Introduction Si30-813 1. Introduction 1.1 Safety Cautions Cautions and Warnings Be sure to read the following safety cautions before conducting repair work. Warning” and “ Caution”. The “ The caution items are classified into “ Warning” items are especially important since they can lead to death or serious injury if they are not followed closely. The “ Caution” items can also lead to serious accidents under some conditions if they are not followed.
Si30-813 Introduction Caution Do not repair the electrical components with wet hands. Working on the equipment with wet hands can cause an electrical shock. Do not clean the air conditioner by splashing water. Washing the unit with water can cause an electrical shock. Be sure to provide the grounding when repairing the equipment in a humid or wet place, to avoid electrical shocks. Be sure to turn off the power switch and unplug the power cable when cleaning the equipment.
Introduction Si30-813 Warning Be sure to use the specified cable to connect between the indoor and outdoor units. Make the connections securely and route the cable properly so that there is no force pulling the cable at the connection terminals. Improper connections can cause excessive heat generation or fire. When connecting the cable between the indoor and outside units, make sure that the terminal cover does not lift off or dismount because of the cable.
Si30-813 Introduction Caution Check to see if the parts and wires are mounted and connected properly, and if the connections at the soldered or crimped terminals are secure. Improper installation and connections can cause excessive heat generation, fire or an electrical shock. If the installation platform or frame has corroded, replace it. Corroded installation platform or frame can cause the unit to fall, resulting in injury. Check the grounding, and repair it if the equipment is not properly grounded.
Introduction 1.2 Si30-813 PREFACE Thank you for your continued patronage of Daikin products. This is the new service manual for Daikin's water cooled VRV System. Daikin offers a wide range of models to respond to building and office air conditioning needs. We are confident that customers will be able to find the models that best suit their needs. This service manual contains information regarding the servicing of water cooled VRV System.

Features Si30-813 1. Features A water cooled intelligent individual air conditioning system suitable for tall multi-storeyed build ings. This unique system can perform as heat pump or heat recovery to any suitable application. What is water cooled VRV III? Water cooled VRV III is an individual air conditioning system that utilises water as a heat source.
Si30-813 Features Cooling tower Boiler (for heating) Water piping To Cooling tower (Closed type), Boiler Refrigerant piping To Indoor units General Information 3
Features 1.1 Si30-813 Design Flexibility Enhanced design flexibility and cold climate capability Water cooled VRV III uses water as its heat source, so it is optimal for large buildings, including tall, multi-storey buildings, because the system can tolerate water pressure of up to 1.96 MPa. Furthermore, if the currently installed heat source’s water temperature is between 10˚C and 45˚C, it may be possible to use the existing water pipe work and heat source.
Si30-813 Features Long refrigerant piping length Within the refrigerant piping system, a maximum of 120 m of actual piping length and 50 m*2 of level difference between the VRV-WIII and indoor units are possible. Water piping does not enter occupied spaces, so there is no worry of water leaking. Multiple use k q Max. 120 m First indoor branch Max. 140 m Max. 300 m a p f b First outside branch Single use *The rest of indoor units are the same as for single use.
Features 1.2 Si30-813 Easy Installation Compact and lightweight Adoption of a water heat exchanger and optimisation of the refrigerant control circuit has resulted compact and lightweight equipment. A weight of 149 kg and height of 1,000 mm make installation possible in buildings with limited space, or where no space is available for outdoor units. This makes the system ideal for places that have no area outside—such as underground malls.
Si30-813 1.3 Features Energy Saving Heat recovery Daikin offers 2-stage heat recovery operation. The first stage of heat recovery operation is within the refrigerant system. By controlling the BS unit that switches cooling and heating, simultaneous cooling and heating operation is made possible, with heat recovery performed between indoor units. The second stage of heat recovery operation is within the water loop, where heat recovery is performed between the VRV-WIII units.
Features 1.4 Si30-813 Enhanced Usability A variety of functions that realise easy installation and improve reliability • Features a pump interlock function that controls the pump of the heat source simultaneously with the starting of the VRV-WIII unit. This significantly simplifies operation and management. • Employs DIII-NET to enable the shared use of the wiring between the indoor units, the VRV-WIII unit and the central control wiring.
Si30-813 Features New BS unit for heat recovery can improve comfortability by switching between cooling and heating operation independently. Originally, switching was performed by indoor units, which lowers the operation capacities of other indoor units. Now the switching can be conducted on this new BS unit, successfully reducing the effects to other indoor units when compared to the VRV-WII system.

Precautions for New Refrigerant (R-410A) Si30-813 1. Precautions for New Refrigerant (R-410A) 1.1 Outline 1.1.1 About Refrigerant R-410A Characteristics of new refrigerant, R-410A 1. Performance Almost the same performance as R-22 and R-407C 2. Pressure Working pressure is approx. 1.4 times more than R-22 and R-407C. 3. Refrigerant composition Few problems in composition control, since it is a Quasi-azeotropic mixture refrigerant.
Si30-813 Precautions for New Refrigerant (R-410A) Thermodynamic characteristic of R-410A Temperature ( ) Steam pressure (kPa) Liquid Vapor Precautions for New Refrigerant (R-410A) Density (kg/m3 ) Liquid Vapor Specific heat at constant pressure (kJ/kgK) Liquid Vapor Specific enthalpy (kJ/kg) Liquid Vapor Specific entropy (kJ/KgK) Liquid Vapor 317
Precautions for New Refrigerant (R-410A) 1.2 Si30-813 Refrigerant Cylinders Cylinder specifications • The cylinder is painted refrigerant color (pink). • The cylinder valve is equipped with a siphon tube. Siphon tube Cylinder Refrigerant can be charged in liquid state with cylinder in upright position. Caution: Do not lay cylinder on its side during charging, since it cause refrigerant in gas state to enter the system.
Si30-813 1.3 Precautions for New Refrigerant (R-410A) Service Tools R-410A is used under higher working pressure, compared to previous refrigerants (R-22, R-407C). Furthermore, the refrigerating machine oil has been changed from Suniso oil to Ether oil, and if oil mixing is occurred, sludge results in the refrigerants and causes other problems. Therefore, gauge manifolds and charge hoses that are used with a previous refrigerant (R-22, R-407C) can not be used for products that use new refrigerants.

Precautions for New Refrigerant (R-410A) Si30-813 4. Leak tester Specifications • Hydrogen detecting type, etc. • Applicable refrigerants R-410A, R-407C, R-404A, R-507A, R-134a, etc. Differences • Previous testers detected chlorine. Since HFCs do not contain chlorine, new tester detects hydrogen. 5. Refrigerant oil (Air compal) Specifications • Contains synthetic oil, therefore it can be used for piping work of every refrigerant cycle.
Si30-813 Precautions for New Refrigerant (R-410A) • Temperature scale indicates the relationship between pressure and temperature in gas saturated state. Differences • Change in pressure • Change in service port diameter 7. Charge hose for R-410A (Hose with ball valve) • • • Specifications Working pressure 5.08 MPa (51.8 kg/cm2) Rupture pressure 25.4 MPa (259 kg/cm2) Available with and without hand-operate valve that prevents refrigerant from outflow.
