Cheras Rehabilitation Hospital:
Kuala Lumpur, Malaysia
A First of its kind to get the RH right on Day 1
IAQ problems caused by mold and fungus take a more serious form when they happen in a health care facility.
Very often the patients in the hospitals have low resistance to infection and there are strong chances that they pick up infections other than what they came to the hospital to be treated for. This is what has been called ‘Hospital Acquired Infections’ or HAI.
In past, several hospitals and clinics had to be shut down for several months for de-comtamination of buildings to make them safer for patients.
Mr. Pua, the consultant in-charge of the design the air conditioning system of the Hospital wanted to avoid these sort of troubles for his project and approached InviroTech Systems for a Heat Pipe based solution.
Heat Pipes were proposed for nearly 22 AHUs of the project. The cost of implementing heat pipes for the whole hospital was about 2~4% of the total air conditioning cost. But even after the low costs, the budget did not allow all AHUs to have heat pipes.
Finally it was decided that only the 9 AHUs for 24hours operation will have Heat Pipes.
Those for day-only operation would continue to be conventional system with no specific humidity control. This proved to be a blessing in disguise as now the humidity levels for two types of AHUs, with heat pipes and without heat pipes, could be watched simultaneously and compared.
During Testing and Commissioning, everyone was pleasantly surprised to see that the 9 AHUS with Heat Pipes achieved RH flawlessly, even on a rainy day, whereas those without Heat Pipes had RH all in the range of 65-75% with no load in the building.
