The rate of water vapor sorption of an absorption cycle cooling and/or heating system using an aqueous alkali metal halide solution as the working fluid is increased by adding to the fluid an effective additive amount of at least 2 parts per million of an aliphatic, cycloaliphatic, or aromatic ketone or aldehyde capable of increasing the rate of water vapor absorption.

Heat and mass transfer additives for improved aqueous absorption fluids

An aqueous absorption fluid composition, process and apparatus wherein the absorption fluid contains at least one monofunctional ether heat and mass transfer additive which provides improved water vapor absorption and thermal transfer in thermal exchange loops used in absorption refrigeration, chilling, heat pump, energy storage and other thermal transfer applications.

Monofunctional ether heat and mass transfer additives for aqueous absorption fluids

An aqueous absorption fluid composition, process and apparatus wherein the absorption fluid comprises certain ethers providing improved water vapor absorption and thermal transfer in thermal exchange loops used in absorption refrigeration, chilling, heat pump, energy storage and other thermal transfer applications.

Ether heat and mass transfer additives for aqueous absorption fluids

The rate of water vapor sorption of an absorption cycle cooling and/or heating system using an aqueous alkali metal halide or hydroxide solution as the working fluid is increased by adding to the fluid an effective additive amount of at least 2 parts per million of a primary, secondary or tertiary aliphatic, cycloaliphatic, heterocyclic or aromatic amine to the fluid capable of increasing the rate of water vapor absorption.

Aqueous absorption fluids

A valve assembly includes a refrigerant inlet port and a refrigerant outlet port having a restricted opening, with the inlet port opening at least 2 times larger than the restricted outlet port opening. The valve includes components for opening and closing the inlet port in response to valve cavity pressure between the inlet and outlet ports. The larger inlet port relative to the restricted outlet port provides for rapid pressure buildup in the valve cavity when the inlet port is open which, in turn, causes rapid closing of the inlet port. The valve is capable of rapid cycling rates, highly effective for small refrigeration or cooling apparatus, as well as for controlling pressure in other applications requiring pressure regulation.

Pulsed operation control valve

The rate of water vapor sorption of an absorption cycle cooling and/or heating system using an aqueous alkali metal hydroxide solution as the working fluid is increased by adding at least 2 parts per million of a primary, secondary or tertiary aliphatic, cycloaliphatic or aromatic amine to the fluid.
