Condenser capacity is typically sized larger than evaporator capacity by which of the following statements?

• A. Yes
• B. No
• C. Only in certain systems
• D. It varies with system type

Answer: (A)

In a vapor‑compression cycle, the condenser must reject the heat that was absorbed by the evaporator plus the heat added by the compressor work. In other words, the total heat rejected by the condenser is Q_H = Q_L + W. Since the compressor work (W) is always positive, the condenser ends up handling more heat than the evaporator removes from the refrigerated space. That’s why condenser capacity is typically larger than evaporator capacity. If the evaporator handles 4 kW of cooling and the compressor adds 1 kW of heat, the condenser must reject about 5 kW. The exact amounts vary with conditions, but the general relationship holds, so the statement is true.
