Diagram of supplier the three patented stages microprocessor board and application of the condenser coil . The communicate through sensors , magnetic temperature heats up the 7.2 ° C air gradually to modulating valves , and others , so as to enable 18 ° C , and at the same time removing more the system to achieve a stable temperature
Stage 2 involves using the DX cooling coil approach was crude , it worked to a certain extent , moisture from the air to reach RH of 50 %. and 50 % RH to Operation Theater application . system which further cools the supply air to 12 ° C given that such technology was not available then . and 7.2 ° C dew point . The RH remains at 100 %, The Hybrid System has been made possible moisture content and 6.5g / kg , with the application with the This advent system of is the currently inverter available compressor in the , market of the DX Cooling Coil System . magnetic in that modulating : valve and microprocessor
Stage 3 involves a reheat system through control algorithm I . 2 suppliers . This hybrid in Malaysia system have adopts some job application of a condenser coil .

this article ’ s objectives are to highlight common available System systems technology currently available is still in in the infant market stage , it and the needs potential a breakthrough of the latest chilled for water the system coil to plus DX improve hybrid system on and . be available readily .
As the Hybrid System is still in its infant stage , it needs a breakthrough for the system to be improved and for it to be readily available .
The Hybrid System is made possible with the
