Patent Number Title Of Patent Date Issued
RE42966 Tandem compressors with discharge valve on connecting lines November 29, 2011
A refrigerant cycle is disclosed having a number of compressors operating in tandem and supplying a compressed refrigerant to a refrigerant system. Discharge lines communicate a compressed refrigerant to a central discharge line for receiving flow from all tandem compressors. A control
RE40499 Pulsed flow for capacity control September 16, 2008
Step control in capacity modulation of a refrigeration or air conditioning circuit is achieved by rapidly cycling a solenoid valve in the suction line, economizer circuit or in a bypass with the percent of "open" time for the valve regulating the rate of flow therethrough. A common port
RE39597 Variable speed drive chiller system May 1, 2007
The compressor in a refrigeration system is controlled solely by a variable speed drive which controls the motor of the compressor by virtue of the varying of the frequency of the electricity provided to the motor. To minimize the initial cost and to minimize operating costs, the var
RE39346 Scroll compressor with lubrication of seals in back pressure chamber October 17, 2006
A scroll compressor lubrication system includes a number of embodiments where lubricating oil impinges off surfaces adjacent to the orbiting scroll. The impinged oil creates a lubrication mist, which is deposited on the back surface of the orbiting scroll baseplate. The surface of the
RE37837 Reverse rotation prevention for scroll compressors September 10, 2002
In a scroll compressor, under conditions favoring reverse operation, the scroll wraps are separated so as to provide a continuous, unimpeded path through the scrolls. Spring bias, a repositioning of driving contact areas and/or force areas can be used singly or in combination to cause
RE36743 Pre-mix flame type burner June 20, 2000
A burner for burning a combustible gas comprising fuel gas and air that has been mixed before being supplied to the burner. The burner has a flame holder .[.concavely.]. .Iadd.axially and radially .Iaddend.recessed into a flame outlet. The .[.concave.]. configuration of the flame holder
RE36053 Compact Oldham coupling January 19, 1999
A pair of keys of an Oldham coupling are located on a chord spaced from a diameter and are of a parallelogram shape. The ends of the corresponding slots are located at the same radius whereby a reduced envelope results.
RE35760 Method of making a scroll compressor pump cartridge subassembly April 7, 1998
The crankcase, fixed and orbiting scrolls and Oldham coupling are assembled to make a pump cartridge assembly as a subassembly of a scroll compressor. The pump cartridge assembly is tested to determine whether or not it operates satisfactorily. Upon successful testing, the pump cartridge
RE30765 Heat pump system October 13, 1981
A reversible vapor compression system having control means associated therewith for automatically routing refrigerant through the heat exchangers in response to a system mode of operation to produce optimum system performance when the system is called upon to produce either heating o
RE30433 Heat exchanger November 11, 1980
A heat exchanger for use in a reversible refrigeration system. The exchanger is divided into a plurality of heat transfer zones containing one or more circuits. Control means are provided to route refrigerant through each zone in a series progression when the heat exchanger is servin
RE30275 Heat exchanger May 20, 1980
A heat exchanger for use in a reversible refrigeration system. The exchanger is divided into a plurality of heat transfer zones containing one or more circuits. Control means are provided to route refrigerant through each zone in a series progression when the heat exchanger is servin
RE30252 High temperature heat recovery in refrigeration April 8, 1980
A high lift energy reclaiming circuit for use in a vapor compression refrigeration system, the circuit being interposed in the system between the compressor discharge line and the condenser inlet line. Refrigerant vapors discharged from the compressor are exposed to, and condensed into,
RE30242 Heat pump system April 1, 1980
A reversible vapor compression system having control means associated therewith for automatically routing refrigerant through the heat exchangers in response to a system mode of operation to produce optimum system performance when the system is called upon to produce either heating o
