First, the unit profile
Century Changlong sea water source heat pump unit with special anti-corrosion treatment, can be directly into the crew of seawater, due to the abolition of the expensive titanium alloy intermediate heat exchanger, not only greatly reduces the initial investment in equipment, and maximize the heat pump system Heat transfer efficiency, therefore, the century Changlong sea water source heat pump unit has an excellent price, but also created a sea water source heat pump application of a new era. The series of products using international brand-name semi-closed screw compressor, the use of the company's own patented technology developed by the sea water corrosion-resistant high-pressure high-pressure heat exchanger, R22 working fluid unit, the hot water when the maximum water temperature of 55 ℃ , Cold water cooling water temperature to a minimum of 5 ℃; R134a working fluid unit, heating water temperature of hot water up to 65 ℃, cold water cooling temperature to a minimum of 5 ℃. The unit adopts intelligent control, simple operation, high energy efficiency. The series is suitable for all kinds of offshore construction.
Second, the unit characteristics
◇ energy saving and environmental protection: the use of water as a cooling and heating medium, the unit of energy efficiency is high, save operating costs, and will not cause urban heat island effect and environmental pollution;
◇ super performance compressor: the use of international brand semi-closed screw compressor, smooth operation, low noise, small vibration, long life unit;
◇ advanced control system: powerful microcomputer controller with water source heat pump dedicated control program for the unit to provide a sound control function, digital calculus proportional control, greatly reducing the time to reach the rated cooling capacity, substantial energy saving;
◇ perfect operation interface: flip color LCD touch screen display, stable and reliable, real-time trend display, at any time to view the unit load conditions, easy management;
◇ safety protection device: high pressure, low pressure, oil pressure, oil level protection, antifreeze, water switch, compressor overload, power supply 4E protection;
◇ installation of convenience: the unit structure to pick up, covers an area of small; machine factory, the machine has filled the refrigerant, the unit evaporator and condenser has been laid insulation layer; water pipe with a clamp connection, And condenser water pipes and power supply can be, simple and convenient;
◇ group control function (option): can be equipped with powerful remote monitoring software, can achieve multiple units for temperature display, start and stop operation, parameter settings and many other functions of the control;
◇ OTC function (option): According to the ambient temperature changes automatically modify the system water and water temperature, substantial energy saving.
Third, the control system
Century Changlong screw unit all use the compiling function of the highly reliable German Siemens programmable controller. Can effectively control the system in all directions, whether it is the heat pump itself, or the circulating pump, submersible pumps, temperature, pressure, frequency converter, etc., PLC controller can be a good control of them. As long as the customer made a request, after programming PLC controller can be achieved. Moreover, the German Siemens PLC controller has a very good compatibility, you can easily achieve the building automation. At the same time, the product is equipped with a very easy to operate the Han was touch screen, all parameters are marked as Chinese characters, at a glance, very easy to operate. Han Xian touch screen excellent performance, high reliability, and Germany's Siemens PLC controller and temperature module composed of the best performance, the highest reliability of the control system to ensure that the heat pump system long-term, safe and reliable operation.
