The system includes a variable speed motor operatively connected to drive the pump. A value indicative of flow rate of water is determined and the motor is controlled to adjust the flow rate indicative value toward a constant. A value indicative of flow pressure is determined and the motor is controlled to adjust the flow pressure indicative value toward a constant. A selection is made between flow rate control and flow pressure control. In another aspect, the pump is controlled to perform a first operation, and is operated to perform a second water operation. Control of operation of the pump to perform the first water operation is altered in response to operation of the pump to perform the second operation.

A bimetal member, which deforms in correspondence with the temperature in the crank chamber, is arranged in the valve chamber. A valve body, which is supported by the bimetal member, is arranged in the valve chamber. The peripheral wall has a first oil discharge passage and allows communication between the crank chamber and the valve chamber, and a second oil discharge passage through which the valve chamber and a suction chamber communicate with each other. When the temperature in the crank chamber exceeds a predetermined value and deforms the bimetal member to move the valve body, communication between the first and second oil discharge passage is permitted through the valve chamber.

The pumps and pressure controllers described herein aim to pump fluid in two directions, such as from a first port to a second port and vice versa. The pressure controllers aim to control pressure in a system or device, such as a test device, accurately and precisely at a variety of different pressure levels. Generally described, the pumps and pressure controllers described herein may include two or more control valves, which may be actuatable in such a manner so that the pump or pressure controller can switch between operating as a vacuum pump and operating as a compressor. In some embodiments, the pressure controllers may be able to adjust a pressure in the device by small increments thereby providing increased control of the pressure in the device over the prior art. Furthermore, the pressure controllers may be able to control the pressure of a system having low pressure levels.

A refrigerant discharge capacity of a high-pressure side compression mechanism and a refrigerant discharge capacity of a low-pressure side compression mechanism can be independently controlled, in a two-stage pressurizing refrigeration cycle device. The refrigerant discharge capacity of the low-pressure side compression mechanism is determined based on an outside air temperature, an air temperature at the evaporator, and a preset temperature. Furthermore, the refrigerant discharge capacity of the high-pressure side compression mechanism is determined based on the determined refrigerant discharge capacity of the low-pressure side compression mechanism such that an effective capacity ratio is not less than 1 nor more than 3. Therefore, in the two-stage pressurizing refrigeration cycle device, COP can be improved with a simple structure and control. 18-. (canceled)9.
