    Abstract: The tubular DX evaporator and the air cooling condenser are major components applied in an air source heat pump and an air-cooled chiller. At present, manufacturers do calculations just based on experiences without necessary supports of theoretical calculation. In this article, we give an example of 72kW air cooling condenser, describing the theoretical calculation process of the tubular DX evaporator and the air cooling condenser and also making an analyses based on industrial application.
