When Daikin launched the VRV air conditioning system in 1982, it introduced the world’s first use of variable refrigerant flow control. Table of contents Installer and user reference guide 3 RXMLQ8 + RXYLQ10~14T7Y1B* VRV IV system air conditioner 4P543427-1A – 2020.10 11.2.5Symptom: The … About VRV. • When installing or relocating the system, keep the refrigerant circuit free from substances other than the specified refrigerant (R410A) such as air. 1. calculation of additional refrigerant charging amount 4. 4.All the precharged gas is for the outdoor heat exchanger not for the additional feild pipe added by the engineers. Monitor VRV system using Daikin's built-in state-of-the-art methodology. Calculating the additional refrigerant charge Parameter [D] Indoor unit FXMQ type NOTE capacity The refrigerant charge of the system must be less than 210 lbs. The refrigerant charge of the system must be less than 100 kg. 5.While still in vaccum with the right calculations charge the gas and you should not have any worries. Depending on the amount of charge you may have to put it in additional charge mode. So you can enjoy complete confidence from tender to installation of a VRV system, while ensuring your … In times where the VRV market is growing fast, this enables us to do our business in a sustainable way, while securing future growth. Any presence of air or other foreign sub-stance in the refrigerant circuit could result in abnormal pres-sure rise or rupture, resulting in injury. Daikin’s Commission With Confidence service includes the supply of R410A refrigerant trim charge is guaranteed as part of a commissioning package for a set fee. Page 30: Calculating The Additional Refrigerant Charge 14 .2 . Brian8383. Display system ef­ficiency on visual charts and graphs. This means that in case the calculated total refrigerant Refrigerant charge is equal to or more than 209 lbs. 06-09-2018, 09:07 PM #3. This technology circulates only the minimum amount of refrigerant needed at any one time and enables individual climate control of air conditioning zones. The RXYQ-P7 units can be combined with Daikin VRV indoor units for air conditioning purposes, and suitable for R410A. Pipe size from the top of my head: 1/4 - 0.0025 g 3/8 - 0.012 g 1/2 - 0,056 g.....(check your booklet supplied by DAIKIN) type (100 kg). 2. record of additional refrigerant charge amount and result of leak check operation request for the indication of additional refrigerant charging and leak detection operation result be sure to fill out the blanks, which are needed for after-sale services.
