Abstract: Just before shutdown, or at least prior to a significant pressure equalization in a refrigeration system, an accumulator containing oil is isolated from the rest of the refrigeration system in such a way that oil is at a pressure that is higher than the pressure of the rest of the system. The oil in the accumulator is maintained in a state of higher pressure while the refrigeration system is shutdown with the aid of a spring-loaded piston. Preliminary to start up of the refrigeration system, the pressurized oil is placed in fluid communication with structure requiring lubrication which is thereby lubricated.

Abstract: An improved geometry for scroll wrap inner portion includes a groove which facilitates opening of the compression chambers to the discharge ports early in the cycle of the orbiting scroll. Stated one way, a forward end of the scroll wrap tip is thinner than a portion spaced from the forward end. A first curve defines the forwardmost end of said tip and extends to a forward ledge. A second circular curve is spaced from the forward ledge and extends to a rear ledge. An intermediate curve connects the forward and rear ledges. The rear curve is centered on a second radius, and if the second radius were extended beyond the rear ledge, the extension would move to a position spaced from the forward ledge and towards the opposed wrap. The swing radius for the scroll compressor wrap measured begins at the position wherein the forward ledge of one wrap faces the rear ledge of an opposed wrap begins on one side of zero, then crosses zero with an increasing scroll wrap, and then moves to an opposed side of zero. The inventive scroll compressor wrap achieves more rapid and smooth opening of the compression chambers to the discharge ports.

Abstract: 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 in the compressor is used for economizer flow and for bypass.

Abstract: A scroll compressor has an economizer injection line communicating into the scroll compressor chambers. An unloader valve selectively communicates the economizer injection line back to suction. In this arrangement, the fluid ports and passages necessary to achieve the economizer injection are also utilized to achieve suction bypass unloading, and thus the compressor and system design and construction are simplified.

Abstract: A refrigerant system is provided with a suction pulse width modulation valve, and a pulse width modulation control for controlling this valve. System pressures, such as the pressure on the evaporator and the condenser are monitored. The measured system pressures are maintained within a band of acceptable lower and upper limits. As the pulse width modulation control cycles the valve, the refrigerant pressures in the evaporator and the condenser tend to fluctuate. The control ensures those fluctuations are within the limits by controlling the duty cycle of the valve.

Abstract: To address the problem of lubricant entrainment within the refrigerant system components such as an evaporator and suction line, a control is provided to periodically, substantially and intermittently increase the refrigerant flow through these components to thereby carry the trapped lubricant back to the compressor. The increased flow of refrigerant can be accomplished by periodically throttling and then unthrottling either an expansion device or a suction modulation valve to cause instantaneous pressure buildup within a respective section of the vapor compression system and subsequent increase of the refrigerant flow through the above-referenced components such as an evaporator and suction line. Suggested time intervals of both the throttling and unthrottling states are provided, as well as the frequency of occurrence for subsequent oil return cycles.
