∗In case of selection based on Total Heat Load and Sensible Heat Load, select indoor units which satisfy not only the Total Heat Load but also the Sensible Heat Load of each room. The sensible heat capacity of indoor units is to be corrected for indoor air temperature. If the design temperature of indoor air falls between temperatures listed in table, calculate sensible heat capacity by using the bypass factor calculated by interpolation for each indoor air temperature.

[3] Selection of outdoor unit[3] –1 Define the required total heat load from the indoor units to the outdoor unitDefinetherequiredtotalheatload(A)basedon(1)thesumofthepeakloadofeachroomor(2)thesystempeakload.In this example, select an outdoor unit by (2).Therefore, (A) = 49.8 MBH

46


[3] –2 Provisionally select outdoor unit(1) Calculate CI (Capacity Index) of the selected indoor units. CI of VRV indoor units CI of FXMQ07PBVJU = 7.5 CI of FXMQ12PBVJU = 12 CI of FXMQ15PBVJU = 15

Calculate the total CI of the indoor units. Total CI = 7.5 × 2 + 12 × 2 + 15 × 2 = 69

(2) Provisionally select an outdoor unit based on the total CI of the indoor units The connection ratio of RXTQ-TA shall be between 50% and 130%.

As the total CI of the indoor units is 69, outdoor units 5 ton are connectable.

(3) Confirm that the number of the connected indoor units is within the limitation. The number of the connected indoor units = 6

The max. number of connectable indoor units of 5 ton outdoor unit = 9

47


[3] –3 Calculate the corrected capacity of the outdoor unit.- Calculate the connection ratio of the system. Total CI = 69, CI of RXTQ60TAVJUA = 57 Connection ratio = 69 / 57 = 121%

- Using the capacity table of the outdoor unit, calculate the capacity (B) corrected for outdoor air temperature, indoor air temperature, and connection ratio.

*In case the outdoor air temperature, the indoor air temperature, or the connection ratio falls between temperatures listed in the table, calculate the capacity by interpolation.RXTQ60TAVJUA Cooling Capacity for Standard Condition (Te: 43°F)

Connection ratio 120% 121% 130%

Cooling capacity 62.6 (B) 63.7

(B) = 62.6 + (63.7 – 62.6) × (121 – 120) / (130 – 120) = 62.7

48


-Confirm capacity correction factor by piping length and level difference (K1)

-Calculate capacity correction factor by piping heat loss (K2)(K2) = 1 + (heat loss factor per feet of piping × (equivalent piping length – 25 ft.)) / 100

In cooling mode, heat loss factor per feet at 93°F is calculated as below.(R) Heat loss factor per feet = 0.072*2 + (0.098*1 – 0.072*2) × (93*3 – 86*4) / (95*5 – 86*4) = 0.0922

Using “Equivalent piping length = 100 ft.” and “Heat loss factor per feet = 0.0922”,(K2) = 1 + (0.0922 × (100 – 25)) / 100 = 1.07

-Calculate the corrected capacity of RXTQ60TAVJUA (C) by using (K1) and (K2).Corrected capacity of RXTQ60TAVJUA (C) = (B) × (K1) / (K2) (add defrost correction factor for heating capacity) Therefore (C) = 62.7 × 0.94 / 1.07 = 55.1 MBH

If the corrected capacity (C) is the same or greater than the required total heat load (A), selection is complete.If (C) < (A), return to Procedure [3]–2 and provisionally select a larger outdoor unit.In this example, 55.1 MBH (C) > 49.8 MBH (A), so there is no need to select a larger outdoor unit.

19. Caution for Refrigerant Leaks19.1 Introduction

Points to note in connection with refrigerant leaks

The installer and system specialist shall secure safety against leakage according to local regulations or standards. The following standards may be applicable if local regulations are not available.

The VRV System, like other air conditioning systems, uses R410A as refrigerant. R410A itself is an entirely safe non-toxic, non-combustible refrigerant.Neverthelesscaremustbetakentoensurethatairconditioningfacilitiesareinstalledinaroomwhichissufficientlylarge.Thisassuresthat the maximum concentration level of refrigerant gas is not exceeded, in the unlikely event of major leak in the system and this in accordance to the local applicable regulations and standards.

Maximum concentration levelThe maximum charge of refrigerant and the calculation of the maximum concentration of refrigerant is directly related to the humanly occupied space in to which it could leak.The unit of measurement of the concentration is lb./1000 ft.3 (the weight in Ibs. of the refrigerant gas in 1 ft.3 volume of the occupied space).Compliance to the local applicable regulations and standards for the maximum allowable concentration level is required.

Direction of therefrigerant flow

Room where refrigerant leak has occurred(outflow of all the refrigerant from the system)

Pay special attention to places, such as basements, etc. where refrigerant can stay, since refrigerant is heavier than air.

62


19.2 Procedure for Checking Maximum Concentration

Check the maximum concentration level in accordance with steps 1 to 4 below and take whatever action is necessary to comply.Step1: Calculate the amount of refrigerant (lbs.) charged to each system separately.

Amount of refrigerant in a single unitsystem (amount of refrigerant withwhich the system is charged beforeleaving the factory)

+

Additional charging amount (amountof refrigerant added locally inaccordance with the length or diameterof the refrigerant piping)

= Total amount of refrigerant (lbs.)in the system

Note:Where a single refrigerant facility is divided into 2 entirely independent refrigerant systems then use the amount of refrigerant with which each separate system is charged.

Step 2: Calculate the smallest room volume (ft.3) In case like the following, calculate the volume of (a), (b) as a single room or as the smallest room. (a) Where there are no smaller room divisions.

(b)Wherethereisaroomdivisionbutthereisanopeningbetweentheroomssufficientlylargetopermitafreeflowofairbackandforth.

Opening betweenrooms

Partition

(Where there is an opening without a door or where there are openings above and below the door which are each equivalent in size to 0.15% ormoreofthefloorarea.)

(c) Where there is a gas leak detection alarm device linked to a mechanical ventilator in the smallest room then the next smallest room will become the measurement target.

63


Step 3: Calculating the refrigerant density using the results of the calculations in steps 1 and 2 above.

Total volume of refrigerant in therefrigerant system

≤ Maximum concentration level (lbs./ft.3)Size (ft.3) of the smallest room in whichthere is an indoor unit installed

If the result of the above calculation exceeds the maximum concentration level then make similar calculations for the second then third smallest room and so until the result falls short of the maximum concentration.

Step 4: Dealing with the situations where the result exceeds the maximum concentration level. Where the installation of a facility results in a concentration in excess of the maximum concentration level then it will be necessary to revise

the system. Please consult your Daikin supplier.

1. Air conditioners should not be installed in areas where corrosive gases, such as acid gas or alkaline gas, are produced.2. If the outdoor unit is to be installed close to the sea shore, direct exposure to the sea breeze should be avoided. If you need to install the outdoor unit close to the sea shore, contact your local distributor.
