4) Circulation amount of refrigerant : An amount of refrigerant to be evaporated in evaporator to obtain the
refrigerating capacity needed. It is expressed in the weight by the unit time.

G: Circulation amount of refrigerant (kg/h)
Q: Refrigerating capacity needed (Kcal/h)
qe: Refrigerating effect by the refrigerant 1kg (Kcal/kg)
To decide the capacity of compressor, the circulation amount of refrigerant should be converted into the suction
gas amount of compressor.

5) Coefficient of performance : The efficiency of refrigerating cycle. It is expressed in COP as the abbreviation
of Coefficient of Performance.
COP
COP
Al : Heat equivalent of work for compression (Kcal/kg)
qe : Refrigerating effect (Kcal/kg)
COP is greater than 1, and the greater COP is, the better the performance is.

Questions and answers
Cual es la conexión de la entrada de corriente de split tcl
The power input connection for the TCL TAC-07CS split air conditioner is as follows:
- For the indoor unit: Connect terminals 1 (WHITE), 2 (BLUE), and 3 (BROWN) to the corresponding terminals on the outdoor unit.
- The power supply connects to terminals L (BROWN) and N (BLUE) on the indoor unit.
- A GREEN/YELLOW wire is used for grounding.
- A 25A circuit breaker or time delay fuse should be installed between the main power source and the unit if a power plug is not used.
