1 Scope
This standard specifies the terminologies and definitions of the main performance parameters, test requirements, test methods, test deviation, gross electric power and evaluation on coefficient of performance for the motor driven water chilling (heat pump) packages using the vapor compression cycle.
This standard is applicable to the performance test for motor driven water chilling (heat pump) packages using the vapor compression cycle (hereafter referred to as "packages"). Cooling tower all-in-one packages, brine packages and ethanediol packages may also refer to the provisions of this standard.

3 Terminologies and Definitions
For the purpose of this document, the terminologies and definitions specified in GB/T 5773-2004, GB/T 18430.1, GB/T 18430.2 and JB/T 7249 as well as the following ones apply.
3.1
Gross electric power
The sum of input power consumed during package operation under the specified cooling (heating) performance test conditions.
Note 1: gross electric power includes the input power of compressor motor, oil pump motor, electric heater and operation control circuit, etc.
Note 2: as for air-cooling packages, the gross electric power also includes the power of cooling fan; as for evaporative-cooling packages, it also includes the pump power of water sprayer and the power of cooling fan.
