Notes: 
a)  The left and right modes can be switched over on site. The correction coefficient for both 
cooling and heating is 0.9. 
b)  Nominal cooling conditions: (27/19
℃
) indoor dry/wet bulb temperature, (7/12
℃
) entering 
and  leaving  water  temperature.  Nominal  heating  conditions:  20
℃
  indoor  dry  bulb 
temperature, 45
℃
  entering water temperature and 40
℃
  leaving water temperature. 
c)  The noise is tested under the semi-anechoic chamber and the actual value will change 
under different environments.
