Piezo Electric and High Voltage Absorption Cooling System

Abstract

The ever increasing cost of electricity has become a main area of concern for the indoor climate control business due to the fact that conventional absorption cooling devices suffer from a very high power consumption ranging from 2 kW to tens of kilo Watts. The high power consumption of a typical absorption coolers comes from the operation of the boiler which is used to heat the Lithium Bromide (LiBr) solution, as well as the chiller pump and pipings. This paper presents a novel solution for eliminating the need for hot steam to evaporate the Lithium Bromide (LiBr) solution by incorporating piezoelectric modules to generate cold LiBr vapour in the generator tank. This further simplifies the absorption cooling mechanism by eliminating the need for a cooling tower and a heat exchanger and reduces the overall size and dimensions of the device, without a reduction in cooling power.

What we claim are: 
     
         1 . An absorption cooling system, comprising: a generator with piezoelectric modules operating at 5 MHz which are used to evaporate the Lithium Bromide solution, and charged metal plates up to 10 kV, thereby removing the Lithium Bromide salt and allowing the water vapour to enter the evaporator water pump. 
     
     
         2 . The absorption cooling system of  claim 1 , wherein the piezoelectric modules, oscillating at 5 MHz, evaporate the Lithium bromide solution without the need for applying heat. 
     
     
         3 . The absorption cooling system of  claim 1 , wherein the high voltage plates are used to separate the Lithium Bromide salt from the water vapour. 
     
     
         4 . An air conditioning system, comprising: A tank for the evaporation of diluted Lithium Bromide solution and a second tank containing the evaporator and the absorber of the system; containing multiple pipes for direct air cooling. 
     
     
         5 . The method of  claim 1 , wherein the air to be cooled is directly passed through the evaporator pipes causing it to lose heat; as opposed to conventional methods of water chiller systems.
