Dual Condenser Chiller

Dual Condenser Chiller

Centrifugal Chiller - Fundamentals . Dual compressor chillers have two compressors operating in parallel between a common evaporator and condenser. For example, a 1000 ton dual will have two nominal 500 ton compressors mounted. As the chiller unloads from 100% load, one compressor shuts off at approximately 600 tons (60% of full load).

Using Heat Recovery to Improve Chiller Efficiency

Using Heat Recovery to Improve Chiller Efficiency

Dec 06, 2018 In air-cooled chillers, the heat exchanger is called a desuperheater, which rejects building load heat to the atmosphere through condenser fans during normal operation. In heat recovery mode, hot refrigerant gas leaves the compressor and enters the heat exchanger where the energy in the refrigerant gas transfers to the incoming hot water loop.

Single Stage Vs Two Stage Air Conditioner (AC Comparison)

Jul 08, 2021 When comparing single two-stage air conditioners, we have to consider their differing compressor speeds. Single-stage units have a single compressor speed, so they function at either 100% or not at all. In contrast, two-stage compressor systems have two compressor speeds, with one generally set to 60-70 percent of maximum efficiency.
