C. Radiator
D. Air conditioner

Answer :

Final answer:

The heat pump is the best option as it can cool air in summer, heat air in winter, and control humidity levels. It works by transferring heat and can also dehumidify the air in the process. This makes it a versatile and effective solution for managing indoor climate throughout the year.


Explanation:

Temperature Control and Humidity Management

Among the options provided, the heat pump is the device that can cool air in summer, heat air in winter, and control the amount of moisture in the air. A heat pump works by transferring heat from one place to another, making it versatile for both heating and cooling purposes.

How a Heat Pump Works

During the summer, a heat pump can operate in cooling mode, whereby it extracts heat from the indoor air and transfers it outside. In the winter, it reverses the process by absorbing heat from the outside air and transferring it indoors, effectively heating the space. Furthermore, heat pumps can dehumidify the air as they operate by lowering the air temperature, causing moisture to condense, which can improve indoor air quality.

  1. Cooling in Summer: Extracts heat from inside to provide cool air.
  2. Heating in Winter: Draws heat from outside to warm indoor spaces.
  3. Moisture Control: Reduces humidity by condensing excess moisture.
