A refrigeration system is installed in a cold storage facility to maintain a constant temperature of -6°C. The cold storage facility has 5 five storage chambers. The heat from outside enters each storage chamber at a rate of 90000 kJ/hr. All the electrical appliances inside the cold storage facility generate heat at a rate of 38000 kJ/hr. The refrigeration system has a COP of 2.6. Determine the work required (in kW) by the refrigeration system to maintain a constant temperature of -6°C inside the cold storage facility.
