3.6 Electricity allotment and report

3.6.1 Electricity allotment principle

♦ The system allotment adopts peroration and the electricity for peroration is mainly the
electricity consumption of outdoor units and of indoor unit fan and Slave electric heater.
♦ The indoor units of the same refrigeration system share the electricity consumption of the
outdoor sets of the refrigeration system. The indoor units outside the system do not share the
electricity of the outdoor sets of the refrigeration system.
♦ The electric bill of an indoor unit in certain time period can be divided into two parts: basic
electricity and shared electricity.
♦ The basic electricity includes the electricity consumption of the indoor unit due to operations
in Cooling, heating or fan mode. 4-7-1-3-2The shared electricity includes electricity consumed
by outdoor units when all the indoor units are in standby status, as well as the electricity
consumed by outdoor set (an administrator may log onto the system to select to incorporate
this portion of electricity or not) when the whole refrigeration system runs normally but the
billing system has some faults.
- Calculation of basic electricity： Fa = FA*e Where FA is the total shared electricity
consumed by the refrigeration system during a certain time period, and e is the ratio based on
the capacities of indoor units.
- Calculation of shared electricity Fa = FA*e Where FA is the total shared electricity
consumed by the electricity consumers of a system during a certain time period, and e is the
ratio based on the capacities of indoor units.
♦ Electricity fee allotment of a refrigeration system under different circumstances
- When all the indoor units of system are in standby status (not in cooling, heating or fan
mode), each indoor unit shall be allotted with the electricity consumed by the outdoor set during
the time period (shared electricity) in proportion to their capacities.
- Cooling mode (basic electricity)
Indoor unit in Cooling mode：Shared electricity consumed by outdoor set plus electricity
consumed by indoor unit's own fan and Slave electric heater.
Indoor unit in Fan mode： Only the electricity consumed by indoor unit's own fan
Indoor unit in Stand-by：No electricity is incorporated.
- When the system runs in heating mode and there is no indoor unit in conflict status
(basic electricity)
Indoor unit in Heating mode：Shared electricity consumed by outdoor set plus the electricity
consumed by indoor unit's own fan and Slave electric heater.
Indoor unit in Stand-by：No electricity is incorporated.
