Question

which of these can cool air in summer, heat air in winter, and control the amount of moisture in the air? answer options: select one of four electrical heating system heat pump air conditioner radiator

Explanation:

• Electrical heating system: Only heats, no cooling or moisture control.
• Heat pump: Can cool in summer (by reversing cycle to act as AC) and heat in winter, and some models control moisture.
• Air conditioner: Cools and controls moisture but typically doesn't heat (except heat - AC combo, but heat pump is more specialized for both heating and cooling with moisture control).
• Radiator: Only heats, no cooling or moisture control. So the heat pump fits all three functions.

Heat pump
