Hi,
In this unit, there are 3 compressors. Can you please explain the sequence of operation also.
One more thing, does the speed of the condenser fans varies with varying discharge pressure (speed control) or remains constant.
Thanks in Advance.
Compressors sequence of operation is on load, on full load all will run, 75% two will run, ......,
Speed of fans is constant but there are three condensers fans therefore on temperature 🌡️ onn-off some time one or some time two,......
Welcome
Plz sir ye bhe batain k hum is ka dx unit k bajay chiller unit ka outdoor unit use karain jis main semi sealed compressor hota ha. Wo use kar sakty hain
Yes can be used
Sir is ka electial connection and kesy working hota ha or thermostat kesy install karain gay
Thermostat is set at unit and temperature remain same
#sir please one video make on hvac compressor part winding cannection.
Ok noted, in future
DX unit waring control ka baro me batayaga please
Ok noted
Why is the bypass line used in these cycles
Mostly used diverting flow.
Sir. I request you. I think sum details are missing just like how much RPM motor are used in blower capacity , pipe size and compressure capacity but the other details is excellent.
Agreed
Tanveer bhai dx volatas 11 tr ki h uske kuchh der chlne k baad coil pr ice aa rha h
Technician will resolve this issue
Give me your WhatsApp no place
If you have meps objective questions and answers send me that video.
No such video
Sir if possible explane bypass line ....still I have confusion
Hot gas bypass (also called discharge bypass) is a feature in a refrigeration system uses to satisfy the mechanical needs of the system during low load conditions. Low load conditions can lead to frosting or freezing the evaporator, refrigerant flood back to the compressor, system shutdown, oil return problems, and several other undesirable conditions
The hot gas bypass utilizes a line from the discharge of the compressor to deliver high temperature, high pressure refrigerant either to the evaporator distributor (preferred) or the suction line to the compressor (which may overheat the compressor).
Man please try to explain shortly,
Ok I will try....one day ....to 20/20
Is unit ko agar flush krna Ho to kaise krenege, kiya process hai
Same like split AC unit
Agar isme solenoid valve laga Ho tb, solenoid valve to tube to band kr ke rakhega na..
You can energise to open through panel
Agar unit baht bada Ho matlab mera trane ka dx unit hai 90 ton ka, iska v process same hi rahega split ki Tarah..
About processor, all brand have some differences. Further to be check
Everything is right par ap boht azafi bolty hen plz ap km ki hi bat kia kary plz
Ok noted your point of view
