Embodiment Construction

[0032] The following description relates to systems and methods for cooling and heating a passenger compartment of a motor vehicle via a climate control system incorporating a thermal adsorption heat pump. Such as figure 1 As shown in , the climate control system may be thermally coupled to the engine exhaust duct, but may not be in communication with or mounted to the vehicle's engine. The thermal-adsorption heat pump may comprise two adsorbers, each adsorber via Figure 2A-2BThe multiple core chambers shown in are coupled with corresponding antifreeze tanks.

[0033] Each adsorber may comprise a closed refrigerant circuit in which the refrigerant travels between the cord chamber within the shell of the adsorber and the adsorbent based on the temperature of the adsorbent depending on the temperature of the adsorbent flowing through the adsorber. The temperature of the pipe's HTF. The two adsorbers can be operated asynchronously and cyclically so that one adsorber is in ads...

Abstract

A vehicle climate control system includes a thermal-adsorption heat pump driven by engine exhaust heat, the heat pump including two adsorbers asynchronously switching between adsorbing and desorbing modes, each adsorber coupled with a corresponding antifreeze tank via a plurality of refrigerant-containing wick chambers. Cold heat transfer fluid (HTF) flows through the adsorber during the adsorbing mode which causes evaporation of refrigerant from the wick chambers, thereby cooling antifreeze, whereas hot HTF flows through the adsorber during the desorbing mode which causes condensation of refrigerant at the wick chambers, thereby heating antifreeze. In this way, the thermal-adsorption heat pump may condition cabin air independent of engine coolant and without exerting a load on the engine.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application Serial No. 61 / 684,080, filed August 16, 2012, the entire contents of which are incorporated herein by reference for all purposes. technical field [0003] The present description generally relates to methods and systems for climate control of motor vehicles comprising a thermal-adsorption heat pump with two adsorbers. Background technique [0004] In some automotive climate control systems, thermal adsorption heat pumps may be used in place of compressor driven heat pumps. Thermal adsorption heat pumps use chemical adsorbents (e.g. zeolites, silica gel, activated carbon) rather than mechanical compressors, and are driven by thermal energy (e.g. exhaust heat) rather than mechanical work. [0005] One cycle of operation of a thermal adsorption heat pump consists of: (during here called "adsorption mode") adsorption of a refrigerant such as water onto a solid...
