EBME Forums Forums Maintenance Technical Assistance Premature room to be constructed

Dear all,

My hospital needs to construct a premature room and its 4x3 metres , i have been asked to design the heating system that will be in place for a totally enclosed room, i think we are talking of temperatures ranging from 30 to 40 degrees celcius.
Any information will be so useful

Thanks

You're the guy with the local knowledge, Roman! What energy sources do you have available?

But don't daytime temperatures approach those figures anyway?

Don't they plan to use incubators etc. then? If not, it's going to be mighty uncomfortable for the staff, I would have thought.

Geoff,


Infact our day/night temperatures for northern Uganda were we shall have this construction range between 30 to 35 degrees Celsius, so are there A.C machines that both heat and cool ? how about humidifiers?

Need more information regarding the requirements.

Roman,
There are some good heat pumps on the market that both heat and cool, I have a friend who does heat management systems for large buildings so asked him about them. You need a 4 port pump. You have two air paths one for internal air and one for external. Then the heat pumps moves the heat from one path to the other depending on if you want the internal air heated of cooled. The huge advantage of these is that the heat pump uses far less power than the heat transfered would need if done by convential means. He says he can run a fair sized office block off a 13amp supply i.e. heating a building with 3kW. Straight heating and cooloing uses a lot of power and you would need two units, one for each.
Have a search for these heat pumps of consult a buildings engineer.

Thanks Rojo for this information, let me do some research on it

One colleague has told me to use a Samsung Air conditioner , this unit can heat and cool at the same time then also mount some humidifiers in the room.

Am afraid wont there be bacteria that will come as a result of mold that comes due to damp conditions? Well i again ask myself that we are still using air conditioners in operating theaters and we expect these places to be free from any bacteria.

Not sure what you asking for? A neonatal unit / special care baby unit? If so these are kept at around 21C for staff and for intensive care use an incubator, for a high dependency unit use a mixture of incubators and heated cots / warming mattresses as needed, for a nursery use a mixture of warming mattresses and normal cots as needed, this is nothing new? If that’s what you were asking? Not sure what all these heating systems are for, sounds like u need air con.

4 x 3 meters, this is very small, is this for a single patient? As Obiwan has mentioned the room should be set at 21C, the air-conditioning should be designed to manage that temperature regardless of the heat generated by all the equipment in the room. You will need to have an exhaust system as well otherwise you will create too much condensation. Split units are not recommended in a healthcare environment.

You will need to get the temperature down for at least two reasons; The staff comfort and for the equipment to be able to work correctly. A incubator will not function correctly in that high an ambient temperature, it will think it has a fault if it is only using minimal heat to maintain the temperature.
