The process of cooling gas at the outdoor unit is as follows: Gas is pumped into the compressor, where the gas will be compressed with high pressure temperature =&gt; Gas passes through the throttle valve to be cooled down to become cold gas.<\/span><\/li>\n<li><span style=\"vertical-align: inherit;\">Gas, after being cooled at the outdoor unit, will be led into the divider and copper pipe system.
