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.

Description of Related Art[0007]The conventional absorption chiller cycle uses water as the refrigerant and Lithium Bromide as the absorbent [1]. A solution pump transfers the lithium bromide solution to a tube heat exchanger for preheating. A generator brings the solution to a boiling state and sends the refrigerant vapour upwards into the condenser leaving the concentrated Lithium Bromide behind. This concentrated solution liqu...

Benefits of technology

The present invention provides a new method in absorption cooling system that eliminates the consumption of heat during the evaporation process, making it environmentally safer. The method employs less component parts, reduces the chilling cycle, and improves energy efficiency of traditional absorption air conditioners. The invention also uses environmentally friendly liquids, such as distilled water and lithium bromide, which are recyclable and contribute minimal harm to the environment.

Problems solved by technology

Mainstream absorption air conditioners have limited use cases due to their high electrical energy consumption.

As an example, during peak electrical consumption hours in the hot summer season, in which air conditioners are in operation across the city, electrical energy demand increases to an extent that could lead to regional blackouts if electricity supply is not matched.

On the other hand, many families cannot afford the high cost of maintaining typical air conditioners which consume at least 2 kW of electrical power.

Many organs, such as hospitals, have to dedicated a large portion of their annual budget towards electricity costs of maintaining large air conditioner systems, which results in reduction in revenues.

In overall, typical air conditioners have limited use cases due to their heavy weight and large sizes, as a result of a high parts count, and high energy consumption, which is nearly 4 times more than today's more innovative air conditioners.
