Chillers Installed by Unique Indoor Comfort 

Chillers provide both heating and cooling solutions.  Unique Indoor Comfort's designs allows homeowners and building owners to have systems without refrigerant inside the conditioned space.  The ability to connect to multiple air handlers with one chiller provides exterior design options since the mutliple air conditioners are no longer needed.

 UniChille RC

The revolutionary UniChiller RC outdoor heating and cooling unit represents the latest innovation in home comfort from Unico, Inc., manufacturer of the small-duct Unico System. This outdoor unit is perfect for residential and light commercial applications and provides both hot and cold water for central heating and/or cooling.Features

• Reverse cycle operation
• Quiet; side fan discharge system
• Sealed refrigerant system
• Stainless steel pump
• Low maintenance
• Minimal footprint

• Heats as well as cools
• Quiet operation
• No refrigerant in the conditioned space; unlimited remote location
• Allows for multiple air handlers (zones)
• Can be banked with multiple Chiller units
• Highly efficient

The Unichiller is a self-contained, outdoor, air-cooled liquid chiller or reverse-cycle liquid chiller. It uses R-22 refrigerant as a working fluid to cool or heat water, which, in addition to being safer for the environment, is more energy efficient than conventional air conditioning. It also can provide zoned cooling or heating with just a single unit, so you can use multiple air handlers to provide cooling or heating only to those areas in need of it at any given time.

Applications

Unichillers can be used in residential, light commercial and some industrial applications. The
heating mode of the Unichiller is suitable for radiant floor heating and snow melt in addition to air heating applications.

Unichillers can be undersized up to 20% if there is more than one zone and if not all the zones will be operating at the same time. A Manual N (load diversification) calculation can also be done to see if the chillers can be undersized further. Condensing units have to be sized exactly to match the airandling unit.
Unichillers are designed for partial load (less than design) conditions. Therefore, zoning is possible and easy with Unichillers. Condensing units are designed only for full load conditions making zoning very hard.

The Unichillers are pre-charged and self-contained so unless breaking into the refrigerant lines is necessary, there is no need for a refrigeration license. For a condensing unit, a refrigeration license is mandatory for both installation and service.  Remote locations up to 300 ft (91 m) away are possible with Unichillers as long as the water lines are sized in accordance with this manual. However, a condensing unit has to be close to the house,
typically less than 75 ft (23 m). Refer to individual condenser manufacturer for exact limitations.

The Unichiller is quieter than a typical outdoor condensing unit. It has two fans compared to one fan on most condensing units.

Key Features

• Unichiller is a self-contained and pre-charged unit. Therefore, there is no refrigerant handling during installation. The contractor connects only the water piping and electrical power. There is no refrigerant inside the house.

• It is easy to zone because there is no freeze-up problems caused by partial load conditions.

• The Unichiller operates based only on the water temperature sensed by the temperature controller inside the unit (unless the installer made modifications to the controls).

• Piping is simple and cost effective.

• The Unichiller is quieter than a typical condensing unit.

• It can be placed at a remote location as long as the piping is sized in accordance with desing specifications.
  

• There is no need for a large area around the unit.

• It is possible to bank multiple units for larger loads.
