Max.e3
Damvent
max.e3 is an autonomous module heat recovery ventilation unit containing an biult-in heat pump, automation, and a control system.
max.e3 - Hybrid AHU with "2 stage thermodynamic heat recovery technology"- recovering up to 100% of the extract heat/cool/humidity, achieved - "consecutively" in 2 stages:
1st stage - "passive heat recovery" - the sorption rotary heat exchanger, recovers more than 70% of the heatig/cooling and humidity.
2nd stage - "active heat recovery" - the evaporator/condenser of the air-to-air heat pump recovers the rest up to 100%
max.e3 is designed for Every Climate from -25°C to +60°C.
max.e3 is suitable for Every Application where 100% fresh air is needed, by means of covering all possible air treatment processes:
- Filtration
- Heat recovery
- Heating
- Cooling + Dehumidification
- Proces Ventilation
Every Installation - suitable for all types of mounting, indoor (machinery rooms, technical floors, etc.) and outdoor
100% Plug and Play - standalone "one-piece" unit, which only needs a duct system and power supply for its start up.
High reliability and reduced installation costs, achieved by 100% factory tests - each unit is tested under factory conditions. The test includes:
- Leakage check
- Vacuuming and loading the system with the exact refrigerant quantity
- Functional testing of all fans and compressors
- Vibrations
- Loading the controller's software
- Temperature and pressure checks
- Setting up the required air flow
- Recording all parameters of the unit on the test list
COP/SCOP/SPF - A conventional air-cooled heat pump uses the ambient air for the evaporation process and during the winter this air can reach temperatures of -10°C, -15°C or even -20°C. Extracting heat from the ambient air is an inefficient process. In comparison, max.e2 uses the extract air from within the room. Under normal conditions, this air ranges in temperatures from 20÷24°C. Firstly, 70÷80% of the heat is recovered in the rotary heat exchanger and then at a temperature between 1÷6°C, the air enters the evaporator of the heat pump, thus recovering the other 20÷30%.
Using this method, Damvent achieve a COPsystem of 10 or more and avoid frost formation on the evaporator (which commonly occurs in all conventional heat pumps).
