Cooled module unit Description: air-cooled module units into a single type of cold and heat pump, air-cooled heat pump module unit which sets cooling and heating functions in one, can be cooling, but also heating and summer cooling can be achieved, winter heating, a multi-purpose machine. Therefore, air-cooled heat pump heating boilers are usually neither, nor heating network or other reliable source, but requires annual air conditioning HVAC engineering design of the preferred scheme, the unit can be used with fan coil or cabinet, ceiling mounted air handling and air units together to form a new semi-centralized air-conditioning system, fan coil system has many advantages, flexible layout, appearance, architectural space saving, easy to adjust, you can stop alone, without open affect the other room, and low operating noise. Conserve water cooled module unit eliminates the need for cooling water systems are essential cooling towers, pumps, boilers and piping systems, and many other appropriate accessories, the system is simple, save installation space, easy maintenance, management and because they save energy, avoid condenser water quality too poor areas caused by fouling, clogging pipes and other phenomena, while also saving water resources. Saving energy than water-cooled module unit time investment unit to be slightly higher, but lower than the annual operating costs of water-cooled chillers, computer room construction costs at least in a variety of cold and heat source system, the maintenance cost is about water cooling style or half the cost of the boiler. Is cold (hot) water conditioning equipment products in maintenance, repair the most economical and simple models. The unit can be placed directly on the roof, on the podium or platform level ground, without the construction of the engine room, boiler room, safe and clean, the heat when heating is directly taken from the outdoor air, which can save energy. Applicability cooled module unit products fully absorb the international research and development foundation styling products designed mature domestic refrigeration, air conditioning on the latest developments in technology. The unit is designed and manufactured in strict accordance with the national industry standard, featuring world-renowned manufacturer of high quality, name brand compressor, fan, refrigerant system control components and computer control devices, through rational system matching and structural design, the unit at temperatures above -10 ℃ conditions effective heating products are widely applicable to require year-round air conditioning and winter load small North, South and Southwest, and some lack of regional water resources. At the same time some of the winter temperatures are relatively low and there is no heating boiler or other areas where conditions are particularly applicable. 2 Features editor saves space unit uses high efficiency heat exchanger, the use of advanced and special outdoor structure design and system matching. The unit is small, light weight, small footprint. Units can be installed directly on the roof or elsewhere outside without a separate machine room, saving space. Complete protection units are equipped with temperature protection switches, overload relays, high and low pressure safety switch, dry filters, antifreeze switch and delay start other protective devices to ensure host security, and reliability. All refrigeration parts and valves are international brand-name products, to enhance the operational reliability of the unit. The modular design of modular design, the unit can be in standard modular units for production and transportation. At the installation site combined into a complete unit, light standard module unit weight, small size, the unit transportation, installation and commissioning and maintenance easier, saving lifting, installation and operating costs. Modular air-cooled heat pump chillers, each refrigeration systems are independent of each other, each other back. Any abnormal situation refrigeration circuit will not affect the normal operation of other refrigerant circuit, the computer when a circuit fails, the standby state issued a directive by other circuit fault loop operation to succeed, refrigeration units, heating capacity remained relatively stable. Delicate and beautiful appearance with efficient air-side heat exchanger inner grooved copper tube and corrugated by the hydrophilic membrane material reinforced aluminum fins mechanically up tube is made with high efficiency, easy to knot gray, particularly difficult winter frost characteristics . Using "V" type coil design, space utilization, small unit size, and the coil surface wind speed is more evenly and effectively improve the airflow. Unit related components and piping systems have been reasonable layout, with "v" type coil and the overall structure design, the unit appearance is clear and smooth. Unit case by powder electrostatic spray, color uniformity, appearance. Users can choose their favorite color, you can choose to make stainless steel casing, corrosion and rust. To adapt to the harsh outdoor weather conditions to ensure the quality of the unit has a good appearance over the life cycle. Ultra low-noise high-efficiency semi-hermetic screw compressors, smooth operation, noise vibration. Imported axial fans, its overall impeller and external rotor motor design, simple structure compact, aerodynamic; sickle-cast aluminum impeller, the fan can operate efficiently at lower noise, even in the same state of short wind able to maintain good aerodynamic performance. Control advanced, stable quality, reliable performance units using compressors, fans, cooling system parts, computers and electronic control components are imported famous company's products, good quality, control accuracy, reliable performance. Heat pumps for a variety of possible bad working conditions adaptability, easy maintenance and high operating efficiency. The use of advanced microcomputer control technology, all Chinese human-machine interface display, friendly user interface. Users to understand the operation of the unit. High degree of automation, functional, unit commitment to achieve program management, timing control, pump management, centralized monitoring unit achieved full user and remote monitoring. Micro-controller with intelligent defrost, defrost accurately and effectively, to avoid heat loss. Along with troubleshooting, energy management, frost monitoring, operation mode and many automatic control functions to ensure efficient operation of the unit. At the same time the unit is also equipped with high and low pressure, antifreeze, oil temperature protection, overload protection, under equal inverse multiple security devices to ensure safe operation of the unit. Maintenance management, flexible and convenient to install the unit, can also be remotely controlled field control; unit uses an open architecture, its compressors, refrigeration parts and electronic control systems are placed in the lower part of the unit is an open architecture, no panels, repair space great staff out of convenience, easy maintenance easy. Imported energy efficient hermetic scroll compressor, piston compressor efficiency ratio is 10%, and has a smooth, vibration, anti-strike capability fluid characteristics. All modular units under centralized control computer controller, according to the load, adjust the number of operational modules, the unit cooling capacity and actual demand consistent, to achieve the best energy-saving effect. Press the number of the rational allocation by increased unit offload capabilities, to enhance part load efficiency of the unit, and in the winter heating, multi-head can effectively reduce the impact on the unit system defrost heat. 3 parts editor heat exchanger uses fully optimized design, reasonable structure, reliable operation, excellent performance; withstand shock, not deformed, refrigerant runs smooth, clear back to the oil pipeline, safe. World class compressor scroll compressor, low noise operation, using a suction best allocation structures, asymmetric scroll and a low amount of deformation of the fixed scroll and improve the energy efficiency, the use of the optimal motor cooling structure, roller bearings and dry bearings, improved reliability, and has a variety of protection; exhaust temperature protection, low pressure protection, over current protection, reverse phase protection. Fan with low noise axial fan, complemented by the use of efficient motors, further improve unit efficiency and reduce noise. Thermal expansion valve import world-class refrigeration parts - thermostatic expansion valve, by adjusting the system is too cold (hot) to adjust the degree of system flow, and this machine select dual thermostatic expansion valve to control the flow, cooling, heating separate control, the ability to adjust more uniform .
