 ===== Dehumidification =====
-In humid areas where dehumidification is required but no ERV is possible due to hazardous extract air, a very efficient dehumidification system for large air flow must be devised. This will- and can without hygienic issues- employ the most efficient heat recovery to reheat the dehumidified air with the heat from the incoming, moist air. The condenser of the dehumidifier in the exhaust air path can be operated in wet mode, after filtering and UV disinfection of the condensed water.

 ===== Wastewater disinfection =====
-Some biological laboratories may require thermal disinfection of waste water. In a conventional system the water’s high thermal capacity will cause a very high energy demand, and commercial systems already feature some form of heat recovery. However, for disinfection only a high level of temperature is required, not heat. If the heat recovery is sophisticated enough to achieve a high heat recovery rate and heats up the input water with the heat of the water that is simultaneously displaced from the tank and if the system is well insulated, then only a minimal heat loss needs to be covered. A high-temperature heat pump can do the job and transfer heat from the run-off back to the tank.

 As commercial units may not be satisfactory, trigger the work on a bespoke system early on. [[planning:non-residential_passive_house_buildings:swimming_pools:energy_efficiency_in_public_indoor_swimming_pools|Indoor swimming pool technology]] has come a long way in heat recovery from waste water in recent years and may offer interesting solutions.
