The amount of heat absorbed in the evaporator is equal to the heat:

The correct answer reflects the principle of conservation of energy within the refrigeration cycle, particularly as it pertains to the relationship between the evaporator and condenser sections. In an HVAC system, the evaporator is responsible for absorbing heat from the space that needs to be cooled. This absorbed heat translates into the energy that is effectively removed from that space.

As the system operates, the heat absorbed by the evaporator must balance with the heat expelled by the condenser, adjusted for the energy consumed during the compression process. The heat given off by the condenser results from the heat absorbed by the evaporator and the additional energy input from the compressor during the compression stroke. Therefore, the heat absorbed in the evaporator equals the heat released by the condenser minus the heat of compression, which accounts for the work done by the compressor to circulate the refrigerant.

This principle illustrates the dynamics of heat transfer in the refrigeration cycle and emphasizes the conservation of energy, ensuring that all the heat absorbed in the evaporator is accounted for in the system's total energy flow. Understanding this relationship is crucial for efficient system design and troubleshooting in commercial air conditioning applications.
