Many manufacturers of air source heat pump where the installation instructions will be marked where unit running time, normal unit running time should not exceed 12 hours, then when the air source heat pump for a long time will happen? What serious consequences? These problems Fluid network Xiao Bian today to discuss with everyone about it. Interpretation of air source heat pump long run will produce what problems? Air source heat pump power and shutdown is set by the unit to achieve the temperature, when the unit has not reached the set temperature, the unit will be switched on; when the unit reaches the set temperature, the unit will stop in the body ; From which we can see that the start and stop of the unit is directly related to the set temperature. When using the unit, we should set the temperature reasonably according to the user's requirements. First, the air source heat pump long run how the air source heat pump for a long time, the unit itself is only harmful, unprofitable, long run, likely to cause electrical components aging, prone to short circuit, or burn the compressor; affect the unit Of the service life, proven by practice, long-running units tend to run shorter than the life within a reasonable range of 30%; the failure rate is about twice as high; run the unit at a reasonable time, the unit's life expectancy is often as high as 15 Year or above; low failure rate. Second, the causes of air source heat pump for a long time reasons 1, the unit selection is too small, many dealers, due to unreasonable selection, resulting in selection of models is too small, the user needs heat in the process, the unit can not provide enough Heat, causing the unit to run for a long time, or in order to ensure the profit point of the project to reduce the price of air-source heat pump, etc. Moreover, the user in order to reduce the cost of the previous investment, unit selection is too small, resulting in heat generating unit can not meet user calorie consumption Requirements, which caused the unit to run for a long time. 2, environmental climatic reasons, air-source heat pump heat by absorbing heat in the air, so it is with the lower ambient temperature, heat production will be reduced; many dealers in the selection process, did not take into account Unit operation in winter, the unit at lower temperatures to run, absorbing heat in the air to reduce the unit to obtain a single å± ring less heat, in order to achieve the same heat will make the unit longer working hours, it is recommended normal selection process Design work time is generally 10 to 15 hours. 3, the installation of the project is unreasonable, this is also caused by air source heat pump for a long time running reasons, for example, in the installation process, do not do the appropriate measures for unit ventilation, or exposed hot water pipes without the appropriate insulation measures, Invisible heat dissipated.
