MODEL SELECTION AND CAPACITY CALCULATION 3-1. SELECTION PROCEDURE OF INDOOR UNIT AND OUTDOOR UNIT Please select indoor units and outdoor unit and make the capacity of each indoor unit be larger than cooling and heating load. Confirm the design indoor and outdoor temperature condition Calculate heat load of each room Select indoor unit to match the heat load for each room preliminarily Calculate the estimated capacity of each indoor units (Refer to 3-2)
Page 34
Select outdoor unit to match the total capacity of indoor units preliminarily (Confirm the rated capacity ratio of indoor and outdoor unit, the number of connectable indoor units within limit) Confirm if the capacity of outdoor unit. Calculate the compensated capacity of outdoor unit (Refer to 3-2) ●...
3-2. METHOD OF CAPACITY CALCULATION The capacity calculation method which takes the effects of air temperature, pipe length and frosting/defrosting into consideration is shown below. 1. Calculate the estimated capacity of each indoor unit. (1) Find capacity of indoor unit at rated condition (TCin)r and at design temperature (TCin)d [from 7.

The differences between these two configurations are explained below.
Page 681
ELECTRICAL WIRING Electricity meter connection composition To perform energy saving peak cut control, basically, electricity meters with pulse transmission function measuring all the power consumed by the air conditioner are necessary. Multiple meters installations are also possible as long as the number of electricity meters is within the specified limit.
Page 682
Selection of Electricity meter, CT, and VT Select the electricity meter, CT, and VT by considering the following items. (1) Install electricity meters for each refrigerant system, if circumstances allow. (2) Select VT/CT with a small VT/CT ratio. (3) When using an electricity meter which is specified in pulse units (kWh/pulse), usually select a meter with a 1kWh/pulse output.

INSTALLATION RESTRICTION OF ELECTRICITY METER Functions that requires installation of electricity meter Use an electricity meter having the following functions: ・Electricity charge apportionment function Install for operation using an electricity meter. (Operation without an electricity meter is also possible.) When using an electricity meter, an electricity meter must be installed for all the units which perform apportionment calculation.
Page 686
Installation restriction Install electricity meters in accordance with the following restrictions: (1) Install an electricity meter only to air conditioners which are the target of the function. When electric lights and other OA equipment are connected to the electricity meter, also their power consumptions are calculated.

(10) When performing apportionment calculation using electricity meter The electricity meter shall be connected to the necessary air conditioners which are the target of calculation by the electricity charge apportionment function. When an electricity meter is not connected, electricity charge apportionment calculation using an electricity meter may not be possible.

ELECTRICITY METER SYSTEM Electricity meter system is the connection configuration of one electricity meter and the air conditioner units which are connected to the power line under it. This is set on the System Controller. Set the System Controller to match the actual electricity meter installation configuration. Since the electricity charge apportionment function/energy saving function perform control using the power consumption data from an electricity meter, it is necessary to set an electricity meter system on the System Controller.
Page 693
SETTING OF OUTDOOR UNIT AND SYSTEM CONTROLLER To obtain the appropriate power consumption by System Controller, the power value measured by an electricity meter must be properly conveyed. To do this, appropriate setting at the electricity meter, outdoor unit, and System Controller is necessary. The method of setting the pulse from the electricity meter received by an outdoor unit and the method of setting the pulse value set by system controller are described here.

The following standards may be applicable if local regulations are not available. 1-1. INTRODUCTION This air conditioners use R410A as refrigerant. Though R410A is harmless and incombustible in itself, the room in which the air conditioner is installed should be large enough that the refrigerant gas will not exceed the concentration limit even if the refrigerant gas leaks.
1-2. CHECKING CONCENTRATION LIMIT Check concentration limit following steps , and take appropriate measures depending on the situation. Calculate amount of all replenished refrigerant (kg) per refrigerant system. Amount of replenished Total amount of replenished Amount of additional refrigerant in refrigerant refrigerant per refrigerant replenished refrigerant...
