4 - 2 Integrated Heating Capacity Correction Factor
3TW30402
NOTES
1. The gure shows that the integrated heating capacity expresses the integrated capacity for a single cycle (from defrost operation to defrost operation) in terms or time.
2. Whe there is an accumulation of snow against the outside surface of the outdoor unit heat exchanger, ther will always be a temporary reduction in capacity, although this will of course vary in
degree in accordance with a number of other factors, such as the outdoor temperature (°CDB), relative huminity (RH) and the amount of frosting which occurs.
INTEGRATED HEATING CAPACITY COEFFICIENT
The heating capacity tables do not take account of the reduction in capacity, when frost has accumulated or while the defrosting operation is
in progress.
The capacity values, which take these factors into account, in other words, the integrated heating capacity values, can be calculated as
follows:
Formula:
Integrated heating capacity = A
Value given in table of capacity characteristics = B
Integrating correction factor for frost accumulation (kW) = C
A = B x C
Correction factor for nding integrated heating capacity.

3TW33622-3
NOTES
1. These gures illustrate the rate of change in capacity of a standard indoor unit system at maximum load (with the thermostat set to maximum) under standard conditions.
Moreover, under partial load conditions there is only a minor deviation from the rate of change in capacity shown in the above gures.
2. With this outdoor unit, evaporating pressure constant control when cooling, and condensing pressure constant control when heating is carried out.
3. Method of calculating cooling/heating capacity (max. capacity for combination with standard indoor unit)
cooling / heating capacity =cooling / heating capacity obtained from performance characteristics table xeach capacity rate of change
In the case lenght of piping differs depending on the indoor unit, maximum capacity of aech unit during simultaneous operation is:
cooling / heating capacity =cooling / heating capacity of each unit xcapacity rate of change for each piping length
<As for RXYSQ4, 5P8V1 - RXYSQ4, 5P8Y1>
4. When overall equivalent pipe length is 90m or more, the diameter of the main gas pipes (outdoor unit-branch sections) must be increased.
[ Diameter of above case ]
Model Gas Liquid
RXYSQ4, 5P8V1
RXYSQ4, 5P8Y1 ø 19.1 Not increased
5. When the main sections of the interunit gas pip diameters are increased the overall equivalent length should be calculated as follows.
Overall equivalent length = Equivalent length to main pipe x 0,5 + Equivalent length after branching
Example: RXYSQ4, 5P8V1
RXYSQ4, 5P8Y1
In the above case (Cooling)
Overall equivalent length = 80m x 0.5 + 40m = 80m
The correction factor in capacity when Hp = 0m is thus approximately 0.78
6. For RXYSQ: use these correction factors in case of vrv indoor unit.

4. When overall equivalent pipe length is 90m or more, the diameter of the main gas pipes (outdoor unit-branch sections) must be increased.
[ Diameter of above case ]
Model Gas Liquid
RXYSQ6P8V1B ø 22.2 Not increased
5. When the main sections of the interunit gas pip diameters are increased the overall equivalent length should be calculated as follows.
Overall equivalent length = Equivalent length to main pipe x 0,5 + Equivalent length after branching
Example: RXYSQ6P8V1B
In the above case (Cooling)
Overall equivalent length = 80m x 0.5 + 40m = 80m
The correction factor in capacity when Hp = 0m is thus approximately 0.86
6. For RXYSQ: use these correction factors in case of VRV indoor unit.

1. All wiring, components and materials to be procured on the site must comply with the applicable local and national codes.
2. Use copper conductors only.
3. As for details, see wiring diagram.
4. Install circuit breaker for safety.
5. All eld wiring and components must be provided by licensed electrician.
6. Unit shall be grounded in compliance with the applicable local and national codes.
7. Wiring shown are general points-of-connection guides only and are not intended for or to include all details for a specic installation.
8. Be sure to install the switch and the fuse to the power line of each equipement.
9. Install the main switch that can interrupt all the power sources in an integrated manner because this system consists of the equipment utilizing the multiple power sources.
