In heat recovery systems, what can be unique about the operation of multiple indoor units?

In heat recovery systems, the ability for one indoor unit to heat while others cool at the same time is a key feature that showcases the versatility and efficiency of these systems. This operation is made possible due to the design of heat recovery systems, which allow for the transfer of heat from one area to another efficiently.

When one indoor unit is in heating mode, it extracts heat from the refrigerant, which can be released to another indoor unit that is operating in cooling mode. This simultaneous operation is particularly advantageous in scenarios where different zones within a building have varying heating and cooling requirements. By allowing one unit to heat while others cool, the system optimizes energy use and improves comfort across different spaces, making it a flexible solution for diverse environments.

This capability distinguishes heat recovery systems from conventional systems that require all units to operate in the same mode, thus enhancing their appeal for commercial and residential applications where varied temperature control is essential.
