摘要： Methods and systems to manage refrigerant levels in a chiller system are provided. An evaporator of the chiller system may be configured to have a spill over port allowing oil containing refrigerant to spill over through the spill over port. The spill over port may be positioned at a place that corresponds to a desired refrigerant level in the evaporator. The spill over refrigerant may be directed into a heat exchanger that is configured to substantially vaporize refrigerant of the spill over refrigerant to a slightly superheat temperature. A method of maintaining a proper refrigerant level in the evaporator may include regulating a refrigerant flow to the evaporator so that the vaporized refrigerant of the spill over refrigerant is maintained at the slightly superheat temperature.

摘要： A method for increasing efficiency of a transcritical heat pump water heater system is provided, as well as the corresponding system. The refrigerant, such as CO2, is compressed to a supercritical point and passed through a gas cooler that is wrapped at least partially around a water storage tank, wherein the refrigerant transfers heat to water stored in the tank. The hot water is discharged from the storage tank proximate to a top of the tank, and cold water is introduced into the tank proximate to a bottom of the tank. The supercritical refrigerant is directed to flow through the gas cooler from a top point to a lowermost point in a flow direction such that the refrigerant exits the gas cooler proximate to the bottom of the tank at a location of the coldest water within the storage tank.

摘要： Adsorption cooling apparatus with an intermittently heated adsorbent container (12) containing an adsorbent (19) that exothermically adsorbs a working medium during an adsorption phase and again desorbs at higher temperatures while heat is added during a subsequent desorption phase, and with a condenser (4) that leads condensed working medium through a connection line (10) into the evaporator (4) which is in turn connected with the adsorbent through a working medium vapor line (9), wherein the condenser (4) is coupled to a buffer reservoir (14) that buffers at least a part of the condensation heat of the working medium vapor and that also can again dissipate the stored heat into the surroundings even during the adsorption phase.

摘要： A condenser for a heating, ventilation, air conditioning and refrigeration system includes a condenser shell, a refrigerant inlet located at the condenser shell, and a condenser drain located at the condenser shell. A condenser tube bundle is located in the condenser shell such that a refrigerant flow entering the condenser via the refrigerant inlet passes over the condenser tube bundle before exiting the condenser at the condenser drain. Two or more condenser ballast volumes are located in the condenser shell between the tube bundle and the condenser drain. The two or more condenser ballast volumes are spaced apart to define a channel therebetween. A condenser ballast volume of the two or more condenser ballast volumes has a horizontal top surface.
