摘要： Refrigerant is circulated through an economized refrigeration system including a compressor, a gas cooler, a main expansion device, an economizer heat exchanger and an evaporator. After cooling, the refrigerant splits into an economizer flow path and a main flow path. Refrigerant in the economizer flow path is expanded to a low pressure and exchanges heat with the refrigerant in the main flow path in the economizer heat exchanger. The refrigerant in the main flow path is then expanded and heated in the evaporator and enters the compressor, completing the cycle. An accumulator positioned between the economizer heat exchanger and the compressor stores excess refrigerant in the system, regulating the amount of refrigerant in the system and the high pressure in the system. The amount of refrigerant in the accumulator is controlled by regulating the economizer expansion device. By adjusting the amount of refrigerant in the accumulator, the amount of refrigerant in the system, and therefore the high pressure of the system, can be regulated.

摘要： A vapor compression system includes a compressor, a gas cooler, an expansion device, and an evaporator. Refrigerant is circulated through the system. The high side pressure of the vapor compression system is selected to optimize the heating capacity. In one example, the optimal high side pressure is obtained by determining the high side pressure that correlates to the maximum current required to operate to the water pump. In another example, the actual temperature of the water entering the gas cooler, the water exiting the gas cooler, and the ambient air temperature are measured and compared to a predetermined value to determine the optimal high side pressure.

摘要： Refrigerant is circulated through a vapor compression system including a compressor, a gas cooler, an expansion device, and an evaporator. Preferably, carbon dioxide is used as the refrigerant. The expansion device is a work recovery device which extracts energy from the expansion process and is coupled with a fluid pumping device that cools the refrigerant flowing through the gas cooler. The fluid pumping device pumps fluid through the gas cooler at a flow rate related to the energy extracted from the expansion process. The system provides a self-controlling mechanism to regulate the pressure in the gas cooler. If the pressure in the gas cooler increases, more energy is extracted from the expansion process, increasing the flowrate of the fluid pumping device, and decreasing the pressure of the refrigerant in the gas cooler. If the pressure in the gas cooler decreases, less energy is extracted from the expansion process, decreasing the flowrate of the fluid pumping device, and increasing the pressure of the refrigerant in the gas cooler.

摘要： A suction line heat exchanger storage tank for use in a vapor compression system to increase the efficiency and capacity of the system. Carbon dioxide is preferably used as the refrigerant. The high pressure of the system (gas cooler pressure) is regulated by adding charge to or removing charge from the system and storing it in a storage tank. The suction line heat exchanger exchanges heat internally between the high pressure hot refrigerant fluid discharged from the gas cooler and the low pressure cool refrigerant vapor discharged from the evaporator. The high pressure is regulated by adjusting valves. A first valve allows excess charge from the system to enter the storage tank if the pressure in the gas cooler is too high. If the pressure in the gas cooler is too low, a second valve is opened to allow excess charge from the storage tank to reenter the system. By regulating the high pressure of the system, the evaporator inlet enthalpy can be controlled to achieve optimal efficiency and/or capacity.

摘要： A heat pump system has a separate outdoor coil which is mounted below the primary outdoor coil and connected in parallel with it by valves. On system start up in the heating mode, the inlet of the auxiliary coil is closed, and the outlet is opened so that compressor vacuum will boil off the more volatile, high pressure components thus filling the system. The outlet valve is then closed trapping the low pressure component in the auxiliary coil. In a second embodiment, the accumulator is utilized to assist the auxiliary coil in vacuum separation of the refrigerant blend. Variants include blocking flow through the expansion valve on start up.
