What type of refrigeration system can switch between heating and cooling modes?

• A. Chiller
• B. Cooling tower
• C. Heat pump
• D. Refrigerator

Answer: (C)

A heat pump is designed to transfer heat from one location to another and can operate in both heating and cooling modes. In cooling mode, it absorbs heat from the indoors and releases it outside, similar to how an air conditioner functions. In heating mode, it reverses this process, extracting heat from the outside air (or ground) and transferring it indoors. This ability to switch between modes is what distinguishes heat pumps from other refrigeration systems that are typically dedicated to either heating or cooling but not both. Chillers, for instance, primarily focus on cooling large areas, while cooling towers serve to dissipate heat from a building or mechanical systems and do not provide heating. Refrigerators, like heat pumps, are designed for cooling but are not capable of switching to heating mode. Thus, the versatility of heat pumps in providing both heating and cooling makes them the correct answer to the question.
