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.

The connection ratio of RWEQ-TA shall be between 50% and 150%.As the total CI of the indoor units is 234, outside units from 16 ton to 36 ton are connectable.Start from 16 ton which is the smallest outside unit.

22. Caution for Refrigerant Leaks22.1 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.

100


22.2 Procedure for Checking Maximum Concentration

Check the maximum concentration in accordance with steps 1 to 4 below and take whatever action is necessary.

Step1: Calculate the amount of refrigerant (lbs.) charged to each system separately.

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

(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% or moreofthefloorarea.)

(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.

101


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

Total volume of refrigerantin the refrigerant system

≤Maximumconcentrationlevel(lbs./ft.³)Size (ft.³) of the smallest room inwhich there is an indoor unitinstalled

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 on until the result falls short of the concentration level.

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 design.Please consult Daikin supplier.
