摘要： A method for controlling a vapour compression system (1) is disclosed, the vapour compression system (1) comprising at least one expansion device (8) and at least one evaporator (9). For each expansion device (8), an opening degree of the expansion device (8) is obtained, and a representative opening degree, ODrep, is identified based on the obtained opening degree(s) of the expansion device(s) (8). The representative opening degree could be a maximum opening degree, ODmax, being the largest among the obtained opening degrees. The representative opening degree, ODrep, is compared to a predefined target opening degree, ODtarget, and a minimum setpoint value, SPrec, for a pressure prevailing inside a receiver (7), is calculated or adjusted, based on the comparison. The vapour compression system (1) is controlled to obtain a pressure inside the receiver (7) which is equal to or higher than the calculated or adjusted minimum setpoint value, SPrec.

摘要： A cooling system controller (60) controls the capacity of a variable capacity compressor (44/244a-d) based upon the temperature of a housing being cooled, the suction pressure of the compressor or both of these criteria. The cooling system controller is capable of controlling either single-evaporator (54/254) or multiple-evaporator (54a,54,54c) refrigeration systems. The multiple-evaporator systems can have evaporators of similar temperatures or of mixed temperatures. The controller (60) also allows the use of one or more condenser fans (202,204) that are operated in a lead/lag fashion to control the cooling capability of the system.

摘要： An ejector includes a first nozzle, a second nozzle, an atomization mechanism, and a mixer. A working fluid in a liquid phase is supplied to the first nozzle as a drive flow. A working fluid in a gas phase is sucked into the second nozzle. The atomization mechanism is disposed at an end of the first nozzle and atomizes the working fluid in a liquid phase while maintaining the liquid phase. The mixer generates a fluid mixture by mixing the atomized working fluid generated by the atomization mechanism and the working fluid in a gas phase sucked into the second nozzle.

摘要： A refrigeration system can use a flash tank to separate vapor refrigerant from liquid refrigerant. The refrigeration system can include a liquid-refrigerant injection system that can inject liquid refrigerant into an intermediate-pressure location of the compressor. The injected liquid refrigerant can absorb the heat of compression during the compression process. The refrigeration system can include an economizer system that injects a refrigerant vapor into an intermediate-pressure location of the compressor in conjunction with the injection of the cooling liquid. The refrigeration system can incorporate a cooling-liquid injection system that can inject a cooling liquid into an intermediate-pressure location of the compressor.

摘要： The present invention relates to an apparatus and to a method for carrying out a cold steam process. The apparatus has a motor-operated primary compressor (C1) which is designed to draw in a mass flow of a fluid, serving as refrigerant, at evaporator pressure and to compress this mass flow to high pressure, and a high-pressure heat exchanger (H) which is designed to cool the mass flow of the fluid at high pressure, to increase the density and to reduce a temperature of the fluid. Also provided is an expander (E) which is designed to expand to evaporator pressure, so as to perform work, the mass flow of the fluid coming from the high-pressure heat exchanger (H), and an evaporator (V) which is designed to take up heat such that the density of the fluid decreases as it passes through the evaporator and the temperature of the mass flow coming from the expander (E) at evaporator pressure, and of the fluid guided through the evaporator (V), increase. Finally, there is a sub-cooler (U), which is connected downstream of the high-pressure heat exchanger (H) and upstream of the expander (E), wherein downstream of the sub-cooler (U) and upstream of the expander (E) part of the fluid can be diverted from the mass flow and can be expanded by means of a high-pressure control valve (TH) to an intermediate pressure, such that the fluid then, at intermediate pressure, absorbs heat in counter-flow in the sub-cooler (U), and thus additionally sub-cools the mass flow which is at high pressure, and a high-pressure compressor (C2) which is mechanically directly connected to the expander (E) and is designed to compress, to high-pressure, only that part of the fluid that is diverted upstream of the expander (E) in the sub-cooler (U) and guided in counter-flow, and to mix this fluid, upstream of the high-pressure heat exchanger (H) with the mass flow coming from the motor-operated primary compressor (C1).

摘要： The purpose of the present invention is to reduce the temperature of a refrigerant sucked in by a high-stage compressor and prevent the high-stage compressor from sucking in a liquid medium. This refrigeration cycle device has a compression unit having a low-stage compressor (7) and a high-stage compressor (8), a condenser (11), a first expansion valve (12), and an evaporator (17). The refrigeration cycle device is equipped with: a liquid bypass circuit (32) which branches off from a pipe connecting the condenser (11) and the first expansion valve (12), and joins into a pipe connecting the low-stage compressor (7) and the high-stage compressor (8); a third expansion valve (33) which is provided to the liquid bypass circuit (32) and adjusts the amount of the refrigerant flowing through the liquid bypass circuit (32); and a controller (40) which controls the third expansion valve (33) and increases the amount of the refrigerant flowing through the liquid bypass circuit (32) when the discharge temperature of the high-stage compressor (8) is higher than a predetermined value, and which controls the third expansion valve (33) and adjusts the amount of the refrigerant flowing through the liquid bypass circuit (32) on the basis of the suction superheat degree of the high-stage compressor (8).
