Medical Refrigeration, Medical Equipment Cooling
Production Description:
The air-cooled low-temperature chiller is a low-temperature
refrigeration equipment that uses air-cooled cooling. It is mainly
composed of compressor, condenser, evaporator, electric control
system, etc., and realizes the purpose of cooling and cooling
through the change of refrigerant in the cycle.
At the same time, the air-cooled low-temperature chiller adopts an
air-cooled cooling method, which dissipates heat to the surrounding
air through a fan, without an additional water circulation system,
saving water resources, reducing water treatment costs, and
improving the cooling efficiency of the equipment .
Production Features:
Glycol chillers have some advantages and disadvantages over other
cooling media. The following is a comparison description:
Advantage:
1. Low temperature range: Glycol chillers can provide lower cooling temperatures, generally
ranging from -20°C to -40°C, or even lower. This makes it useful in
applications requiring cryogenic cooling.
2. Freeze resistance: Ethylene glycol has good antifreeze performance, and its freezing
point is low, which can prevent the cooling system from freezing
and damage in low temperature environment. This makes glycol
chillers suitable for applications in cold climates or low
temperature environments.
3. Thermal conductivity: Ethylene glycol has good thermal conductivity, can effectively
absorb and transfer heat, and provide a stable cooling effect. This
makes glycol chillers excellent in heat control and temperature
stability.
4. Corrosion resistance: Ethylene glycol has good corrosion resistance to many materials
and is compatible with common materials such as stainless steel,
copper, and aluminum. This reduces corrosion problems in contact
with cooling equipment and piping, increasing system durability.
Disadvantages:
1. Higher viscosity: Ethylene glycol has a higher viscosity, and its fluidity may be
slightly worse than other cooling media. This may require more
powerful pumps and piping to ensure good cooling flow.
2. Relatively low heat dissipation capacity: Compared with some other cooling media, ethylene glycol has
slightly lower thermal conductivity. This may require a larger heat
exchanger area or longer cooling time to achieve the same cooling
effect.
3. Higher cost: Compared with some other cooling media, the cost of ethylene
glycol is higher. This needs to consider economic factors when
choosing, and weigh the relationship between its performance and
cost.
Overall, glycol chillers offer significant advantages in cryogenic
cooling applications, but selection requires a combination of
application-specific needs, performance requirements, and
economics.
Working Principle:
Specifically, the working principle of the air-cooled
low-temperature chiller is:
1.The compressor sucks in low-temperature and low-pressure
refrigerant and compresses it into a high-temperature and
high-pressure gas.
2.The high-temperature and high-pressure gas enters the condenser,
releases heat into the air through the radiator, and turns into a
high-temperature and high-pressure liquid.
3.The high-temperature and high-pressure liquid enters the
evaporator, exchanges heat with the outside through the evaporator,
and turns into low-temperature and low-pressure steam.
4.The low-temperature and low-pressure steam enters the compressor
again, and the cycle repeats.
