1. High voltage protection　　The panel of the unit shows high-voltage protection. There are many reasons for this failure, which can be roughly divided into waterway system problems and unit component failure problems.1. Waterway system　　 Eliminate errors in engineering installation. If the unit is reported to be under high-pressure protection after a period of normal operation, the water volume is often too small. It may be that the Y-type filter is dirty or the casing is fouled. This requires separate investigation.　　 The specific steps for checking whether the Y-type filter is dirty are as follows:　　A. The host machine stops running, and the valves at the front and rear ends of the filter screen are closed to prevent a large amount of water from flowing out.　　B. Use a spanner wrench to unscrew the Y-shaped filter plug and pull out the filter.　　C. Rinse the filter in the tap water and put it back in the pipeline.　　D. Remember to open the front and rear valves before starting.If the filter is dirty, you need to consider the possibility of fouling of the casing, especially in areas with hard water quality, the possibility of fouling is higher. To check the fouling, you only need to disassemble the main unit to check the inlet and outlet pipes. If it is found that the high-pressure failure is caused by the scaling of the casing, you only need to contact a professional cleaner to clean the scale.2. Unit component failure　　 The common unit failure leads to a low possibility of reporting high-voltage protection, focusing on checking whether the fan is working normally,　　 ①If the fan does not rotate, the fan capacitance or relay may be damaged, just adjust the multimeter to the file or measure the on-off file to judge.　　 ②If the high-voltage switch is turned off immediately after the brake restarts, there is no doubt that the high-voltage switch itself is broken, just replace it.　　 ③ If the unit has been used for many years, the fins covered with dust may also cause high-voltage protection, and only need to clean up with water to eliminate the fault.

Air conditioner has become a necessity for every family when a hot summer. Because of "fluorine air conditioner" that destroys the earth's ozone layer, more consumers will choose the "water air conditioner" to heating and cooling house.What exactly is "water air conditioner"? which is widely popular by users, and has also been recommended by many experts? Let me have a description. Composed of two combined system of air source heat pump. As a star product of "water air conditioner", the dual system of air source heat pump is popular in the market. It is composed of an outdoor host (air source heat pump), terminal equipment (indoor heat exchange, refrigeration system), transmission and distribution system, and control system. It meets the needs of heating and cooling. The construction of the dual system  01 heat pump hostBefore selecting the heat pump host, it is best to know the local minimum temperature, water supply temperature and precipitation, door and window standards, etc. in advance to ensure the thermal insulation of the door and window.  02 Transmission and Distribution SystemThe transmission and distribution system includes energy storage buffer water tank, expansion water tank, water pump, pipeline valve, sub-catchment and water balances. The buffer water tank can increase the water capacity of the small system, store cold and heat, and the temperature of the system changes more smoothly, avoiding the frequent start and stop of the unit when the host is running at low load, and can effectively extend the service life of the host. 03 End SystemEnd systems include fan coils, low temperature radiators, floor heating, and capillary nets. 04Control systemThe control system includes power supply, control line and control switch, etc., and the control panel is wired control, wireless, and Internet of things intelligent control.Personalized comfort experience has gradually become the pursuit of many families. The air supply heat pump dual supply provides accurate temperature control, small indoor temperature fluctuations, quieter operation, high energy efficiency, and obvious energy-saving economic advantages. Advantages.01 multiple functionsAn air source heat pump system has multiple functions, there is no need of multiple installation of systems.The air source heat pump two systems has one source and two ends, and one heat source, which uses the heat pump unit to supply cold water in summer and hot water in winter. The two ends refer to the end system where the radiant heating end and the fan coil co-exist. 02 Better for energy efficiencyThe air source heat pump combined system has good energy-saving performance, and its operating cost is lower than the combination of multi-lined and wall-hung furnace in the fluorine system. The operating principle of the system is to drive the compressor with very little electric power in winter, absorb a large amount of low-temperature heat energy in the air and convert it into high-temperature heat energy, generate hot water not exceeding 55 ℃, and circulate as a heat medium in the dedicated floor heating pipeline. heat.03 more comfortableAfter the outdoor unit compresses the refrigerant, the cold and hot water generated by heat exchange with water is then exchanged with indoor air. The temperature difference during the heat exchange is only about 5 ° C, the wind is soft, the comfort is very high, and the moisture in the air is not easy to lose , The human body feels more natural and comfortable.04 Beautiful installation without occupying landTwo air source heat pumps are provided for concealed installation.In terms of heating, air source heat pumps are used to heat water, and then heat energy is transferred through floor heating pipes. The heat pump host heats the water and then introduces it into the floor heating pipe to transfer it to each room.In terms of refrigeration, the two power supplies are connected to the central air coil and erected on the ceiling. The air coil is connected to the air source heat pump host.

Be worth to decorate busy season at present, to common people, decorate is a very troublesome thing, once decorate wrong, money can hit water not only bleat, and in the next few years, in more than ten years, probably want to suffer at that time decorate undeserved and cause later trouble.To assure decorate quality and effect, common people has to spend a lot of idea to decorate on.For instance heating, become more warm, comfortable to indoor, in recent years not only northern dweller begins to install central heating in the home, the dweller of southern many areas, also begin to install central heating in the home.At present, there are at least a lot of heating equipment on the market, useful natural gas, also have electricity, dazzling eyes, see people dazzling, do not know how to choose.People cannot help but ask, after all what kind of heating terminal, had better use, suit a family to use most?Here, the author recommends air energy heat pump for everyone.So what exactly is an air energy heat pump?What are its advantages?Below, the author to our country air energy leading brand - Nulite New Energy production of intelligent frequency conversion heat pump as an example, to everyone to introduce.Air can heat pump is a kind of using small amounts of electricity to drive the compressor work, absorption of low temperature heat in the air, through the condenser and evaporator with a "heat" way, heat the cold water, hot water with the plastic pipe is transferred to the building, finally, floor heating, floor heating machine, fan coil units, such as heating the end, to provide indoor heating equipment.Compared with traditional heating equipment, the air energy heat pump, which does not use any fuel such as coal or natural gas and does not use the "electricity-heat" conversion mode, has the advantages of safety, environmental protection and energy saving. It is the main equipment of the "coal to electricity" project in north China.But the A+ heat pump is a kind of air energy heat pump specially developed for the north "coal to electricity" project.As a model developed for the northern market, in consideration of the cold weather in the north, the smart share variable frequency heat pump is internally applied with the latest air jet enthalpy increasing technology of New Energy, which ensures that the heat pump can still produce heat stablly under the condition of -25℃ without electric auxiliary heating, and can meet the heating and hot water demand of most areas in the north.Considering that frost weather is common in the north of China, A+ inverter heat pump is equipped with the unique anti-frost protection system and automatic defrosting technology of Nulite New Energy.When the outlet water temperature is lower than the set safe value, the system will automatically start the anti-freezing mode to prevent the water system from freezing.The automatic defrosting technology can automatically adjust the defrosting cycle and the beginning and end time of defrosting according to the ambient temperature, coil temperature and heating time.The strong cold-resistant capability of the smart frequency conversion heat pump not only ensures the efficiency of the heat pump in the low-temperature environment, but also greatly reduces the operating cost of the users.According to a survey conducted by Nulite New Energy in 2016 on 200 households in fangshan who converted from coal to electricity, the average electricity charge of each household is only 2,500 degrees after a winter (about 120 days) with New Energy air energy heat pump.According to the calculation of electricity cost of 0.49 yuan per time in Beijing at that time, the average household only needs more than 1,200 yuan of heating in a winter, which is much cheaper than burning coal.Although many villagers have reported that heating with an air-energy heat pump is more expensive than burning coal in the past.But according to Nulite New Energy investigation, this is mainly due to the limited amount of coal used in the past and the poor quality of heating, so the villagers are used to saving.With air energy heat pump is different, as long as there is electricity can start running, not out of the house can be a key to the indoor heating, heating quality is high, the price is not expensive, so many villagers have developed a 24 hours a day boot, go out also do not close the habit.In addition to the smart variable frequency air energy heat pump, which can provide both hot water and heating, Nulite New Energy also has nearly 100 household products (such as smart variable frequency air energy heat pump, which can provide heating and cooling services), which can meet the different needs of all kinds of people.
