  • Page 10 2.2.2 Rotary heat exchanger - Principle / Construction The construction of the rotating heat exchanger used into the RHE consists of alternating layers of flat and corrugated aluminum foil, which form a spiral from the center. This results in a defined structure of small triangular flutes. Supply and exhaust air each pass through half of the wheel in counter flow directions. The rotor exchanger is a rotating transfer media. It temporarily takes up the heat from the warm air stream and releases it in the colder air stream. Purge sector: A bleed sector allows flushing stale air present in the “honeycombs” before the wheel passes in front of the fresh airflow.

The RHE dual flow air handling units can be handled by a pallet transporter, a forklift, or a crane. The han- dling machines will be adapted to the load and the lifting conditions. In all cases, the lifting will be done at the device’s base. The centre of gravity is located at the centre of the unit. The device must be carefully manipulated only in the horizontal position. Ø 50 mm. holes are provided for in the frame to allow passing a pipe to hook the slings. To avoid deteriorating the unit’s envelope, long length slings and lifting beam spacers must be used. In case a forklift / pallet transporter is used, the forks should be long enough to avoid pushing in the lower panel. Position the forks low enough so as to not damage the doors. Lift gently.

The RHE HD / VD units are designed for an installation inside the building. Only the HD OI versions delivered with a roof can be used outdoors. In all cases, provide the ducts, connection accessories, heater antifreeze protection and antivibration equipment. In heavy snowfall zones, an additional protection must be provided for. It is important to provide enough space (Z minimum) to allow opening the doors, commissioning and main- tenance (filters, fans, heat exchanger).

  • Page 53: Airflow Control Fan

    7.2 Airflow control Fan Airflow management can be carried out according to 3 control modes: CAV, VAV, COP. Whatever mode is selected, each fan suction pavilion (extraction and supply) is equipped with a pressure tap and connected to a pressure sensor. The flow rates resulting from the pressure measurements are calculated by the regulator, according to a coefficient K specific to each fan. • The DO1 digital output corresponds to the supply fan running command and can be used for acces- sory operation linked to the operating status of the fans (for example starting a DX unit if the supply fan is running). • Analog output AO4 corresponds to the 0-10V control signal sent to the supply fan. •...
  • Page 54 Independently, a BOOST (extra m /h) airflow can be programmed in the form of a fixed airflow for extrac- tion and supply. • Digital input DI5 = Start/stop. • Digital input DI6 = forcing GV - forcing of the max flow rate set for the max signal. • BOOST (extra m3/h) selection can be done from the remote control. To perform a BOOST forcing via a digital input, it is necessary to reparametrize a digital input (DI1 for example) and assign it the "Additional alarm 7" function. When closing this digital input, an “External BOOST forcing” message will appear on the main screen. • A fourth flow set point for "night free cooling” overventilation can be entered via the remote control, in the form of an offset of the high-speed flow GV (see free cooling for operation) 7.2.3 Operation at constant pressure COP on extraction or supply mode Recommended mode in multi-zone configuration associated with terminal airflow modulation systems.

  • Page 55: Temperature Control

    7.3 Temperature control 7.3.1 General principle The temperature set point as well as the temperature regulation mode are entered via the touch screen. The supply or ambient temperature is maintained at the set value by acting on the controller outputs (hea- ting/exchange/cooling), a single PI loop is used. The exchanger is considered to be the first potential source of heat or cooling even before the batteries. For RHE fitted with a standard rotary heat exchanger (1 speed), the wheel is controlled in binary mode (on or off). For RHE equipped with a sorption exchanger, the rotation speed is variable, proportional to a 0 - 10V si- gnal. By varying the speed of rotation, it is therefore possible to modify the efficiency of the exchanger to reach a given temperature set point.

  • Page 56 7.3.2 Temperature control modes The temperature regulation can be carried out according to the following 4 modes: • Supply air control at constant temperature The supply air temperature is maintained at the set value by acting on the exchanger outputs, hot output and cold output. The setpoint is adjusted using the display and number keys. The user set point for the mode is entered in °C in the settings menu. • Supply air control at constant temperature with outdoor temperature compensation The supply air temperature setpoint is adjusted according to the outside temperature according to a compensation law made up of 8 factory preset setpoints. The supply temperature is maintained at the set value by acting on the exchanger, internal coil, exchan- ger, external coil outputs.

  • Page 58 If ALL the conditions are fulfilled, the cooling by overventilation starts. It remains on for 3 minutes to ensure that the temperature measurements are representative (by creating air movement in the ducts). After three minutes, the controller checks for shutdown conditions. Stop conditions: • The outside temperature is above 18°C or below 10°C (risk of condensation station). • The return temperature is below 18°C • The time programs (timer) for normal speed, normal override and control are “On”. • It is past 7:00 in the morning. If at least one of these conditions is fulfilled after the first three minutes of operation, then the overventila- tion is stopped. When the over-ventilation function is active, the fans run: • In CAV at the speed set for high speed(GV) + an offset in m /h (settings entered in the CAV settings menu).

    7.9 MIB 0-10V – Mixing box The mixing box is mainly used in mixed ventilation and heating installations. It will make it possible to operate in recycling mode during periods of non-occupation and in all fresh air during maximum occupancy of the premises. Operating principle: The mixing box is fitted with a CO2 sensor (SCO2 A-010 400-1100ppm) which continuously measures the level of CO2 contained in the extracted air, it sends a proportional signal to the damper servomotors to open them more or less depending on the indoor air quality.

It is possible to set different time programs for each day of the week, plus a specific time program for ho- lidays and vacations. Time slots (time prg 5) can be programmed for air recycling if the unit is equipped with a recycling box. It is possible to define up to 24 holiday periods. A vacation period can last from 1 to 365 days. The time programs for holidays have priority over the others. Clock setting: Only the operating ranges are programmed (outside these ranges the unit is stopped). The installer can define 3 operating ranges: reduced speed ECO, high speed GV, boost.
