Refrigeration Compressors and Air Conditioning Compressors Specifications

Help with Refrigeration Compressors and Air Conditioning Compressors specifications:

Nominal Cooling Specifications

	Capacity:		Capacity of the compressor to remove heat from the refrigerant gas.  This is most frequently a nominal rating, that is, based on a standard set of conditions including Condensing Temperature (CT), Evaporative Temperature (ET), refrigerant, motor RPM, etc.  Typically a compressor can be run at many different values for these parameters, with corresponding changes in the cooling capacity. Typical units are kilowatts, tons of refrigeration, or BTU/hour.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Input Power:		Power required to run the compressor motor at the rating point.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Condensing Temperature:		Range of condensing temperature over which the compressor is rated.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Evaporative Temperature:		Range of evaporative temperature over which the compressor is rated.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

Compressor Construction

	Your choices are...
	Scroll		Refrigerant gas is moved as intake air is compressed between the surfaces of mating involute spirals, one of which is moving to progressively push the evacuated air out to the exhaust.
	Screw		One screw spindle compresses intake gas or multiple spindles with intermeshing screws rotate oppositely, creating axially progressing "chambers," moving the gas from suction to discharge.
	Piston		Motor-driven piston(s) mechanically reduces gas volume inside cylinder; often are rated for high pressure.
	Other		Any unlisted compressor construction.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
