The use of freons as a working fluid in heat pipes of heat exchangers of ventilation systems

Most modern heat pipes operate with ammonia or water as the working fluid. In the last 10-15 years, the choice of refrigerant has been preferentially falling on halogenated hydrocarbons, such as chladones or freons, since ammonia is a hazardous substance. The article presents the results of calculations of the values of liquid mass flow rate and maximum heat transfer capacity of heat pipes using various freons.
