2.2 Application Notes
This product is intended for use in industrial equipment applications that utilize a 230V AC
power supply. The purpose of its installation is to control cabinet temperature between 20
to 45
℃
; keeping within this range will ensure that all thermal sensors operate as intended.
Safety and Use Instructions:
o
Transport the unit in an upright position
o
Do not store in a high temperature, high humidity environment (<70
℃
, <95%).
o
If the unit will not be in use for a long period, disconnect the main supply power
2.3 Working Principles
•
The Air Conditioner uses a standard vapor compression cycle
o
The main parts of the cooling system include: compressor, condenser, expansion valve, evaporator,
internal fan, and external fan
•
Principle of refrigeration: The compressor compresses warm, low-pressure vapor into hot, high-pressure vapor.
This hot high-pressure vapor travels through a condenser where it dissipates heat to the environment. The high-
pressure condensate then flows through an expansion valve which reduces the fluid’s pressure and partially
vaporizes the fluid. The expansion and partial vaporization cool the fluid (liquid and vapor mixture), which
allows the remaining liquid to vaporize and cool the air flowing through the evaporator.
•
The air internal to the cabinet is circulated through the evaporator to be cooled to the desired temperature
•
Air outside of the cabinet flows through the condenser and is used to condense the hot vapor in the
refrigeration cycle.
•
Air outside of the cabinet never mixes with the air internal to the cabinet
