Abstract: A heat pump system and method of use are disclosed for cooling or heating utilizing a refrigerant that includes a compressor, an ejector in fluid communication with an output of the compressor, a condenser in fluid communication with an output of the ejector, a throttling valve in fluid communication with an output of the condenser. An evaporator having an input in fluid communication with an output of the throttling valve and an output in fluid communication with an input of the ejector and an input of the compressor. There is also disclosed for data centers, a combination evaporator-OHPs and the second plurality of combination evaporator-ejector OHPs for cooling a plurality of servers where the first plurality of combination evaporator-OHPs and the second plurality of combination evaporator-ejector OHPs each include an adjacent wicking structure that is adjacent to a vapor channel and a liquid channel.

Abstract: An efficient heat pump ejector vacuum dryer system and associated method of use for drying items that includes a drying vessel having a condenser and having a first evaporator where the first evaporator has an input that is connected to an output of the first expansion valve, a first expansion valve connected in fluid communication between the condenser and the first evaporator, a second expansion valve connected between the condenser and the second evaporator, a compressor having an input connected to an output of the first evaporator, an ejector that receives a vapor stream from an output of the compressor and receives a vapor stream from the output of the second evaporator generates as an output a high-temperature vapor provided to a condenser of the drying vessel to dry the items and generate an output of moisture, and a water reservoir that accumulates water from the drying vessel.
