19 System description I n t r o d u c t i o n Traditional DC INVERTER series NEW Series DC INVERTER ES New series DC INVERTER ES HITACHI presents the new DC INVERTER ES range, which replaces the H(V)RNE series. The IVX series uses Inverter technology which allows the set temperature to be reached while optimizing electricity consumption and bringing down CO 2 emissions. With the same quality and design parameters, HITACHI has developed units that are more compact and lighter than the previous models. This series is compatible with HITACHI's SYSTEM FREE system, eliminating the need to duplicate indoor unit models and thus reducing the need for stock. For this new IVX series the new HLINK II communication protocol has been developed. This allows up to 160 indoor units and 64 outdoor units to be connected for a same HLINK II installation, and is compatible with the rest of the HITACHI range. True to its commitment to the environment, HITACHI has designed the new IVX series in compliance with all applicable European directives and regulations (WEEE, RoHS,Green Dot, FGas,...) and has opted to use the R410A refrigerant which does not damage the ozone layer (ODP=0).

48 Features and benefits of DC INVERTER ES Main features of the units: Highly efficient scroll compressor exclusive to Hitachi Compact design The new HITACHI DC INVERTER scroll compressor has been developed to increase efficiency, reliability and power consumption. High pressure shell It acts as an oil separator reducing the amount of oil circulating in the cooling system giving better heat exchanger efficiency. Motor heat is not added to the suction gas before compression, which reduces the discharge gas temperature. This is particularly important at low suction temperatures. The discharge gas cools the motor sufficiently. Coolant cannot enter the shell during the off cycle causing oil dilution and oil foaming at start up. New system of regulating pressure (only for RAS4~6HVRNSE), increasing the compressor's efficiency and reliability in part load mode. This system ensures the work pressure of the compressor is always at optimum level regardless of the charge, so that the ratio between the discharge pressure (Pd) and the suction pressure (Ps) is optimum as in the following graphic: Overcompression zone based on the new pressure regulation system Pd Pressure Ps Volume Lubrication Bearing in mind that lubrication is one of the most important factors in the service life of a compressor, HITACHI has developed a system based on the pressure differences between the suction and discharge using a secondary pump at the base of the compressor. As a result, all of the compressor's moving parts are lubricated evenly, ensuring high reliability in terms of its operating range, even at low frequencies. Protection against liquid return When the compressor is at rest, the moving scroll rests on the casing. When the compressor starts to run, the pressure in the chamber under the scroll builds up through two bleed holes in the medium pressure section of the compression stroke. This pressure then forces the scroll up against the housing and seals the compression chamber. If liquid returns to the compressor, the resulting increase in pressure forces the scroll downwards, breaking the seal and allowing the liquid to pass back into the compressor body, where it will boil off due to the higher temperature. pag. 48 TCGB0052 rev 0 06/2008

(rpm) New threeblade fan with lower body PWM (pulse width modulation) concept of speed control The switching element (a power MOSFET) switches back and forth at a frequency of several tens of khz. This controls the ON/OFF duty rate per cycle and changes the voltage applied to the fan motor to control the rotation speed. New fan propeller Hitachi uses high technology to achieve the lowest noise. The new fan has three blades instead of four. It is designed to have a lower body than traditional fans, and achieves surprising results, with a noise reduction of up to 4dB (A). Large range of operating possibilities The use of these machines together with CSNET WEB can increase the performance of these installations even more by: CSNETWEB Ability to lock functions from the central control Scheduled programming, which prevents these machines from running continuously in rooms which are not being used, and allows rooms to be preheated or prerefrigerated just before being occupied. Limiting the set temperatures, which means that machines do not work at maximum capacity when comfort does not require it. Locking functions from the central control, thus avoiding incorrect or ineffective use of the units. All these and many more functions mean that the use of the installation as a whole can be optimized. And it is worth remembering that because of the wide range of indoor units you can always find the unit with the power and type of installation that best suits your needs. pag. 51 TCGB0052 rev 0 06/2008

The Econofresh kit can provide up to 100% fresh air and has the ability to provide free cooling through the damper when the outdoor temperature is below the indoor set temperature. This system will not only maintain the correct room temperature and provide fresh air, but also natural cooling. It therefore increases energy savings. 1 Return air duct RPI unit Econofresh kit NOTE: If the outdoor air temperature is lower than 3 ºC, the fresh outdoor air rate will decrease. Damper airflow control provides comfortable cooling. A microcomputer controls the angle of the damper according to both room air temperature and outdoor temperature to adjust the fresh air flow, thus keeping the room temperature constant. Operation mode Fresh air duct Fresh air cooling during intermediate seasons saves energy. This unit uses an economizer for cooling, which takes in fresh air if the outdoor temperature is cooler than the indoor air, as shown in the graph below. In this situation, no compressor is used and thus a remarkable amount of energy is saved. Graph example of cold region temperature: Time (h) / year The compressor stops during cooling 0 operation Outdoor temp (ºC) The power consumption is reduced by more than 20% during operating mode with cooling by using the Econofresh + kit RPI5.0FSN2E.

102 Capacities and selection data 4.1. Selection procedure for the UTOPIA DC INVERTER ES system The following procedure is an example of how to select the system units and indicates how to use all the parameters indicated in this chapter Selecting unit features Considering the layout of the building, the possible position of the indoor units and the air flow distribution, select the unit features that provide the greatest efficiency and comfort. Decide on a position for the outdoor unit that facilitates service and maintenance tasks, as well as easy installation of the refrigeration pipes. Use the information provided in the following sections: For general information: Chapter 2. For correction factors: Section 4.7. For operating space options: Chapter 3. For unit combinations: Section 4.4. For air flow distribution: Section 4.10 Temperature distribution diagrams. For noise characteristics: Section 4.11 Sound data. For determining the position of outdoor units: Section 4.12 Outdoor unit. Piping length and lift range: Chapter 7.? NOTE: The maximum indoor unit capacity combined with the capacity of the outdoor unit should be carefully considered to ensure the correct distribution of the indoor units in each building. Step 1: If a duct type unit is selected, the fan performance for duct calculation should be considered, as indicated in Section 4.9. The units are designed with three possible static pressure ranges in order to adapt to all installation requirements. The UTOPIA DC INVERTER ES system allows installation of up to 3 independentlycontrolled indoor units Selection guide for UTOPIA DC INVERTER ES The following example shows how to select indoor and outdoor units in the UTOPIA DC INVERTER ES system. System requirements Calculate the cooling and heating capacities of each indoor unit according to its operating conditions: Total load required for each room Room Item Total Estimated cooling load kw 4,00 3,90 4,10 12,00 Estimated heating load kw 3,81 4,00 3,90 11,71 pag. 102 TCGB0052 rev.0 06/2008

106 Capacities and selection data Step 4: Sensible heat capacity (SHC) System requirements specify a sensible heat load of 8 kw. When unit performance capacity is defined, it is possible to calculate sensible heat capacity for each indoor unit. Obtain the sensible heat factor (SHF) in Section 4.10 for high fan speed. Calculate the corrected sensible heat factor for all indoor units using the formula: SHC = unit performance capacity x SHF SHC RPI2.0 = 4.43 x 0.76 = 3.37 kw SHC RPI2.0 = 4.43 x 0.78 = 3.46 kw SHC RPC2.0 = 4.43 x 0.72 = 3.19 kw The capacity data consider a relative humidity of 50%. Therefore the 17 C WB temperature condition of the air inlet has a DB temperature of 24 C. As a result of the difference between the indoor air inlet dry bulb temperature required by the system (25 C) and the indoor air inlet dry bulb temperature recorded in the cooling capacity data (24º), the corrected sensitive heat must be adjusted for each indoor unit.

108 Capacities and selection data 4.2. KPI system selection procedure Selection guide for KPI There are two methods for calculating the suitable unit: Method 1, Areas Method 2, Inhabitants It is important to check the local legislation regarding certification of the final results. This is a quick method for calculating the ventilation. Remember that this result is only approximate. The air will need to be renewed in order to reduce the CO 2 levels in the room and to eliminate unpleasant odors, smoke, and pollution. In short, the room must be ventilated to provide a greater comfort level for the occupants. The first point to analyze is the type of activity for which the room is used. An office is not the same as a bar. Then, the volume of the room must be calculated. Method 1: This method is based on areas and the frequency of air renewal. Volume V (m³) = A x B x C A x B = Area of room (m²) C = Ceiling height (m) See table below to determine the number of air ventilations per hour required depending on the type of room. This table is not standard for all countries, although the layout will be the same. Consult the specific standards for each country.

The airflow is therefore: C= 180 x 4 = 720 m³/h The correct KPI model for this installation is KPI802E1E. It provides an air flow of between 680 and 800 m³/h. pag. 108 TCGB0052 rev.0 06/2008

The Econofresh kit is able to reduce this consumption. Using this system it is possible to intake fresh air using the indoor unit when the thermostat is off. Depending on the outlet and inlet temperature, the Econofresh kit works as an intelligent system, enabling the airflow to be controlled at all times by modifying the position of the damper. The Econofresh kit makes it possible to work with the CO 2 or enthalpic sensors in order to control the quality of the air inside the room. The following procedure explains the method for calculating the Econofresh kit and its advantages in a natural cooling system. First, the pressure loss in the ducts of this installation must be factored in. This loss varies from one installation to another. (For more information See the "Pressure Loss data" chart). These pressure loss charts must be included in the RPI chart. High static pressure produces a performance curve with an air flow rate for 0% (B) of fresh air and 100% (A) of fresh air (natural cooling system). (For more information, see the "Air flow calculation" chart).

113 Capacities and selection data Free cooling mode (Economizer) Determining the maximum heat capacity (free cooling). Calculate the capacity by entering the maximum outdoor air flow (V Omax ), the room temperature (T i ) and the outdoor unit temperature (T o ) in the following formula. Q SHmax = V Omax x (1ß) x (T i T o ) x 0.02 β = 0.2 bypass factor for RPI 5.0 HP V omax = 25 m³/min T i = 25 C T o = 15 C Q SHmax = 4.00 kw This is the maximum capacity allowed by the Econofresh kit in these conditions to reduce the power supply each hour. AllFresh mode The new EconoFresh Kit can also work with the "AllFresh mode". In order to configure this mode, you must use the additional E 1 function, by configuring it with the remote control. AllFresh mode allows Econofresh to supply only outdoor fresh air. It is able to do so because the damper is fully open during this operation mode, while the indoor unit is working. If AllFresh mode is used constantly, the air flow rate will decrease. It is therefore necessary to calculate the cooling capacity by using the minimum air flow rate (point A). This operation mode is extremely useful for buildings with a high density of occupants such as public buildings. 4 pag. 113 TCGB0052 rev.0 06/2008
