Here is the explanation of the selection and material by taking the implementation case as an example to working medium (dense binary solution):
Fan engine room internal temperature is at 40 DEG C to 80 DEG C or so at present, and still ammonia more common in current practice
Aqueous solution and lithium-bromide solution.Below by the property for comparing both working medium pair, chooses and the design adaptive power conservation is suitble to dissipate
The working medium of hot systems compares.
1. the compound that lithium bromide is made of halogen and alkali family element, such compound chemical property is stablized, no
Easily volatilizees and decompose in air；Its physical property is good, non-toxic, white solid, boiling point are as follows: 1265 DEG C.
2. ammonia spirit is a kind of colourless gas, there are strong impulse odor liquids, the heat absorption capacity of ammonia is larger, thermal conductivity
Can be good, the boiling point of ammonia is -33.4 DEG C, and boiling point is lower.
Lithium bromide is as absorption type refrigeration working medium clock synchronization, and water is refrigerant, and boiling point is 100 DEG C, and wind power generating set
Temperature in cabin is generally between 30 DEG C to 80 DEG C, and ammonia spirit will evaporate gas at 36 DEG C, therefore the design
Working medium needed for wind power generating set adaptive power conservation cooling system is to being chosen as ammonia spirit.Because ammonia spirit has corrosion
Property, when ammonia spirit is elected to be binary solution, system equipment can choose the resistant materials such as aluminum alloy materials or 304 stainless steels.
