摘要： In a refrigeration cycle electric signals for a capacity control valve 5 of a variable displacement compressor 1 and an electronic expansion valve 3 are directly measured. The differential pressure across the refrigeration cycle and the refrigerant flow rate are estimated based on these electric signals, to estimate the energy condition of the refrigeration cycle. Considering an engine rotational speed, the driving torque demand of the compressor is estimated, to carry out energy control for e.g. a maximum refrigerating capacity operation, maximum efficiency operation, required minimum refrigerating capacity operation, to save fuel consumption and to carry out energy control for reducing the burden on the engine e.g. during engine idling and acceleration.

摘要： The object of the present invention is to provide a four-way switching valve which is compact and inexpensive.
A compact and inexpensive four-way switching valve contains a three-way switching valve with a valve element 3 for connecting a port B to a port A or via a sleeve 2 to a port D and a three-way switching valve with a valve element 4 for connecting a port C to the port A, or to the port D. The valves and a piston 18 for actuating these valves are coaxially arranged within a cylindrical body 1. A three-way solenoid valve 19 introduces high pressure into a pressure chamber on the upper side of the piston 18 to actuate the valve elements 3, 4 downward. Upward actuation is effected with a driving force produced by reducing the pressure in the pressure chamber and by using guides 7, 8 which have a larger pressure-receiving area than a guide 6. The valve elements 3, 4 are seated by springs 9, 10 at different times.

摘要： The displacement control valve 11, 11a for controlling a short time period of compressor displacement comprises a differential pressure sensing section and a separate valve section. Differential pressure is sensed by a small-diameter piston rod 23 such that a small-sized solenoid section suffices to control the differential pressure. A valve element 26 of larger diameter than the piston rod 23, when opened controls an increased flow rate of refrigerant, and is integral to a shaft 32. The pressure Pc from a pressure-regulating chamber is received at axial opposite ends of a reduced-diameter portion of the shaft 32. The suction pressure Ps from a suction chamber is received at axial opposite ends of the valve element 26 and the shaft 32, to balance influences of the pressures Pc, Ps such that the travel of the valve element 26 is controlled only by the differential pressure between Pd and Pc as sensed by the piston rod 23.

摘要： In a refrigerating cycle with a by-pass line 5 detouring the condenser 2 in an auxiliary heating mode the amount of circulated refrigerant is controlled in accordance with load, etc. so that the heating can be suited to such conditions. A regulator 20 for controlling the outlet pressure of the evaporator to a fixed level allows to use an evaporator 4 having ordinary pressure resistance. An accumulator 6 for temporarily storing low-pressure refrigerant liquid is provided between the outlet of evaporator 4 and a compressor 1. In an auxiliary heating mode the amount of the circulated refrigerant passing the by-pass line 5 is controlled by the accumulator 6. Simultaneously the regulator is controlling the outlet pressure of the evaporator to an essentially fixed level.

摘要： In a capacity control apparatus of a variable capacity compressor 10 a chamber 30 between a valve seat 26 and diaphragm 24 communicates with a pressure control chamber 12 of the compressor 10. Said valve seat 26 communicates outside said chamber 30 with an inhalation chamber 3 of said compressor. A valve element 25 which is pressure balanced in relation to the pressure Pc in pressure control chamber 12 is axially moveable within said chamber 30. The pressure effective areas of said valve seat 26 and of a diaphragm 24 co-acting with said valve element 25 are formed with equal sizes. Due to the relatively small diaphragm size a small sized and cheap solenoid can be used for the actuation of valve element 25. The cross-section area of valve seat 26 is relatively big and prevents a delayed control response behaviour of the capacity control apparatus.
