in various return air configurations to enable optimal space-saving application. The device has several removable plates that provide ease of servicing.

The space above the ceiling is usually used as a return air plenum with a return air grille mounted on the ceiling. Using an exhaust channel with at least one change of direction is important to achieve the lowest sound level. Free exhaust is not recommended when low sound levels are important. The use of acoustic tiles on the ceiling is also effective for attenuating the sound. For additional sound processing, a return air plenum can be attached to the return air inlet.
