Abstract: A refrigerant system is provided that includes a compressor, a motor for driving the compressor, a refrigerant system component, and a controller. The refrigerant system component can operate in a pulse width modulated mode having a loaded phase and an unloaded phase. The compressor motor is loaded in the loaded phase but unloaded in the unloaded phase. The controller applies a first voltage to the compressor motor in the loaded phase and a second voltage to the compressor motor in the unloaded phase. Here, the second voltage is less than the first voltage.

Abstract: A refrigerant system is provided with a variable speed drive for at least one of its fluid-moving devices, wherein the variable speed drive is provided by an automated mechanical drive. In the disclosed embodiment, one of the pulleys for driving the fluid-moving device has a variable diameter to vary the speed at which the fluid-moving device is driven. The pulley may include two plates that are biased in one direction by a spring or permanent magnet force, and in an opposed direction by a hydraulic or electro-magnetic force. A control adjusts the amount of hydraulic or electro-magnetic force delivered to the plates to achieve a desired speed for the fluid-moving device.

Abstract: After a chiller unit is started, an opening command of 10 pulses is output to an electronic expansion valve, and after a predetermined period of time (at the time of starting with unload) elapses, an opening command of 100 to 150 pulses is output to open the electronic expansion valve up to a predetermined opening degree. Thereafter, a discharge side refrigerant super-heat TdSH is monitored and a closing command of 1 pulse/sec is output to the electronic expansion valve to drive the same in a closing direction in a short time until TdSH becomes 20 K. After TdSH has reached 20 K, a closing command of 1 pulse/3 sec is output to the electronic expansion valve, until TdSH becomes 25 K, to drive the electronic expansion valve 3 at a smaller speed in the closing direction than that speed in the closing direction until TdSH becomes 20 K. After TdSH reaches 25 K, it is judged that an operation has shifted to a stable operation, and the opening degree of the electronic expansion valve is controlled while a suction side refrigerant super-heat TsSH is monitored.

Abstract: A multi-rotor type compressor including plural compression elements each of which includes a rotor eccentrically rotating in a cylinder and a vane which is in sliding contact with the outer peripheral surface of the rotor and partitions the inside space of the cylinder into a suck-in space in which a suck-in operation is performed and a compression space in which a compressing operation is performed, and a power save mechanism including an intercommunication path through which the compression space of a compression element is allowed to intercommunicate with the suck-in space of another compression element at a predetermined phase, an interception valve for intercepting flow of fluid in the intercommunication path, and a check valve which is provided in the intercommunication path and allows the fluid to flow therethrough in only one direction. The compression may be equipped in an air conditioner. In addition to the power save mechanism may be provided a compression stop mechanism for stopping a prescribed compression operation to reduce a part of the entire compression work of the compressor.

Abstract: Rotary compressors such as screw compressors and scroll compressors are capable of reverse operation at shutdown as the system pressure seeks to equalize through the running gear. The present invention provides a valved bypass which is opened responsive to the initiation of stopping the compressor. The valve bypass may be located internally or externally with respect to the compressor.

Abstract: A space conditioning closed loop refrigeration system, particularly a vehicle air conditioning system utilizing a positive displacement compressor having a slide valve for varying the capacity and shiftable between full load and full unload positions and vice versa and driven therebetween by a linear fluid motor having a movable member coupled to the slide valve and forming a first chamber which is normally dumped via a slide valve modulator to compressor suction pressure and a second chamber open to compressor discharge pressure. A restricted passage between chambers tends to cause the first chamber to reach compressor discharge pressure absent that chamber dumping to suction. The slide valve modulator selectively activates the venting of the first chamber to compressor suction pressure in response to fall of suction pressure below a predetermined value to prevent a serious reduction in evaporator temperature caused by either a reduction in load on the evaporator, an increase in speed of the compressor, or both. A temperature unloader in the form of a normally closed valve is connected within a bypass passage by passing the slide valve modulator to insure dumping of the first chamber to suction in response to a predetermined drop in temperature of the space to be conditioned, irrespective of the level of compressor suction pressure.

Abstract: A multi-cylinder reciprocating compressor is automatically controlled in terms of two speed operation and selective utilization of the cylinders under single stage action to meet heating and cooling loads by way of a two step indoor thermostat and an outdoor thermostat. The compressor may supply energy to storage during heating and cooling or receive energy therefrom with the storage coil selectively loop connected to the outside or indoor coils. Subcooling return is directed to a specific cylinder and overrides refrigerant return vapor to that cylinder from other coils functioning as evaporators. Solenoid operated valves effect unloading of the compressor during start up and automatically effect removal or inclusion of selected cylinders to the single stage compressor operation. Automatic load responsive control of compressor drive motor speed is effected.
