COP 3.4???

it seems that heat pump e-compressors can provide sufficient heating capacity, because they are featured by two-stage vapor compression and air source heat pump technology. In a -10℃ ambient...

It seems that heat pump has a higher efficiency than PTC heater. If a heat pump system is applied on EVs, how does it absort heat from the ambient to provide warm air to the cabin at -20℃ or lower...

It seems that there are more and more EV manufacturers choosing heat pump HVAC system for efficient heating in cold winter days. Telsa has cooperated with a China-based compressor manufacturer with...

Does an inverter type electric vehicle air conditioner compressor run in AC current or DC current?

How to adjust Danfoss KVL15?

yes, you are totally right. To write an article relating to inverter type scroll compressor, I have searched tons of information online. Some information from the website of main compressor...

hi, I just learnt that high volt compressors can be driven by DC320V, DC350V, DC380V, usually for EV AIR CONDITIONING SYSTEM.

Why different HVAC system is used in the driven cabin and passenger compartment in an electric bus? in an air-conditioned electric bus, the cooling of the driver cabin is separate from the passenger...

I am planning to write an article with topic relating to "electric AC compressor" to update my website. I know that the high-volt compressors are usually used in large EVs, like pure electric city...

I have searched online and found a picture. it shows that the CPR valve is installed in the evaporator.

so where is it installed in a refrigeration system? in the evaporator?

nope, i mean what do u think of spare parts made by Chinese factories.

Crankcase pressure regulator

Does the air conditioning system have a CPR valve? I know CPR valve is an option in refrigeration system, but have no idea whether it is necessary in vehicle A/C or home used A/C system.

What about parts made by Chinese factories?

Working in a company specialized in refrigeration system manufacturing, I think Carrier is a benchmarking enterprise, unsurpassable.

Actually it's a marketing article. I have no idea whether it's proper to post the link here or not. But if u would like to read, I am glad to post my article link here: Refrigerated Vehicles Playing...

Thank you so much. it helps me a lot.:cheers:

Thanks, I will:angel:

because I am trying to write an article on the usage of refrigerated trucks, especially its importance in the carriage of biomedical waste. When I google such information, there is little to no...

would like to know how hospitals manage the biomedical/clinical waste, but I cannot even find one useful link with detailed explanation. Also wanna know more information on refrigerated truck...
