About SEJ motor and Holip controller: Three-phase asynchronous motor with magnetic brake has broad uses, It is suitable for various mechanical main drive and auxiliary drive, and it is also used for various required rapid stopping and correct positioning. The braking time within 0.2 second. Electric motor is added the DZM series direct current electromagnetic arrester by the basic series(Y series) electric motor.The protection class of electric motor part is IP44,the arrester part is IP23.if be applicable to bad environment can also make the arrester part into IP44,but customer have to put forward a special request while ordering,the manufactory can design a manufacturing exclusively. Its structure diagram is picture 1 and 2,picture 1 is the structure with hand release.Picture 2 is the structure without the hand release.Its operating principle BE, after being to make the retardation coil(6)to connect direct current power supply,because of the function of electromagnetic force,electromagnet(7)attract gag bit(5),and compress spring(24),make arrester disc(2)away from the friction surface of the gag bit(5)and shield(26)(the electrical motor can immediately operate normally).When the power supply cuts off after,the electromagnet(7)loses electromagnet force,the spring(24)releases the gag bit(5)and compress tightly to arrester disc(2),the arrester function,stop(the motor shaft)quickly,make electric motor shop turning to move,for the second time connect power supply will repeat above-mentioned action.

Heat pump from its name looks like a water pump, the pump is to raise the low water to high, then the heat pump can heat from low to high temperature end, the heat pump is a mechanical energy consumption, can not be used directly from low-temperature heat source, the temperature is 14,15 degrees, after the heat pump can become a direct source of high temperature heat, it is the heat of the condenser to heat cooling equipment. Heat pump unit has four main components, compressor, evaporator, condenser and throttling valve, the compressor in the summer when the hole end to the evaporator, and then the evaporator can absorb the heat of the room, through the compressor Pai to the ground. In winter, on the other hand, the end is connected to the condenser, which absorbs heat from the ground and evaporates into high-temperature and high-pressure gas which is then exchanged with the water in the room and sent to the room for winter The purpose of heating, heat pump not only cooling but also heating, while providing hot water throughout the year. Air source heat pump is a heat pump with air as a source of heat and heat. In the early 1980s, large and medium-sized air-source heat pump units started to enter the air-conditioning market in the Yangtze River Basin and its surrounding areas in our country. Driven by China's energy and environmental policies, the sales of air-source heat pumps appeared in the late 1990s The climax of development, which has promoted the users and relevant scientists and technologists to get acquainted with it more deeply and study it. Therefore, air source heat pump technology has become mature, and people in the industry have started to think how to explore optimization and improvement measures from the development and progress of modern science and technology . People have experienced in use, air source heat pump reliable energy saving, easy to install and use, but the summer outdoor air temperature is higher, people are in urgent need of air conditioning cooling, the cooling effect is worse, but the higher energy consumption, the unit's energy Consumption and air conditioning cooling effect is inversely proportional to the phenomenon, can be called "reverse effect." Moreover, outdoor air humidity in the Yangtze River Basin and its surrounding areas is relatively high in winter, leading to severe frost formation in the outdoor fin heat exchangers, leading to easy blockage of air flow between the fins and a decrease in exchange efficiency, thereby increasing the defrosting energy consumption of the units, and not Conducive to the heating unit. In addition, the application in large and medium-sized cities, there is a serious problem of noise pollution, can not meet the environmental requirements. The existing air source heat pump technology has made an important contribution to the energy saving and environmental protection of human society in the past half century. However, with the development and progress of modern science and technology, some optimization of this technology has been made The key to improved conditions is how to fundamentally solve and eliminate its shortcomings. For example, the problem of frequent defrosting in winter is that many enterprises make use of advanced high-tech computer technology. However, practice has proved that this is only a last resort and the solution to this problem is not satisfactory. The fundamental problems have not been solved and a misunderstanding that is unnecessary and impoverished in terms of intelligence and financial resources has been introduced. Objectively speaking, with the progress and development of modern science and technology, there really exist remedies, such as the use of hybrid air-source heat pumps and solar energy. The key to solving the above problems in the hot summer months, especially in the south, is the condenser, which can be air-cooled (sensible heat exchange) with dry-run finned-coil coils, air-cooled with finned coils in wet conditions, Evaporative Cooling of a Condenser Section Three-Stage Series Combined Composite Cooling Principle. In this way, summer outdoor air wet-bulb temperature can be taken as the main cooling parameter of the condenser to avoid adverse effects of summer dry-bulb temperature of outdoor high-temperature air and reduce the condensation temperature in the condenser. During summer cooling operation, if the dry air temperature of the outdoor air is raised to over 40 ° C, the condensing temperature may still be maintained at about 40 ° C and will not increase with the increase of the outdoor air dry-bulb temperature, so that the energy of the compressor Consumes 26% more than the existing air source heat pump, and can make the SEER of the unit higher during the cooling operation of the heat pump in the summer so as to achieve the normal cooling effect of the air conditioner and eliminate the influence of the air conditioner during the cooling process Reversal effect. Winter heating operation, frosting, defrosting is caused by air-source heat pump heating effect is poor and the main problem of increased power consumption, the use of composite air-source heat pump through the precooler to enter the unit of outdoor air dehumidification treatment to Reduce the degree of frost between coil fins, reduce the energy consumption of defrosting and prolong the defrosting cycle. At the same time, the unit uses the same gravity flow pipe, that is to say, the upper part of the outdoor heat exchanger is provided with liquid supply and air supply ports, and the liquid return and vapor return ports are provided from the lower part thereof. This is the unique gravity flow piping of the unit, which helps to ensure that the liquid refrigerant smoothly returns to the accumulator and the lubricating oil smoothly returns to the compressor crankcase. In addition, the units are equipped with low-noise centrifugal fan to control the noise level SPL (A) = 65dB or so, and to facilitate air-conditioning engineers to better noise processing. An additional impedance composite muffler, indoor noise levels can be achieved.
