Description
技术领域technical field
本实用新型涉及一种空调器。The utility model relates to an air conditioner.
背景技术Background technique
在当今社会，无论在工业、农业、军事、科研、教育、娱乐等各个方面，只要是需要空气调节的房间，就会有空调装置在运行，这样就消耗了大量的能源，况且大部分都是我们国家比较缺少的电力资源。在使用传统空调装置时，虽然对室内的温度起到了调节作用，可是由于空气是在室内循环，不能使室内被香烟的烟气、人体的浊气、装修的毒气污染了的空气得到净化和排放。而单纯的新风换气机主要功能在换风上，当室外温度在盛夏与室内温度相平衡或超过时，又起不到降温的作用。寒冬季节时，室外温度过低，在向室内送风时，由于温差过大，来不及热量交换就进入室内，将会大量损失室内的热量。有些房间为了达到调节温度和换新风的目的，不得不设置传统空调和新风换气机两台设备，设置传统空调和新风换气机两台设备，既要增加设备的投入又要增加电力的消耗。传统空调的冷凝器经常被杂物堵塞，导致冷凝器散热不良，甚至完全不能散热，使压缩机长时间工作也不能达到制冷效果，使压缩机过热，这是压缩机损坏的直接原因。In today's society, no matter in industry, agriculture, military, scientific research, education, entertainment, etc., as long as there is a room that needs air conditioning, there will be air conditioning devices running, which consumes a lot of energy, and most of them are Our country is relatively short of power resources. When using a traditional air conditioner, although it can regulate the indoor temperature, because the air is circulated indoors, the indoor air polluted by cigarette smoke, human body turbidity, and decoration gas cannot be purified and discharged. . The main function of the pure fresh air ventilator is to change the air. When the outdoor temperature is balanced or exceeds the indoor temperature in midsummer, it will not be able to cool down. In the cold winter season, when the outdoor temperature is too low, when the air is supplied to the room, due to the large temperature difference, it enters the room before heat exchange, and a large amount of indoor heat will be lost. In some rooms, in order to achieve the purpose of temperature adjustment and fresh air exchange, two devices, the traditional air conditioner and the fresh air ventilator, have to be installed, and the traditional air conditioner and the fresh air ventilator have to be installed, which will increase both equipment investment and power consumption . The condenser of the traditional air conditioner is often blocked by debris, resulting in poor heat dissipation of the condenser, or even no heat dissipation at all, so that the compressor cannot achieve cooling effect even if it works for a long time, causing the compressor to overheat, which is the direct cause of compressor damage.

工作原理：按中央控制器的指令来完成工作程序，用指令输入器21输入指令与室内温度传感器18、室外温度传感器19、交换器温度传感器20的温度参数进行比较后，中央控制器给出相应指令使与室外出风道12连接的排气变频风机5的风速进行调整及室外送风双向变频循环风机10进行无级调速，来满足热交换器4工作时达到最佳的热交换状态，热交换器4与室内风道1、室内排气风道6、室外进风道8和室外出风道12构成两个独立的系统，充分利用室外温度差实现调节室内温度及送新风的目的，送风冷却系统是由室外风道进风口避雨防尘帽9-1、室外风道进风口过滤器13、室内风道1、室外送风双向变频循环风机10、热交换器4、辅助加热器3、辅助制冷装置的蒸发器2和出风口导风板14连接组成的。排气系统是由室外风道出风口过滤器11、室外出风道出风口避雨防尘帽9-2、排气变频风机5、热交换器4、室内排气风道6、过滤器7和室外出风道12连接组成的。Working principle: Complete the work program according to the instructions of the central controller, and compare the temperature parameters of the indoor temperature sensor 18, outdoor temperature sensor 19, and exchanger temperature sensor 20 with the instruction input device 21, and the central controller will give the corresponding Instructions are used to adjust the wind speed of the exhaust frequency conversion fan 5 connected to the outdoor air outlet 12 and to perform stepless speed regulation of the outdoor air supply bidirectional frequency conversion circulation fan 10 to meet the best heat exchange state when the heat exchanger 4 is working. The heat exchanger 4 and the indoor air duct 1, the indoor exhaust air duct 6, the outdoor air inlet duct 8 and the outdoor air outlet duct 12 constitute two independent systems, which make full use of the outdoor temperature difference to achieve the purpose of adjusting the indoor temperature and sending fresh air. The air cooling system is composed of outdoor air duct air inlet rainproof dustproof cap 9-1, outdoor air duct air inlet filter 13, indoor air duct 1, outdoor air supply two-way frequency conversion circulating fan 10, heat exchanger 4, auxiliary heater 3. The evaporator 2 of the auxiliary refrigeration device is connected to the air guide plate 14 of the air outlet. The exhaust system is composed of an outdoor air duct air outlet filter 11, an outdoor air outlet air outlet rainproof and dustproof cap 9-2, an exhaust frequency conversion fan 5, a heat exchanger 4, an indoor exhaust air duct 6, and a filter 7 It is formed by being connected with the outdoor air outlet duct 12.
系统通电后，首先要通过“CPU”控制系统监测，分析判断室内外温度差及室内温度传感器18、室外温度传感器19、交换器温度传感器20检测到的温度数据进行比较后给出指令启动相应环节。当室内温度传感器18检测的温度值高于室外温度传感器19检测的温度值而低于指令单元设定的室内温度值时，满足空气交换装置启动条件，空气交换装置开始工作(在工作中为了防止热交换器发生结露现象，室内温度传感器18、室外温度传感器19、交换器温度传感器20监测到的温度同时送回CPU，分析比较后CPU再给出指令，调节室内外风道中的排气变频风机5和室外送风双向变频循环风机10，使室内外风道风量发生变化，防止结露现象发生)。当室内温度低于CPU设定的温度时，空气交换装置停止工作，只有极少数的天气里室内外温差不大的情况下，空气交换装置仍优先启动为室内降温。当室内外温度接近平衡(室内温度值≈室外温度值)时室内温度仍高于室内设定温度的情况下，辅助制冷装置启动继续为室内降温，达到设定控温点后停止工作，以后循环下去。After the system is powered on, it must first monitor through the "CPU" control system, analyze and judge the indoor and outdoor temperature difference and compare the temperature data detected by the indoor temperature sensor 18, outdoor temperature sensor 19, and exchanger temperature sensor 20, and then give instructions to start the corresponding link . When the temperature value detected by the indoor temperature sensor 18 is higher than the temperature value detected by the outdoor temperature sensor 19 and lower than the indoor temperature value set by the command unit, the air exchange device starting condition is met, and the air exchange device starts to work (in order to prevent When condensation occurs in the heat exchanger, the temperatures monitored by the indoor temperature sensor 18, outdoor temperature sensor 19, and exchanger temperature sensor 20 are sent back to the CPU at the same time. After analysis and comparison, the CPU gives instructions to adjust the exhaust frequency in the indoor and outdoor air ducts. The blower fan 5 and the two-way frequency conversion circulating fan 10 of the outdoor air supply make the air volume of the indoor and outdoor air ducts change to prevent dew condensation from taking place). When the indoor temperature is lower than the temperature set by the CPU, the air exchange device stops working. Only in rare weather when the indoor and outdoor temperature difference is not large, the air exchange device is still preferentially activated to cool down the room. When the indoor and outdoor temperatures are close to balance (indoor temperature value ≈ outdoor temperature value) and the indoor temperature is still higher than the indoor set temperature, the auxiliary refrigeration device starts to continue cooling the room, stops working after reaching the set temperature control point, and then cycles go down.
系统不会因室外环境不良如尘埃、树叶、树毛等物造成过滤器和热交换器堵塞。系统具有自动维护清理功能，过滤器是采用风向可逆原理，当正风向交换时，入口的过滤器会被杂物渐渐堵塞，继续工作下去滞留物增多，风量受阻就会使热交换器工作效率降低。利用变频风机可调整风速和风向，把开始滞留在热交换器一端的滞留物清理掉，而且正逆风交换不会影响系统热交换率下降，在工作的同时完成了清理工作。当热交换器下一次工作时，室外风机会反方向启动，入口变成出口时风向与上次相反，在工作的过程中把第一次工作时入口的吸附物清理掉，反复下去永远使热交换器两端的过滤器保持清洁。The system will not block the filter and heat exchanger due to bad outdoor environment such as dust, leaves, tree hair, etc. The system has the function of automatic maintenance and cleaning. The filter adopts the principle of reversible wind direction. When the positive wind direction is exchanged, the inlet filter will be gradually blocked by sundries, and the retention will increase as the work continues, and the air volume will be blocked, which will reduce the working efficiency of the heat exchanger. . The frequency conversion fan can be used to adjust the wind speed and wind direction to clean up the stranded matter at the end of the heat exchanger, and the forward and reverse wind exchange will not affect the decrease of the heat exchange rate of the system, and the cleaning work is completed while working. When the heat exchanger works next time, the outdoor fan will start in the opposite direction. When the inlet becomes the outlet, the wind direction will be opposite to that of the last time. The filters at both ends of the exchanger are kept clean.
