False.
They were initially thought to be stable and harmless as they had low reactivity (hence stable), were non toxic and non flammable and so found wide spread use as refrigerant gasses (heat exchangers). However it was later discovered that in the upper atmosphere they were broken down by photons (light) to liberate Chlorine and helped to cause the break down of ozone to O2 which is a much less effective barrier to UV leading to the creation of "holes" in the ozone layer.
What else can I help you with?
Heat exchangers are used in refrigerator or not?
Yes, heat exchangers are used.
Name the types of heat exchangers used as super-heaters?
The types of heat exchangers commonly used as super-heaters are shell-and-tube heat exchangers and plate heat exchangers. These heat exchangers are designed to efficiently transfer heat from the combustion gases to the steam in power plants, increasing the temperature and improving the efficiency of the system.
What are the problems of heat exchangers?
blocked lines and wear of lines are the most important problems of heat exchangers.
What is the different between plate heat exchangers and tube heat exchangers?
Plate heat exchangers use flat plates to transfer heat between two fluids, providing a large surface area for efficient heat transfer in a compact design. Tube heat exchangers utilize tubes to facilitate heat exchange between fluids, offering a more traditional and versatile approach to heat transfer applications. Plate heat exchangers are typically more efficient and cost-effective for certain applications compared to tube heat exchangers.

What is heat duty?
heat duty refers to the heat exchangers. heat duty of the heat exchangers is defined as the amount of heat transfered of 1kg of hot fluid to the 1 kg of cold fluid in one hour.
What is fouling factor this factor used in heat exchangers?
Fouling factor is essentially used in determining the efficiency of the heat exchangers. Fouling factor is obtained from service (product) on either side of tubes and material of tubes. It basically represents corrosion of heat exchangers tubes which affects efficiency of heat transfer.

Do heat exchangers cause a fire hazard in apartment buildings?
Heat exchangers can be used in many things like space heaters, refrigeration and air conditioning. Heat exchangers by themselves are likely not a significant fire hazard. Space heaters can create a threat of fire if not watched and used properly.
What does Exergy LLC manufacture?
The company Exergy LLC manufactures heat exchangers. Heat exchangers are items such as parts for boilers, engines and furnaces. Some of their products are used by Shell.
