Abstract: A vapor compression system includes a heat exchanger configured to facilitate heat transfer between a refrigerant and a conditioning fluid. The vapor compression system also includes an expansion valve disposed along a conduit coupled to the heat exchanger. The conduit is configured to direct a flow of the refrigerant into the heat exchanger. Additionally, the vapor compression system includes a sensor configured to provide feedback indicative of a temperature of the conditioning fluid exiting the heat exchanger and a controller including a memory and processing circuitry. The processing circuitry is configured to receive a signal indicative of the temperature of the conditioning fluid exiting the heat exchanger from the sensor and adjust operation of the expansion valve based on the signal.

Abstract: 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.

Abstract: 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.

Abstract: 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.
