AI Technical Summary

Technical Problem

Existing absorption chillers have shortcomings in waste heat recovery efficiency and cost, making it difficult to effectively recover a large amount of heat with relatively low cost.

Method used

An absorption chiller unit was designed, comprising first and second solution circulation loops. By adding a low-temperature generator and an absorber, the COP is improved, and the saturated vapor pressure of the evaporator is made higher than that of the low-temperature generator, allowing the recovery of external heat sources at different temperatures.

Benefits of technology

It enables flexible utilization of waste heat sources at different temperatures, improves the efficiency and flexibility of waste heat recovery, reduces the temperature range of waste heat sources, and enhances the applicable operating conditions of the unit.

Abstract

The utility model discloses an absorption type unit, absorption type unit medium temperature absorber, low temperature generator, condenser and medium temperature generator form first kind heat pump module, namely approximate and current technology first kind heat pump unit, and the application can effectively improve the COP of absorption type unit through the additional absorber and low temperature generator, and because the saturation steam pressure of evaporator can be higher than the saturation steam pressure of low temperature generator, make the temperature range of first waste heat source be wide, and absorption type unit can have more working condition. The absorption type unit has two solution circulation loops, can recover different temperature external heat source, can flexibly use multiple external waste heat sources.
