3. AHU CONSTRUCTION

- The MCKT-HPX AHU's casing is made of framework casing made of anodized aluminum profiles and plastic cor­ners, and galvanized steel sheet and non-flammable mineral wool which provides appropriate thermal and acoustic
insulation. The casing panels are 50 mm thick.

Inspection panels are equipped with handles
and are mounted to the framework with one­and two-side clamps
The AHU's framework is equipped with han­dles enabling suspension of the unit to ceiling
with bars.

Picture no. 2 Inspection panels

AHU's side masking covers can be arranged in
different ways, enabling 16 combinations of ventila­tion port arrangements.

Picture no. 3 Side covers masking the ventilation ports

- MCKT-HPX AHU internal equipment: two G4-class cartridge filters, plate cross-flow heat exchanger, two axial­radial fans with direct drive and complete sets of heat pump: air-air with cooling system and two CuAl exchangers.
The heat pump enables cooling of supply air in summer and heating it in winter.

In the lower part of the inspection plate there are connections (hose connectors) for draining condensate water from
the cross-flow heat exchanger and cooler outside the AHU.

- The MCKT-HPX AHU is equipped with complete system of power supply and control system. The RZS box is at­tached to the AHU side wall. The AHU is directly controlled by the control panel. Information regarding operating the
unit are attached.

4. OPERATION PRINCIPLE

The MCKT-HPX AHU can operate only with the cross-flow exchanger or with the cross-flow exchanger and heat
pump.
The most beneficial external air temperate enabling the highest heat pump efficiency for cooling is above -5°C. In
case of lower temperatures the control system switches off the cooling system and the unit operates in heat recovery
mode only with the cross-flow exchanger. To ensure proper operation of the heat pump, in order to heat up air to
required temperature, it is necessary to use preliminary NGS water heaters or NGE electrical heaters which heat up
external air up to -5°C.

4.1 THERMAL BALANCE

Compact MCKT-HPX AHU equipped with the cross-flow heat exchanger and heat pump forms a high-performance
heat recovery system for a ventilated room. However ventilated rooms have to be source of heat in order to enable
heat recovery. That is why at the stage of designing heating and ventilation system it is necessary to carry out the
room's thermal balance – a balance of profit and loss. Ventilated rooms should be equipped with independent heat­ing provided by radiators, floor heating or other heating method, while the MCKT-HPX AHU should only take care of
heating up the supply air.
