3 VV System Overview System Introduction In a Variable ir Volume (VV) system, air delivery volume varies directly with the changing cooling or heating load, thus saving energy at part load conditions. nother benefit that makes VV a popular choice in VC design is its capability to control temperature in multiple zones. Compared to conventional constant volume system, VV system has multiple VV terminal boxes each serving a zone controlling air flow to that zone and maintaining the set-point temperature. Trane leads in VV technology with its innovative range of VariTrane units (Single-duct and Fan-powered types) that are designed for diverse applications and environments. pplications include office space, hospitals, hotels, retail stores, malls and educational facilities. VariTrane provides the most reliable and flexible products available, further enhanced by Trane C controls in implementing systems-level control strategies like ventilation reset and Static Pressure Optimization to improve systems performance and efficiency. VV System Features and enefits VV systems have the following features and benefits: conditioning systems, VV systems can utilize the outdoor fresh air as much as possible during transitional seasons, which not only saves energy consumption, but also improves indoor air quality. It is estimated that over 30% of the annual energy consumption can be saved and 0-30% of total equipment capacity can be reduced by using VV system.. Improved Indoor ir Quality and Comfort ith the integrated C control, VariTrane VV terminal units can keep room temperature and air volume within the pre-set range per actual cooling or heating load requirement and enhance control accuracy of the terminal unit. It allows room temperature to be adjusted per application requirement. Supply air of VV system can be remote and centralized controlled to improve the system efficiency and room air quality. 3. Reliable Operation, Simple Construction VV system is an all-air system. There is no water piping passing through the ceiling of the room, which can avoid problems such as condensation, water leakage and bacteria breeding which may happen in the fan coil system. In addition, VariTrane VV boxes have simple casing construction, which makes installation simple and easy. 4. Flexible System Renovation always occurs in modern buildings. y using flexible duct connection, modification of VariTrane VV terminal unit position can be done according to the room partition and requirement with minimum field modification cost, labor and time. 5. Compatible System VV systems can be integrated with other air conditioning systems to optimize performance efficiency. For example, when integrated with ice storage system, the application of cold air distribution can reduce the initial investment of ice storage system effectively; when integrated with heat pump system it can reduce the initial investment, reducing the noise level by installing several water heat pumps in central location and avoid costly installation of heat pump at each floor. 6. Easy to get integrated with uilding utomation () system VV systems can be integrated to system via C control. System optimization and monitoring of the whole system can be achieved by computerized control. VV System Structure typical VV System consists of:.ir handling units.ir duct system 3.VariTrane VV terminal nuit. Economical Operation VV systems can change the supply air volume according to the cooling and heating load variation to enable the cooling, heating capacity and fan power to meet actual load requirement. Therefore, the system energy consumption can be significantly reduced.

4 VV System Overview System Control Introduction The VariTrane VV box can be connected to Trane s uilding utomation System through two types of control systems. orking station (Optional) ial-up connection or Ethernet/IP connection CU Tracer System In Tracer, the work station using Tracer Summit software monitors the whole system and has many functions such as operating parameter setting, data acquisition, alarming, reports, clock, etc. The uilding control Unit (CU) provides control logic for the whole system and coordinates the operation between equipment level controllers such as MP58 and VV controllers. VV controllers are connected to each other by using RS485, and then connected to CU. The whole control system structure is simple, compatible and designed to accommodate future extension requirements. In addition, using ontalk C controllers, VariTrane VV terminal units can be connected to third party control systems which have ontalk protocol. Tracker system In Tracker, the work station is connected to a Tracker controller. It acquires equipment status, system data information, control command and monitors the system equipment. The Tracker controller provides control logic for the whole system. It coordinates the rooftop equipment (Voyager) & VariTrane VV terminal unit control through the CCP (central control panel). One Tracker controller can be connected to several CCPs, and each CCP is connected to one rooftop unit (Voyager) and several VariTrane VV boxes. Inter communication is possible between CCPs. ll equipment connections in the system are PnP (plug and play), making it convenient for installation and application.

5 VariTrane VV Terminal Unit Overview VV Terminal Unit Classification VV terminal unit controls the air valve opening and regulates the air volume in the room by measuring the temperature difference between room and set point. There are two basic working principles of a VV box: pressure-dependent and pressure-independent. pressure-dependent VV control scheme uses the space temperature sensor to control the position of the modulating device directly. The actual airflow delivered to the space depends on the duct system static pressure at the inlet of the terminal unit. lthough the space temperature sensor will continually correct the position of the modulating device, the response can be sluggish and cause unacceptable temperature variations within the space. In contrast, a pressure-independent VV control scheme controls the actual volume of primary air that flows to the space. n airflow-measuring device on the terminal unit makes it possible. The position of the modulation device is not directly controlled and is basically a by-product of regulating the airflow through the unit. ecause the airflow delivered to the space is directly controlled, it is independent of inlet static pressure. Pressure-independent control increases the stability of airflow control and allows minimum and maximum airflow settings to become actual airflows rather than physical positions of the modulation device. It is clearly most popular in all VV terminal unit controls.

7 VV Terminal Unit Overview Controls Parts and Options UCM4 is a microprocessor-based C controller using pressure-independent control mode to control the supply air volume accurately to make room temperature reach the set condition. In addition, UCM4 also has additional functions, such as optional CO sensor, wireless sensor, to fulfill various customer and application requirements. VV550/55 is a ontalk protocol-based C controller which can provide precise control to VariTrane VV terminal unit. It also has good universality and compatibility, especially in connecting to the third party uilding utomation System with ontalk protocol. ireless sensor eliminates the wiring difficulty at the field and provides more flexibility for layout and sensor positioning. Trane wireless sensor is based on wide spectrum technology, This enhances system security greatly and avoids interference problem when using different system with the same frequency in the same area. UCM4 CO sensor is used to measure CO concentration in the air, converts it into electrical signal and then transmit the signal to the controller which will reset fresh air volume accordingly to ensure indoor air quality and comfort. VV550/55 uxiliary temperature sensor helps VariTrane VV terminal unit changeover between heating and cooling mode automatically without the system controller. Terminal unit controller will compare the temperature differences between the supply air temperature provided by auxiliary temperature sensor and the room temperature provided by zone sensor. It will determine the working mode automatically according to the result without manual adjustment. ireless sensor uxiliary temperature sensor all mounted uct mounted rea sensor Model Zone sensor Occupied / Unoccupied Mode Temperature setting Internal sensor ON CNCE C
