Context

In an era in China when the structure and moral values of society are changing, BROAD has retained moral baselines such as environmental protection, respect for intellectual property rights, no price gouging, no predatory competition, no tax evasion, no bribery, etc. BROAD has placed morals and ethics as a top priority.

At the same time, in an era of global warming, environmental degradation and ozone depletion, BROAD specializes in non-electric chillers powered by clean and recyclable energies. BROAD chillers also use non-polluting refrigerant. The company resists the temptation of electric chiller market. Protecting the environment is more important than profit.

Objectives

- To protect the environment by creating non-electric air conditioning systems

APPROACH

The cooling principle:

The input heat energy heats LiBr (Lithium Bromide) solution to generate vapor, which is then condensed into water by cooling water. When the refrigerant water enters evaporator (in high vacuum condition), its temperature goes down immediately. And it is sprayed over the copper tubes to make cooling. The water absorbs heat from air conditioning system and evaporates, then is absorbed by concentrated LiBr solution from the generators. The cooling water takes away the heat and rejects it into the air. Diluted solution is pumped into HTG and LTG separately to be heated to begin the process all over again

The heating principle:

The input heat energy heats the LiBr solution. The vapor produced by the solution heats the heating water or hot water in tubes, while condensate returns to the solution to be heated and the cycle repeats.

As "separate heating" is adopted, the heating cycle becomes very simple, just like a vacuum boiler. Therefore, the life span of the chiller can be doubled.

A separate heat exchanger can provide dedicated hot water while cooling or heating operation is stopped.
