  空气源热泵机组结霜会带来什么影响?空气源热泵机组
  What is the effect of frost on the air source heat pump?
  1.堵塞翅片间通道,增加空气流动阻力;
  Block the passage between the fins and increase the air flow resistance.
  2.增加换热器热阻,换热能力下降;
  Increase heat resistance for heat exchanger and decrease in heat exchange.
  3.频繁化霜,化霜不尽,化霜过程是一个空调运行过程,不仅不能制热水,同时还需要消耗原有的热水的能耗,排出的冻水返冲到保温水箱中,造成水温进一步下降;
  3. Frequent frost, the frost of frost process is an air-conditioning running process, not only can't hot water, also need to consume the old hot water energy consumption at the same time, the discharge frozen water recoil in the heat preservation water tank, water temperature decline further;
  4.蒸发温度下降,能效比降低,热泵运行性能恶化,直到不能正常工作。
  The evaporation temperature drops, the efficiency ratio decreases, the heat pump performance deteriorates until it is not working properly.
  5.由于机组不能正常工作给客户直接造成经济损失,直至产生对热泵产品的后怕情绪,影响其消费选择。
  Because the unit is not able to work properly to cause economic loss directly to the customer, until it produces the fear of the heat pump product, affect its consumption choice.
  空气源热泵除霜方法:
  Air source heat pump defrosting method:
  1、可以增加风机转速,增加排风量,结霜过程是先钢管结霜,后蒸发器翅片结霜,再蒸发器内侧结霜。
  It can increase the fan speed, increase the air quantity, the frost process is the steel pipe frosting, the rear evaporator fins, and the inside of the evaporator.
  2、换热面积增大,蒸发温度与环境温度的温差就比较小,这时就不容易结霜。
  The temperature difference between evaporation temperature and ambient temperature is relatively small when the heat transfer area is increased, and the frost is not easy.
  3、应用小循环系统使机组得到休息。缩减其化霜的时间,同时能保证蓄热水箱有足够温度的热水,并且确保提高能效比,但成本有所增加。
  3, use the small circulation system to get the crew to rest. Reduce the amount of time it takes to melt the cream, and ensure that the heat storage tank has enough hot water to warm the water, and make sure that it increases the energy efficiency, but the cost increases.
