Abstract
Official abstract text for this publication.
A refrigerant system control operates tandem compressors. If one of the monitored system conditions does not change as each of the tandem compressors or associated components is brought on line, then a determination is made that the respective component is malfunctioning. A refrigerant system can also be additionally equipped with other functions and components, such as variable speed drive, economizer circuit, unloader bypass, and reheat circuit. In case of a reheat circuit, the system can have single or multiple compressors. The control algorithm can also be updated such that that particular malfunctioning component is eliminated from the operational sequence.
First claim
Opening claim text (preview).
What is claimed is: 1. A refrigerant system comprising: a tandem compressor bank including a plurality of compressors receiving refrigerant from a suction manifold, compressing the refrigerant and delivering the refrigerant into a discharge manifold; a condenser positioned downstream of said compressor bank, an expansion device positioned downstream of said condenser, and an evaporator positioned downstream of said expansion device, refrigerant passing from said compressor bank…
