Consider the following statements
High condenser pressure in a refrigeration system can occur because
1. The water flow rate is lower than the desired value
2. Non – condensable gases are present in the system
3. of accumulation of lubricating oil in condenser
4. of low charge of refrigerant in the system
Oil these statements
(a) 1, 3 and 4 are correct
(b) 1, 2 and 3 are correct
(c) 1, 2 and 4 are correct
(d) 2, 3 and 4 are correct
