    Bed Cooler for Hospitals

    You can still modify it anytime you want. Make sure you place the box in ventilated area and the box will need to reject the heat.. set the temperature to 25C first, then adjust to suit..too cold will not be comfortable although one will get the cooling sensation initially. Good to ask how...

    Ask around for the construction material. Almost all commercial bed coolers are made of electronic chiller. they are small and compact. Most electronic chiller use aluminum heat sinks which is acceptable so long if they dun use aluminum for water circuit as they may corrode easily over time...

    Bed Cooler for Hospitals

    The differences between air conditioned and natural ventilated ward is more than double. It was quoted that the natural ventilated wards (B2 and C) are subsidized.. think the subsidy is limited. It is the room sharing of space and cost of airconditioning that make up the differences...

    Bed Cooler for Hospitals

    I am viewing from hygienic views.. if it is to just get rid of the smog, a ventilated system consisted of just fans and ducting with a good filter works much better than portable air conditioners. If it is for comfort; of course, portable air cond wins hands down but it is just unhygienic to...

    Bed Cooler for Hospitals

    Hope this is a temporary. It is not a wise decision. 1st, the portable airconditioners are not as efficient; 2nd, one has to share the conditioned air. I would not be able to sleep well if I know someone in the same ward keep coughing or have some yet to be detected commutable disease...

    Engine Stop-start

    This feature will save petrol if one has a lot of city drivings. when there is a mixture of city and motorway driving, the savings would be reduced. One thing for sure, the car must be maintained in top condition; i.e. when there is a demand to start the car, the car must start. In the...
