The division of the ammeters, such as doubleness ammeter、quadruple ammeter etc., are determined
by their endurance capacity to the specific electricity currents. For example the 2.5A doubleness
ammeter means the maximum electricity capacity it can endure is 5A; the maximum electricity
capacity of the quadruple ammeter is 20A. So, the user must ensure the total rating current shall less
than the maximum capacity of the ammeter, and good consideration of the other appliances’ electricity
consumption at home.
⑿The electricity consumption of the air-conditioner: The consumption power, the electricity heating
power and the auxiliary electricity heating power (if applicable) can be identified from the nameplate
of the air-conditioner and can be used for the estimation of the quantity of electricity consumption. For
instance, if the rating refrigerating consumption power is 1200W for one air-conditioner, and 1
kilowatt-hour =1kW/h, then the quantity of electricity consumption of this air-conditioner is
1200W*1h=1.2kW/h=1.2kilowatt-hour. The rating power on the nameplate is validated by the
manufacturer under a certain indoor or outdoor temperature and humidity (Indoor dry bulb 27℃、wet
bulb19℃，outdoor dry bulb 35℃、wet bulb 24℃ ), however, due to the incomplete same condition of
the indoor and outdoor either on the condition of the temperature and humidity or the testing
environment, the consequent actual power consumption may be different from the rating consumption
power. Generally speaking, in terms of refrigeration, the higher environment temperature (the more
atrocious condition) it is, the bigger actual consumption power of the air-conditioner will be. The table
of the below shows the basic parameters of all specific type of air-conditioners:
