Abstract: An absorption based heater is constructed on a fluid barrier heat exchanging plate such that it requires little space in a structure. The absorption based heater has a desorber, heat exchanger, and absorber sequentially placed on the fluid barrier heat exchanging plate. The vapor exchange faces of the desorber and the absorber are covered by a vapor permeable membrane that is permeable to a refrigerant vapor but impermeable to an absorbent. A process fluid flows on the side of the fluid barrier heat exchanging plate opposite the vapor exchange face through the absorber and subsequently through the heat exchanger. The absorption based heater can include a second plate with a condenser situated parallel to the fluid barrier heat exchanging plate and opposing the desorber for condensation of the refrigerant for additional heating of the process fluid.

Abstract: Systems and methods for compressor-assisted sorption rate. A sorption system includes a sorber that absorbs and desorbs a refrigerant gas, such as ammonia, onto and from a coordinative complex compound. The system includes an evaporator, a condenser, and a compressor. The temperature and pressure of the gas within the sorber are monitored and the compressor is controlled to adjust the pressure to increase the absorption and desorption rates and increase the thermal cycle speed of the sorption system for applications such as laser systems requiring rapid, periodic cooling.

Abstract: A dehumidifier for a compressor, including: a plurality of dehumidifying members that absorb moisture; and a flow passage controlling valve module that enables a low-temperature vapor refrigerant to alternately flow into the plurality of dehumidifying members and enables the low-temperature refrigerant to flow into a compressor in a state where moisture contained in the low-temperature refrigerant is absorbed and is removed, enables a high-temperature vapor refrigerant ejected from the compressor to alternately flow into the dehumidifying members and regenerates the dehumidifying members. Thus, since a liquid-state absorbent contained in a refrigerant flowing into the compressor is removed by the dehumidifier, damage caused by liquid compression and corrosion of the compressor can be reduced. In addition, the structure of the dehumidifier is simple, and an additional external heating source is not required.
