6.4.1.1 Duct connections
When Topvex SoftCooler have been joined together with the two air handling unit parts it is in total 5 duct connections on top of the unit: Outdoor air, Supply air, Extract air  and 2 Exhaust air. Duct connections can be done on two different ways, with or without a by-pass-function for the exhaust air.
For duct connection without by-pass function on the exhaust air only 4 duct connections are used. The exhaust air duct are then to be connected to the exhaust air duct  connection on the Topvex SoftCooler module. The exhaust air duct connection on the air handling unit must be locked with the Topvex SoftCooler included locking plate.
For duct connection with “By-pass” function on the exhaust air all 5 duct connections are used. The exhaust air duct are then to be connected both to the Exhaust air duct  connection on the Topvex SoftCooler module and to the one on the air handling unit.
N.B. Motorized spring return dampers must be mounted on each exhaust air duct connection.

6.4.1.2 Condensation and Heat Insulation
Outdoor air duct and discharge ducts must always be well insulated against condensation. Correct insulation installation on ducts connected to the unit is especially important.  All ducts installed in cold rooms/areas must be well insulated. Use insulating covering (minimum 100 mm mineral wool) with plastic diffusion barrier. In areas  with extremely low outdoor temperatures during the winter, additional insulation must be installed. Total insulation thickness must be at least 150 mm.

Caution

• If the unit is installed in a cold place make sure that all joints are covered with insulation, and tape well
• Duct connections/duct ends should be covered during storage and installation
• Do not connect tumble dryers to the ventilation system

Function Description

Fig. 11 Without by-pass, left hand unit

Fig. 12 With by-pass, left hand unit

7.1 General
Control unit E28 (UC) senses the temperature via the extract temperature sensor (ETS) and then keep the set extract temperature by sequence controlling the compressor  (CPR), heat exchanger (HE) and hot water- /electrical heater (HWL/H, ELH). The temperature sensor in the supply air (SS) is min. and max. limiting the supply air  temperature.
7.2 Cool recovering
Exchanger (HE) will automatically start to recover the cold in the extract air when the extract air is colder then the outdoor air.
7.3 Power control
The compressor (CPR) are step-less controlled between, in the frequency converter (FC), set minimum and maximum frequency.
7.4 Power limitation
The frequency converter (FC) is continuously sensing the condensing pressure via the high pressure sensor (HPS) and gradually slows down the speed of the compressor  (CPR), if the pressure exceeds the set limitation value. This is done to avoid a high pressure alarm.
7.5 By-pass function (option)
To reduce the energy use for the extract fan when there is no cooling demand the exhaust by-pass damper (accessory) is opened and thereby the exhaust air does not pass the  condenser (CO). At stopped unit all dampers are closed.

Note:
This instruction contains functions for the Topvex SoftCooler TR, for a complete description of functions see “Topvex SR 09,11, TR 09-15 Installation instruction”
