Daikin has an extensive range of inverter and non-inverter heat pumps for both the domestic and commercial markets. Non Inverter
These operate on a start/stop principal of heating similar to other conventional heating systems. For example, if you programme the heater to produce 23°C for the area, it will achieve this and then switch off. The result will be that the temperature across the space will drop and the process will then have to start all over again, using more power to reheat the area.
The inverter works like an accelerator on your car – gently increasing or decreasing power as required. It reaches the desired temperature and then maintains it – during winter 24 hours per day and at a temperature that suits you. This method of operation not only produces a very acceptable climate in which to live and work but also produces considerable savings in operating costs.
1. It uses 30% less energy a year than the ordinary non-inverter method
- The start/stop cycle is repeated less frequently, reducing energy loss at start-up.
- As the room nears the set temperature, capacity is automatically throttled down.
- Operating efficiency is high because capacity is lowered to match the room temperature if the outside temperature becomes milder. For instance, when heating, the energy-saving effect is prominent when the outside air temperature is above 5°C
2. The heating/cooling capacity is up to 1.5 times that of ordinary non-inverter models
- At startup, up to 1.5 times higher full scale output is produced compared with an ordinary heat pump air conditioner. It takes only two thirds the normal time required to bring the room temperature to a satisfying level.
3. There is less temperature fluctuation and greater comfort
- The capacity is finely adjusted to match the changes in the room temperature, providing constant comfort.
