Water Source Heat Pump (WSHP) systems are one of the most efficient, environmentally friendly ways to heat and cool buildings because of their ability to move energy from where it is not needed to where it is needed.
High-efficiency, self-contained McQuay WSHP units can be placed in virtually any location within the building and connected via a water loop. Heat is added and rejected from the loop using a boiler and a cooling tower, or using geoexchange from natural sources such as the ground, a pond or a well. Each unit responds only to the heating or cooling load of the individual zone it serves. This provides excellent comfort levels for occupants, better control of energy use for building owners and lower seasonal operating costs.
Systems are commonly applied to office buildings, hotels, health care facilities, banks, schools, condominiums and apartments.
