Absorption refrigeration and heat pump system with defrost
This patent describes an absorption refrigeration and/or heating system in connection with a primary source of heat, a cooling or heating load, and a heat sink or secondary source, to selectively provide heat to or remove heat from the load, including components. It comprises a multiple effect generator means having multiple desorber components to apply the primary source of heat to an absorption solution pair comprising a highly volatile refrigerant, and an absorbent and to desorb refrigerant from the pair; a condenser means connected to the multiple desorber components of the generator means; an evaporator means connected to the condenser means; an absorber means connected to the evaporator means; a pump means connected between the absorber means and the generator means to transfer solution to the generator means at higher pressure; and a heat transfer subsystem for conveying a working fluid and between the components and having multiple switchable valve means; and pump means.
