ECONOMIZER FOR AN INTERMITTENT ABSORPTION REFRIGERATION SYSTEM

摘要

An economizer for a solar powered intermittent absorption refrigeration system improves the coefficient of performance of the refrigeration system. The economizer recovers waste energy rejected by an absorber during an absorption process, stores the waste energy, and supplies the waste energy to a generator during a generation process, thereby reducing the amount of energy input needed to operate the system.

主权项

1. An intermittent absorption refrigeration method, comprising:
pressurizing a strong absorbent-refrigerant solution in a generator/absorber by transferring thermal energy into the strong absorbent-refrigerant solution out of a heat-transfer fluid stored in an economizer; pressurizing the strong absorbent-refrigerant solution in the generator/absorber by transferring thermal energy into the strong absorbent-refrigerant solution out of a fluid heated by a thermal collector; then heating the pressurized strong absorbent-refrigerant solution to produce a first refrigerant vapor and a weak absorbent-refrigerant solution in the generator/absorber by transferring thermal energy into the strong absorbent-refrigerant solution out of the fluid heated by the thermal collector; condensing the first refrigerant vapor in a condenser by rejecting thermal energy out of the first refrigerant vapor to produce a liquid refrigerant; storing the liquid refrigerant in an evaporator; depressurizing the weak absorbent-refrigerant solution in the generator/absorber by transferring thermal energy out of the weak absorbent-refrigerant solution and into the heat-transfer fluid stored in the economizer; cooling a refrigerated volume by evaporating the liquid refrigerant into a second refrigerant vapor in the evaporator; and absorbing the second refrigerant vapor into the weak absorbent-refrigerant solution to produce the strong absorbent-refrigerant solution.
