Description

多工况变速调压空气源热泵热水器 Multi Gearshift regulating air source heat pump water heater

所属技术领域 Those of skill

:本发明涉及一种能在多种工况下都能正常运行的空气源热泵热水器;特别是涉及一种利用变速风机或风机组的可调节特性来调节蒸发器的蒸发量及吸气温度和工质工作压力,从而扩展热泵热水器的工况范围。 : The present invention relates to an air source heat pump water heater in a variety of conditions can be normal operation; particularly relates to an adjustable characteristic utilizing a variable speed fan or air unit to adjust the evaporation temperature of the evaporator and the intake air and pressure working fluids, to extend the operating range of a heat pump water heater.

背景技术 Background technique

:目前现有的空气源热泵热水器多是由压缩机、冷凝换热器、风机、蒸发器、节流装置和智能控制系统等部件所组成的,它是由风机蒸发器中的工质吸收室外空气的热量,经压缩机压缩后通过另一热交换器把所吸收的热量释放到水中,向用户供出50℃以上的生活热水。 : Currently available air source heat pump water heaters are mostly a compressor, a condensing heat exchanger, fan, evaporator, expansion device and the intelligent control system composed of parts, which is a working fluid in the evaporator fan absorbent outdoor heat from the air, compressed by another compressor after the heat absorbed heat released into the water, above 50 ℃ reveal the domestic hot water to a user. 其综合经济效益较高,环保节能效益特别好,由于热泵热水器自身的特性,大多安装在室外,因而会产生如下问题:室外气候在一年中变化很大,我国南北地区气候差别更大,使空气源热泵的工况调节复杂化。 Its high overall economic efficiency, environmental protection and energy efficiency are particularly good, because the heat pump water heater own characteristics, mostly installed outdoors, and they may be a problem: a large outdoor climate change in a year, more north-south differences in climate of the region, the air source heat pump operating conditions complicate the adjustment. 在环境温度低时,随着气温的下降,空气源热泵热水器的运行效率也急剧下降;另外,在相对湿度较高的地方,即使环境温度不太低时,如环境气温为5℃,室外与空气换热的冷凝器在换热过程中就会结霜,从而影响室外换热器的与空气的换热效率;而当环境温度高于30℃时,随着气温的升高,压缩机的吸气也不断升高,空气源热泵热水器的热效率则急剧下降,工质的工作压力不断攀升,此时压缩机不得不启动高压保护,停止压缩机工作,而此时热水器中的水还没有达到设定值,压缩机又需重新启动,如此反复不但降低了空气源热泵热水器的热效率,而且对压缩机的寿命严重损害。 At low ambient temperature, as temperatures drop, the operation efficiency of the air source heat pump water heater sharp decline; Further, where the relative humidity is high, even when the ambient temperature is not too low, such as environmental temperature of 5 ℃, outdoor and condenser air heat exchanger will frost in the heat exchange process, thus affecting the heat exchange efficiency of the outdoor air heat exchanger; and when the ambient temperature is higher than 30 ℃, at higher temperatures, the compressor suction also rising, the thermal efficiency air source heat pump water heater is a sharp decline, the working fluid pressure of work continues to rise, this time had to start the high-pressure compressor protection, the compressor stopped working, at a time when the water heater has not reached set value, and the need to restart the compressor, and so forth not only reduces the thermal efficiency of air source heat pump water heater, and the life of the compressor serious damage. 故此当环境温度35℃以上或低于-12℃以下时,空气源热泵热水器不能正常工作。 Therefore when the ambient temperature is above 35 ℃ or below -12 ℃ or less, air-source heat pump water heater does not work.

根据目前的压缩机及工质的特性就决定了,没有一种空气源热泵热水器既能适应40℃左右的高温工况、又能适应-12℃左右的低温工况。 According to the current characteristics of the working fluid compressor and decided, without an air source heat pump water heater can adapt to high temperature conditions of about 40 ℃, can adapt to the low temperature conditions of about -12 ℃. 针对以上问题,能否设计出一种既能在40℃以上的高温工况下正常运行、又能在-12℃以下的低温工况下正常运行的成本低、安全可靠的空气源热泵热水器,将成为亟待解决的问题。 To solve these problems, not only can design a high temperature above 40 ℃ normal operating conditions, but also under low temperature conditions and low cost of running below -12 ℃, safe and reliable air source heat pump water heater, will become a serious problem.

发明内容 SUMMARY

:为解决上述问题,本发明构造发明了一种多工况变速调压空气源热泵热水器及热水机组。 : To solve the above problems, the present invention is configured a multi invention Gearshift regulating air source heat pump water heaters and hot water unit. 即:利用变速风机或风机组的可调节特性,通过智能控制调节蒸发器的蒸发量来调节压缩机的吸气温度、从而轻松将空气源热泵热水器的工况范围扩展到-16℃-50℃,确保了空气源热泵热水器能适应多种工况下都能正常工作。 That is: the use of a variable speed fan or air unit can be adjusted characteristic, control and regulation of the evaporator by evaporation of the intelligent suction temperature of the compressor is adjusted, making it easy to extend the working range of air source heat pump water heater to -16 ℃ -50 ℃ to ensure that the air source heat pump water heater can adapt to a variety of conditions can work properly.

本发明解决的关键技术问题所采用的技术方案是:蒸发器的蒸发量主要由蒸发面积和空气迎面风速所决定的,如果改变其中的某一值,就会改变蒸发器的蒸发量。 The key aspect of the present invention to solve the technical problem is employed: evaporation evaporator mainly by evaporation area and air face velocity is determined, wherein if the change of a certain value, will change the amount of evaporation of the evaporator. 在实际使用过程中,蒸发器的蒸发面积一旦确定则不易改变,所以利用变速风机或风机组的可调节特性来调节蒸发器的空气迎面风速,从而达到调节蒸发器蒸发量的目的,在调节蒸发量的同时也调节了压缩机的吸气温度和排气温度以及工质的工作压力;具体来说:当环境温度不断上升时,压缩机的吸气温度也随之升高,此时降低风机或风机组的转速,则可减小蒸发器的蒸发量,使吸气温度不能再随着环境温度升高而升高,从而保证了压缩机正常工作所需的吸气温度。 In actual use, the evaporation area of ​​the evaporator, once determined is not easy to change, so the use of the variable speed fan or air unit can be adjusted characteristics of the conditioned air evaporator face velocity, so as to achieve the purpose of adjusting the evaporator evaporation in adjusting evaporation but also regulates the amount of intake air temperature and exhaust gas temperature and the working pressure of the working fluid compressor; specifically: when the ambient temperature is rising, the suction temperature of the compressor also will be increased, this time to lower the fan or wind speed unit, the evaporator evaporation may be reduced, so that the intake air temperature can not be raised as the ambient temperature rises, thus ensuring the normal operation of the compressor intake air temperature desired. 而当环境温度不断降低时,压缩机的吸气温度也随之降低,此时提高风机或风机组的转速,则可提高蒸发器的蒸发量,使吸气温度不能再随着环境温度降低而降低,从而保证了压缩机正常工作所需的吸气温度。 When the ambient temperature is continuously lowered, the suction temperature of the compressor is also reduced, this time to improve air handling units or fan speed can be increased by evaporation of the evaporator, the temperature of the intake decreases as the ambient temperature can not be reduced, thus ensuring the normal operation required by the compressor suction temperature.

实施方法;在标准工况下,热泵蒸发器变速风机或风机组中速运行;当环境温度低于标准工况温度时,变速风机或风机组高速运行,即可提高蒸发器的蒸发量,用来补偿由于环境温度过低所造成的吸气温度过低而对压缩机的影响;而当环境温度高于标准工况温度时,变速风机或风机组则低速运行,便可降低蒸发器的蒸发量,用来抵偿由于环境温度过高所造成的吸气温度过高而对压缩机的影响; The method of embodiment; speed running at standard conditions, the heat pump evaporator in a variable speed fan or air unit; when the ambient temperature is lower than the standard temperature conditions, the variable speed fan or wind speed operation unit, to increase the evaporation capacity of the evaporator, with Since the ambient temperature is too low to compensate for the intake air temperature is too low due to the influence of the compressor; and when the temperature is higher than the standard ambient temperature conditions, the variable speed fan or air unit is running at low speed, the evaporator can be reduced evaporation amount to compensate for the ambient temperature caused by excessive intake air temperature is too high impact on the compressor;
