Abstract

The invention discloses a method for controlling an outdoor fan of an air-conditioner. In the invention, the rotating speed of the outdoor fan is set into multiple grades from low to high, and can be adjusted at any time by combining outdoor environmental temperature (Ta) and condenser midpoint temperature (Tc); and the method comprises the following steps: the outdoor environmental temperature is detected at boot time, the outdoor fan selects the rotating speed with a corresponding grade according to the environmental temperature (Ta) to operate; and after boot running time T, the outdoor fan selects the rotating speed with a corresponding grade according to the condenser midpoint temperature (Tc) to operate. The invention ensures that the system pressure is always kept in a relative ideal voltage range, thereby preventing frequent start-stop of a compressor caused by too low system pressure; and the energy efficiency ratio of the unit is greatly improved, the service life is prolonged, and the outdoor fan does not need to operate at full speed all the time, thus further improving the energy conservation effect of the system.

Description

Method for controlling outdoor fan of air-conditioner
Technical field
The present invention relates to air-conditioning control field, specifically be meant a kind of control method of outdoor fan of air-conditioner.
Background technology
Air-conditioner generally comprises indoor set and two parts of off-premises station, comprise condenser and outdoor fan in the off-premises station, the effect of outdoor fan is that condenser is ventilated realizing the exchange heat of condenser and external environment, makes the pressure in condenser and the connecting pipe change thereby one of result of exchange heat is the gas liquefaction of the HTHP in the condenser.Existing outdoor fan of air-conditioner much still adopts full-speed operation and does not have speed regulating control, if off-premises station is not when operating at full capacity, this high-intensity exchange heat can cause system pressure low excessively, thereby low-voltage protective switch can cause the start and stop of high frequent, and then has influenced the life-span of unit; Only in ideal range, unit could obtain higher Energy Efficiency Ratio to whole system pressure on the other hand, and existing outdoor fan full-speed operation meeting often makes system pressure not in ideal range, makes that the Energy Efficiency Ratio of unit is low, and energy-saving effect is bad; Moreover be exactly that outdoor fan full-speed operation meeting causes condensator outlet liquid refrigerant degree of supercooling too big, and then cause the indoor set frosting, aggravation compressor return air band liquid, and follow and the concentration of lubricating oil deficiency occurs, compressor is caused the mortality injury.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of and can guarantee effectively that system is stable, prolongs unit durability and energy-saving effect method for controlling outdoor fan of air-conditioner preferably.
Technical solution of the present invention provides following a kind of method for controlling outdoor fan of air-conditioner.
A kind of method for controlling outdoor fan of air-conditioner is characterized in that: the rotating speed of outdoor fan is set at a plurality of grades from low to high, and the rotating speed of outdoor fan is adjusted at any time in conjunction with outdoor environment temperature and condenser neutral temperature, may further comprise the steps:
(1), when start, detect outdoor environment temperature, outdoor fan is according to the selected corresponding rotating speed operation of environment temperature;
(2), after the boot running time T, outdoor fan is according to the selected at any time corresponding rotating speed operation of condenser neutral temperature.
System pressure and outdoor environment temperature when the present invention utilizes start, the correlation of the existence of system pressure in service and condenser neutral temperature, outdoor fan is according to the selected corresponding rotating speed operation of outdoor environment temperature when start, and behind start operation certain hour, outdoor fan is according to the selected at any time corresponding rotating speed operation of condenser neutral temperature, thereby guarantee that system pressure remains in the pressure limit of a relative ideal always, thereby the low excessively high frequent start and stop that cause of system pressure have been avoided, and the Energy Efficiency Ratio of unit is improved greatly and prolong service life, and also full-speed operation always of outdoor fan has further improved the energy-saving effect of system.
As preferably, outdoor environment temperature is divided into third gear, during start, outdoor fan is selected corresponding rotating speed operation according to outdoor environment temperature place temperature gear, in the actual use of air-conditioning, mainly comprise refrigeration and heat two kinds of patterns, and corresponding environment temperature is divided into high temperature shelves, normal temperature shelves and three kinds of gears of low temperature shelves and can satisfies the demand, and the gear of branch can make also that too much system's control is complicated and impracticable.
As preferably, in this gear 60 seconds running times at least, this scheme is in order not cause the outdoor fan shift hunting to influence the life-span of blower fan behind the selected respective level rotating speed of described outdoor fan.
As improvement, in the outdoor fan running, when outdoor environment temperature when setting the maximum temperature limit value, the rotating speed of outdoor fan is not received the control of condenser neutral temperature, pressure is set at the maximum speed grade, when outdoor environment temperature surpasses the maximum temperature limit value of setting, according to result of the test as can be known, have only rotating speed to turn round at full speed and could guarantee system pressure as much as possible in ideal range, adopt this control scheme can further guarantee the stability of system outdoor fan
As preferably, in the outdoor fan running, when outdoor environment temperature when setting the minimum temperature limit value, the speed setting of outdoor fan is middle-bracket rotating speed, when outdoor environment temperature is lower than the minimum temperature limit value of setting, according to result of the test as can be known, do not need the rotation speed operation of outdoor fan with higher level, in this case, the maximum speed of qualification outdoor fan is that middle-bracket rotating speed can effectively improve energy-saving effect.
As preferably, 15 seconds≤T of boot running time≤300 seconds, boot running time is oversize or too shortly all can cause system pressure that bigger deviation is arranged, and suitable boot running time will help next step and adjust rotating speed according to the condenser neutral temperature.
