A subassembly for an adsorption chiller includes an adsorption component that includes a plurality of plates arranged in a stack. Refrigerant passages are defined between refrigerant sides of adjacent pairs of the plates in the stack. An adsorbent material is disposed within the refrigerant passages.

An adsorption core has (i) a heat medium tube in which a heat medium flows and (ii) an adsorption agent that adsorbs a fluid in a vapor phase outside of the heat medium tube when being cooled by the heat medium and desorbs the absorbed fluid when being heated. The heat medium tube has (i) a core member that is made of metal having a higher hardness with respect to copper and (ii) a covering layer that is made of copper and covers an outer surface of the core member. A sintered body of a copper powder and the adsorption agent is provided in a peripheral portion of the heat medium tube. The copper powder and the heat medium tube are metallically coupled with each other. Accordingly, stiffness of the heat medium tube can be higher while improving a heat transfer performance between the heat medium tube and the adsorption agent.

The present invention relates to a novel split level sorption refrigeration system. In particular, the present invention provides a split level sorption based unit as a novel method of using the traditional sorption based refrigeration unit. The present invention offers orientation free configuration with efficient cooling power delivery to the various cooling load locations which is achieved by splitting the evaporator of the sorption chiller from the sorption beds and the condenser.

A conditioning system for a conditioned interior space includes a vapor compression system, an evaporative cooling system, and a controller. The vapor compression system includes an evaporator, a condenser, a refrigerant active fluid for flowing between the evaporator and the condenser, a first fan to produce a first airflow toward the conditioned interior space, and a second fan for producing a second airflow from the condenser toward an exterior space. The evaporative cooling system includes a first tank containing a non-refrigerant active fluid, and a heat exchange device fluidically coupled to the first tank to receive the non-refrigerant active fluid. The first fan is positioned to produce the first airflow through the heat exchange device toward the conditioned interior space. The controller is programmed to control cooperative operation of the vapor compression system and the evaporative cooling system to condition the conditioned interior space.
