Constant Temperature and Humidity Air Conditioning Unit In Clean
Operating Room
Selection of Constant Temperature and Humidity Series for Air
Conditioning in Clean Operating Room
l There are grade requirements for air purification in the space of
the place of use, and the relative temperature and humidity require
control accuracy. The clean operating room air-conditioning
constant temperature and humidity system can be selected; Setting
range: temperature is 18~28℃±1~5℃, relative humidity is
40~70%±3~5%;
l Determine the rated air volume: calculate the circulating air
volume per unit time according to the number of air changes in the
space to be processed and the volume of the space. The rated air
volume of the air conditioning unit in the clean operating room
must be greater than the theoretical calculation air volume
l 
Determine the cold, heat and humidity load: calculate the cold,
heat and humidity load of the space to be handled according to the
relevant indoor and outdoor ambient air parameters, fresh air
volume and surrounding structural forms;
l Determine the model
a. When the rated air volume meets the requirements, but the
cooling and heating load cannot meet the requirements, the
selection should be based on the cooling and heating load.
b. When the rated air volume meets the requirements and the cooling
and heating load also meets the requirements, the selection should
be based on the air volume.
l Determine the condensation method
a. The air-cooled type is suitable for dry and water-deficient
areas. It is convenient to install and widely used. Note that there
should be more than 1.5M space around the outdoor unit.
b. The water-cooled type is suitable for occasions with abundant
water sources, good water quality, and easy installation of the
cooling water system. The cooling water system users should prepare
their own.
l 
Determine the type of air supply structure
a. The front air supply type is suitable for the treatment of
medium and small areas in the same room. The unit has a built-in
high-efficiency and low-noise fan for easy installation
b. The top air supply method is suitable for medium and large
processing spaces. The unit has a built-in high static pressure
centrifugal fan, which can directly handle the air supply.
c. Direct air supply by pipe is suitable for large processing
space. The unit has a built-in fan, and the user needs to provide
an additional air box and return air duct to centrally process the
supply air.
l Special requirements can be customized
a. Computer centralized control or remote monitoring;
b. Special working conditions, overseas power supply voltage
matching;
c. It can provide a constant temperature and humidity clean unit
that exceeds the temperature and humidity requirements of the
normal use environment: low temperature type, high temperature
type, and low humidity type;
d. All fresh air type: meet the temperature and humidity
requirements of all resh air conditions, and run intelligently
throughout the operation;
e. Environment-friendly refrigerant type: green
environment-friendly refrigerants R410A and R134A can be used;
f. Constant temperature and humidity air-conditioning products for
clean operating rooms. Steam heating and humidification are clean
constant temperature and humidity air-conditioning units that can
be heated and humidified by steam;
g. Heat pump heating type: clean constant temperature and humidity
air conditioning products that can be heated by heat pumps
