3 About us We established Renovo Zhuhai Ltd. at the end of 2007, which specializes at the research & development, design and manufacture of precision air conditioning Renovo Zhuhai Ltd. is the research partnership of China Mobile. Many of field giants have been following China Mobile s study results. We have approved by ISO9001, ISO14001 and GB/T Renovo s emphasis on products quality and environmental sustainability has paved the way for CCC certification, CE certification, UL certification for some models, lots of patents and energy efficient products.

4 History At the same year 2007, start to make coils 2008 we signed a joint research agreement with Shanghai Jiao Tong University Coil Then, start to manufacture the precision air conditioner Precision Air conditioner

5 Our Strategy Simplicity Efficiency because simplicity Speedy Fast Customer response Fast and accurate delivery Servicing Provide our customer with 24-hours around the clock service Everything is for the customer and market need

11 Cooling capacity Cooling capacity 6KW~125KW

12 Air-cooled DX units Cooling capacity: 6.0~120kw Two types of evaporator configuration: P type and V type Humidifying Range:3~8 kg/h Heating Range: 2~24 kw (optional up to 27kw) Air cycle Range:1800~30000 m3/h R22 refrigerant is standard. R407c and R410a refrigerant are optional Down flow and up flow air supply Our air-cooled direct expansion units take the heat from indoor and transfer it into outside by using condenser. The indoor unit and condenser would become a closed circuit after completed installation. It fits for the areas where lack of water or cooling water system P type V type

13 Chilled water units Cooling capacity:8~125kw Two types of evaporator configuration: P type and V type Humidifying Range:3~30 kg/h Heating Range: 2~40 kw Air cycle Range:1580~42000 m3/h Down flow and up flow air supply Water coming generally from a chiller is used in these units to transfer the heat. The flow of liquid through the unit water coil is controlled through an internal 2 or 3-way valve. The unit is normally used in the place where owns chilled water system

23 Integrated solution for data center Micro modular Data center in a box

24 Integrated solution for data center 10KW split type 5KW mono block type

25 Air-cooled screw free-cooling chiller IT technology grows fast, and the data center has become an inevitable product due to data central tendency. As a large number of new rack server and blade server had been used in the data center, and the thermal density reached 30-40KW per cabinet, so common air-conditioning system has been unable to meet the cooling requirements of high-density heat dissipation room. Now the data center needs a new type of efficient, energy-saving, manageable computer room solutions urgently, that s why Our s RFAW free-cooling screw chiller emerged. Cooling capacity 200~1500KW Efficient semi-enclosed enclosed twin-screw compressor the EER> 4.8 Classification of compressor control 25%, 50%, 75%, 100% variable load operation International advanced cooling power distribution components: ABB, Schneider, Danfoss Advanced natural cooling techniques Wide range of ambient temperature -15 ~48 R22 R134a R407c refrigerant is optional

26 Air-cooled screw free-cooling chiller Summer or hot weather: Chiller unit start-up and its compressor operated for cooling mainly Transitional season of spring and autumn or cool weather: When the ambient temperature is lower two degrees Celsius or above than the temperature of the returned chilled water (the temperature difference can be manually adjusted, but not recommended lower than two degrees Celsius), open three-way valve in the system, and then the system automatically turns on free- cooling refrigeration. Once the free-cooling can not meet the requirement, compressor refrigeration will be turned on for supplement Refrigeration theory Winter or cold weather: e with the decrease ease of the 1.Compressor 2.condenser ambient temperature or the indoor heat load 3.nature cooling heat exchange reduction, free-cooling system gradually increases coil 4.EXV 5.3-way adjustable the proportion of its refrigeration until completely valve 6.shell-and-tube evaporator using free-cooling, and then we can stop the compressor refrigeration
