Where adequate ductwork exists, a chilled water or DX coil can be used in a blower cabinet or other enclosure to provide forced air cooling. For other residential applications, the use of circulating chilled water for hydronic cooling is advantageous. Residential chillers are based on off the shelf condensing units and appropriately sized chiller packages. Only one appropriately sized chiller unit is needed to circulate water even for a very large house. Circulating chilled water can be used with the wall or ceiling mounted valance system for quiet, comfortable hydronic cooling.
Temperature is controlled with sensors and quiet zone valves at each unit.
These units are self-cleansing. Condensate is collected in the unit and drained to the outside or the sewer system. Valance units can be furnished with dual coils as part of a four pipe system, or single coils which can be used for heating in the winter and cooling in the summer. Make up air should provide for at least two air changes per hour. Installation Installation of hydronic piping and control wiring in conjunction with IMS heating and cooling has been simplified by the introduction of a UL listed decorative surface mount support and cover system.
