Abstract: A pulse width modulation control is provided for a suction valve on a suction line, delivering refrigerant into a housing shell of a compressor. When the suction valve is closed, the pressure within the housing shell can become very low. Thus, a pressure regulator valve is included within the refrigerant system to selectively deliver a limited amount of refrigerant into the housing shell when the suction valve is closed. The delivery of this limited amount of refrigerant ensures that a specified pressure is maintained within the housing shell to achieve the most efficient operation while at the same time preventing problems associated with damage to electrical terminals, motor overheating and excessive discharge temperature.

Abstract: A reciprocating piston compressor for use in a refrigerant compression circuit comprises first and second intake manifolds, first and second reciprocating piston compression units, an outlet manifold and a first pulsing valve. The intake manifolds segregate inlet flow into the compressor. The first and second reciprocating piston compression units receive flow from the first and second intake manifolds, respectively. The outlet manifold collects and distributes compressed refrigerant from the compression units. The first pulsing valve is mounted externally of the first intake manifold to regulate refrigerant flow into the first intake manifold. In another embodiment, a second valve is mounted externally of the second intake manifold to regulate flow into the second intake manifold, and the first and second valves are operated by a controller. The controller activates the first valve with variable width pulses having intervals less than an operating inertia of the refrigerant compression circuit.

Abstract: A refrigerant system is provided with an expansion device that may be a thermostatic expansion device or an electronic expansion device. A bypass line selectively allows a portion of refrigerant to bypass the expansion device and to flow through a fixed restriction expansion device such as an orifice positioned in parallel configuration with the main expansion device. A valve selectively enables or blocks refrigerant flow through this bypass line depending on the volume of refrigerant required to circulate through the refrigerant system as defined by environmental conditions and a mode of operation. The valve can be a simple shutoff valve or a three-way valve selectively allowing or blocking refrigerant flow through a particular refrigerant line or lines. In one embodiment, the expansion device is the main expansion device for the refrigerant system. In the other embodiment, the expansion device is a vapor injection expansion device for expanding refrigerant for performing an economizer function. The present invention allows the use of a smaller expansion device, which can be more precisely controlled, while still allowing the accommodation of higher refrigerant mass flow when necessary.
