Applications of Thermodynamics: Heat Pumps and Refrigerators
The electrically driven compressor (work input W) raises the temperature and pressure of the gas and forces it into the condenser coils that are inside the heated space. Because the temperature of the gas is higher than the temperature inside the room, heat transfer to the room occurs and the gas condenses to a

Heat energy and transfer: Specific heat capacity. | hvac machinery
Calculate the quantity of heat required to raise the temperature of 5 kg of water from 0°C to 100°C. Assume the specific heat capacity of water is 4200 J/ (kg °C). Quantity of heat energy, Q = mc ( t 2 – t 1) = 5 kg × 4200 J/ (kg °C) × (100 – 0)°C. = 5 × 4200 × 100. = 2100000 J or 2100 kJ or 2.1 MJ. Problem 4.
