air-conditioner. Although the unit “W” is same as the one used for the cooling capacity, they have
different practice signification: As we all know 1Hp=735.499W, which stands for the consumption
power of the compressor, but the cooling capacity indicates the quantity of heat absorbed from the
room by air-conditioner within a unit time. So, somebody may ask: is this against the energy
conversation law? The answer is: we shall consider about the energy conversation law in a total
air-conditioning system: e.g. the power consumption of the compressor (+other power consumption by
fan and motor etc.) + the quantity of heat (e.g. the cooling capacity) absorbed from the room=the
ejecting quantity of heat by the (Outdoor part) air-conditioner.
The general units’ conversion is as follows:
1Hp (or 1 Horse Power) =735.499W the abbreviation is 735W (British unit Horse Power=745.7W)
1W=0.86kcal/h(Kcal. or Therm)
1kcal/h=3.9683Btu in abbreviation of 4Btu
1W=3.412Btu/h
1cooling ton=13878kJ/h=3330kcal/h=3873W (US cooling ton and Japanese cooling ton)
t Celsius degree (℃)=T absolute temperature (K)-273.16
t Fahrenheit (℉)=9/5t+32(℉)
1Pa=1.02*10-5kgf/cm²
⒁The noise of air-conditioner:
It’s not allowed to have the strange noise and vibration when the air-conditioner is running. The
regulations with regard to this issue are specified as following:
①The error is permitted by the manufacturer if +3dB(A) in difference with the announced figure (by
nameplate, manual or adv. Etc.) of the air-conditioner’s noise.
②T1、T2 model air-conditioner shall be tested in the Semi-anechoic Room, There are 2dB(A) can be
added to T3, Sound Pressure Level.
③The noise value obtained from the anechoic room must be noted by the letters of “Tested in the
overall noise eliminated room”.
④The difference between the noise level + interference and the rating noise value shall not less than
10dB (A) when the noise test ongoing.
⑤The ground shall be the reflection surface when there is semi-noise eliminated, and the noise space
is consisting of 2 indoor and outdoor rooms.
⑥The measurement to the noise shall be undertaken 30 minutes later after the air-conditioner running
normally and when the ambiance temperature reach ±1.5℃ of the rating working status.
⑦The measurement shall be undertaken at the point of 1meter height and 1 meter far away to the
front panel of the air-conditioner.
