Match List-I (Refrigerant) with List-Il (Application) and select the c...
List-I (Refrigerant) and List-II (Application) are given, and we need to match the refrigerant with its corresponding application.
List-I:
A. R-11
B. R-12
C. R-22
D. NH3
List-II:
1. Window type air conditioning system
2. Central air-conditioning system
3. Domestic refrigerator
4. Cold storages, ice plants
To match the refrigerant with its corresponding application, we can refer to the properties and characteristics of each refrigerant and its suitability for specific applications.
R-11 is a chlorofluorocarbon (CFC) refrigerant, which is primarily used in centrifugal chillers for large-scale air conditioning systems. It is suitable for applications such as central air-conditioning systems, making option (a) incorrect.
R-12 is also a CFC refrigerant, commonly known as Freon-12. It was widely used in domestic refrigerators and automotive air conditioning systems. Therefore, it is suitable for applications such as domestic refrigerators, making option (b) incorrect.
R-22 is a hydrochlorofluorocarbon (HCFC) refrigerant, commonly known as Freon-22. It is widely used in residential and commercial air conditioning systems, including window type air conditioning systems. This makes option (c) correct.
NH3, also known as ammonia, is not commonly used in window type air conditioning systems or domestic refrigerators. However, it is widely used in industrial applications such as cold storages and ice plants due to its high efficiency and low environmental impact. This makes option (d) correct.
Therefore, the correct matching is:
A. R-11 - 2. Central air-conditioning system
B. R-12 - 3. Domestic refrigerator
C. R-22 - 1. Window type air conditioning system
D. NH3 - 4. Cold storages, ice plants
Hence, the correct answer is option (c) 2 3 1 4.
List-I:
A. R-11
B. R-12
C. R-22
D. NH3
List-II:
1. Window type air conditioning system
2. Central air-conditioning system
3. Domestic refrigerator
4. Cold storages, ice plants
