Decentralized ventilation with heating and cooling in one solution

Airmaster offers several concepts that combine decentralized ventilation with heating and cooling. Choose the solution that best suits the building's needs and requirements for comfort, energy efficiency and indoor climate.

Interaction between ventilation, heating and cooling

A good thermal indoor climate requires ventilation, heating and cooling to work together as one integrated system. When the installations are controlled independently of each other, they may work against each other, which can affect both comfort and energy consumption.

That is why Airmaster offers several concepts in which ventilation, heating and cooling are integrated into one complete solution. This provides simple control, a stable indoor climate and energy-efficient operation.

Below, you can read more about the different concepts and find the solution that best suits your project.

Heat or cool your room with an RC solution

With an RC solution (Room Conditioning), the inlet air can be heated or cooled according to the needs of the room, both in summer and in winter. Ventilation, heating and cooling are combined in one decentralized unit, and you control both the temperature and the air quality according to your preferences. The RC solution is available for AM 950 C and AM 1000.

AM 1000 RC

The fresh air first passes through the unit's heat exchanger and then through the RC module's heating-cooling surface, where it is heated or cooled before it is blown into the room. The module consists of a heating-cooling surface, a modulating control valve and a condensate tray with a float switch and a condensate pump. The module is water-based, so no refrigeration technician is required to install or maintain it.

The hot and cold water comes from a central supply in the building, e.g. a heat pump, a chiller or district heating. You choose the type and make yourself. With a heat pump, the unit can both heat and cool. A chiller provides cooling, and district heating provides heating. The size of the supply determines how many units can be connected. The pipes are routed to the water connections on the side or top of the unit.

In each room, you set the desired room temperature on the Airlinq® Orbit control panel or in Airlinq® Online. The unit then heats or cools the room to the set temperature by itself. The unit detects whether the supply is delivering hot or cold water and adjusts the water flow to the heating-cooling surface according to the temperature in the room. The RC module is controlled by the air handling unit's own control system, so there is no separate control box. With Thermal Airflow™, the inlet air slats are controlled automatically, so the air is directed downward during heating and up along the ceiling during cooling. This reduces the risk of draft.

Rooms in the same building can have different needs at the same time. By dividing the supply, e.g. by facade orientation, you ensure a good indoor climate in all rooms.

Cool with a CC solution

With a CC solution (Comfort Cooling), the inlet air can be cooled to below the outdoor temperature, so that the temperature in the room is kept down on hot days. The CC solution is available for AM 150, AM 500 and AM 800. The cooling module is mounted on the back of the air handling unit, where the intake and exhaust are located. The unit therefore becomes deeper by the depth of the module.

AM 800 CC

The cooling module has its own refrigerant circuit with an inverter-controlled compressor and uses the natural refrigerant propane, which has a GWP value of 0.02. GWP (Global Warming Potential) indicates how much a substance contributes to global warming compared with CO₂, which has a value of 1. Propane therefore has a far smaller impact on the climate than CO₂. The compressor adjusts the cooling capacity up and down according to demand. The condensate that forms during cooling is collected in a condensate tray with a float switch and drained away.

The heat generated during cooling is discharged with the exhaust air, so there is no outdoor unit and no hot or cold water supply. The unit and the cooling module only need power, a condensate drain and, if required, a network connection, so the decentralized principle is maintained. The main control system is located in the air handling unit, so the cooling module and the ventilation are controlled together.

The CC solution cools but does not heat. If you also need heating, see the RC solution or the AMX solution.

Heat and cool with an AMX solution

The AMX concept consists of an air handling unit with a built-in reversible heat pump that can both heat and cool. The heat pump uses the natural refrigerant propane, which has a GWP value of 0.02. It is a further development of the decentralized approach, where the same unit can ventilate, heat and cool your room. At the time of writing, the concept has only been developed for one unit, the AMX 4.

AMX solution

AMX 4

When you have an AMX 4 unit installed, you get the complete AMX concept. There are no extra modules or other items to purchase. The unit requires no external supply, so the decentralized principle is maintained for ventilation, heating and cooling alike. There are no noisy outdoor units, and the built-in compressor is so quiet that the unit can be used in rooms with even strict acoustic requirements.

With an AMX solution, the inlet air can be heated or cooled depending on the needs of your room, so the room temperature can be adapted to current needs both in summer and in winter. With an AMX solution, you can control the room's thermal indoor climate (heating and cooling) and the air quality (ventilation) according to your specific preferences. With Thermal Airflow™, the inlet air slats are controlled automatically, so the air is directed downward during heating and up along the ceiling during cooling. This reduces the risk of draft.

The unit only requires power, a condensate drain and, if required, a network connection. All other supplies to the unit and the built-in heat pump come from the air handling unit's control system. The unit's built-in power supply is single-phase, so no costly electrical installation is necessary.
