Ventilation system for schools in the picture

TKI project consortium, TNO, Lucam-air, VFA Solutions: SchoolVent for a healthy learning environment!

TNO has started the Schoolvent project for the development and practical test of a ventilation system suitable for (renovation of) schools and daycare centers with 80% lower energy costs for cooling and filtering. Smart Sensoring must be built into this system to report deviations from a class A indoor climate.

The applied cooling and filtering techniques make an important contribution to the reduction of the required cooling and ventilation energy in buildings and thus make energy-neutral or energy-supplying buildings possible. In addition to schools and daycare centers, the largest market is foreseen for offices in the longer term.

Simple and scalable

The standard configuration is simple control of two fans and heat recovery with a 0-10V signal. Pre-programmed options and automatic configuration with QuickPlug™ modbus components make it easy to fulfil a clients needs for more advanced fan regulation, filter monitoring or temperature regulation with a 0-10V controlled heating and/or cooling surface.

Free OJ Air Cloud®

When AHC-3000 is connected to the internet the user has free access to central monitoring and optimisation of the operation from a personal OJ Air Cloud® account. Access can be shared with others, e.g. a service partner for quick and effective service.

BasicBMS and remote units

In buildings with decentralised ventilation there are many ventilation systems to service and maybe several in the same room. With BasicBMS 25 rooms can easily be monitored from a common 3.5” panel, and the satellite function automatically coordinates the operation of 14 remote units in every single room.

Intuitive touch operation

Want to change the temperature setting? Then simply tap the temperature shown on the screen and enter the new setpoint. It has never been easier, and the entire menu system is designed according to the same principle.

No secrets

All values are visible to everyone, and a complete overview of system operation is provided for users in clear displays. Settings which are only of relevance for installers and service technicians are, however, password protected.

Simple installation

AHC-3000-HMI-35T is connected to the OJ Air AHC 3000 via Quick Plug™ Modbus, eliminating time-consuming installation faults and troubleshooting. The software is automatically updated to the latest AHC-3000 version. You therefore always have the right version in stock, because there is only one.

• OJ Air AHC-3000 compatible
• Intuitive user interface
• 3.5” colour touchscreen
• Countersunk wall mounting

TNO, Lucam en VFA develop a new ventilation system for schools.

TNO, Lucam en VFA solutions develop together a new ventilation system for schools. Resent study’s of the Dutch TNO (technological institute) reviels that new and renovated schools with new insulation have heat problems in the summer. Also the monitoring of the ventilation is needed mentioned in the report. Also fine dust in schools is a problem that needs attention.

As team we started a TKI project. The solution for the problems as, CO₂, temperature overrides, fijndust and monitoring arefound, developed or made. A field test will give te proof. The Jordan college in Zeist was willing to help out. The test setup is almost ready. The system will run comming year and data will be collected. We keep you posted! Emmeloord 6-11-2019.

HCP E en HRW E, ventilation units low pricing.

Lucam introduces the new line ventilation units, low pricing, fast delivery. The HCP E, with counterflow exchanger. The HRW E with heatrecovery wheel.

The HCP E and HRW E can get modulair extensions like heater, cooler, change over, heatpump and sound attenuator. With this new line we also introduce the new controler of OJ Electronics. The new controller, the AHC 3000, is modern controller standard with cloud function. All configurations are configurable in our selectieprogram. Emmeloord, 6-11-2019
