Which system is designed to allow simultaneous heating and cooling?

A heat recovery system is engineered to enable simultaneous heating and cooling by transferring heat from one area to another. This type of system typically operates using a heat exchanger that captures waste heat from a cooling process and repurposes it for heating needs, thereby efficiently utilizing energy.

In a heat recovery system, cooling and heating can occur at the same time in different zones. For example, while one part of a building is being cooled, the heat extracted can be used to warm another part, which increases overall efficiency while reducing energy consumption. This feature is particularly advantageous in large commercial spaces where different areas may have varying thermal requirements.

The other system types mentioned do not have this dual capability. A single-zone system is designed to control the temperature for a single area, and a multi-zone split system typically allows for heating or cooling in distinct zones but not simultaneously. An evaporative cooling system focuses on using water to cool air and does not provide heating capabilities. Thus, a heat recovery system stands out for its ability to manage both heating and cooling needs efficiently at the same time.
