An absorption refrigerator is a refrigerator that uses a heat source to provide the energy needed to drive the cooling process. Solar energy, burning a fossil fuel, waste heat from factories, and district heating systems are examples of convenient heat sources that can be used.
The acute toxicity of ammonia is a major consideration in the safe design and operation of refrigeration systems. Although the odour of ammonia can be detected by smell at concentrations above 5 to 10ppm people who are used to it can work without discomfort in concentrations of approximately 100ppm.
Understanding the differences among the three types of ammonia refrigeration systems and how each works is a necessity for every technician that works on them.
It can explode if released in an enclosed space with a source of ignition present, or if a vessel containing anhydrous ammonia is exposed to fire. Fortunately, ammonia has a low odor threshold (20 ppm), so most people will seek relief at much lower concentrations.
2 Σεπ 2024 · An ammonia refrigeration system consists of several key components that work together to transfer heat efficiently: Compressor: The compressor is the heart of the system, responsible for compressing the ammonia gas, increasing its pressure and temperature.
8 Αυγ 2024 · Ammonia is widely used in industrial refrigeration, particularly in food processing, cold storage, and ice rinks. Its efficiency and capacity make it ideal for large-scale applications, especially in temperature ranges from -40°C to 2°C (-40°F to 35.6°F).
prepare an effective emergency plan for workplaces with anhydrous ammonia-based refrigeration systems. The guide includes information on the unique hazards presented by ammonia gas and its use in refrigeration, and relevant duties that apply under the work health and safety (WHS) legislation.
