Abstract

PURPOSE:To previously prevent an operation when installing conditions are wrong contrary to expectations by stopping an operation if the actual number of revolutions of an air-cooled fan corresponding to the atmospheric temperature does not fall a temporarily suitable number-of-revolutions range by previously deciding the range of the fan. CONSTITUTION:Since sending of refrigerant from a condenser 16 to an evaporator 10 is conducted according to a pressure difference, it is necessary to always maintain the outlet temperature of the condenser 16 at a fixed value to the evaporator 10 having a preset pressure. Thus, the outlet temperature of the condenser 16 is always detected by a sensor T6, and a controller 30 so controls the rotation of an air-cooled fan 17 that the outlet temperature is held constantly. In this case, since the tentative value of number of revolutions of the fan 17 can be calculated from the amount of heat added by a regenerator 12, a table of range of the numbers of revolutions allowed for the fan is previously made before an air conditioner is installed, and stored in a memory 32 in the controller 30.

In a cooling system of an air conditioner using an absorption refrigerator, a refrigerant vapor evaporated in a regenerator is condensed in a water-cooled condenser, and the condensed refrigerant is guided to an evaporator for evaporation. The cooling heat medium (usually water) that circulates between the fan coil unit provided in the room to be air-conditioned and the refrigerator is cooled by the latent heat of vaporization. On the other hand, the evaporated refrigerant vapor is operated in a cycle in which a water-cooled absorber absorbs the concentrated solution (absorption liquid) and returns it to the regenerator.

By the way, in the air conditioner according to the present invention, since the cooling of the absorber 20 and the condenser 16 is all performed by the air cooling fan 17, it goes without saying that the cooling capacity greatly depends on the outside air temperature. However, since the absorption refrigerating machine according to the present invention is installed outdoors, the operating state varies depending on the place where the air conditioner is installed even if operating under the same conditions. That is, the cooling capacity of the air-cooling fan is greatly affected by the ventilation of the cooling air in addition to being dependent on the outside air temperature. For example, when the outdoor unit is installed adjacent to the wall that surrounds the two sides, the ventilation is impaired. As a result, the air cooling capacity may be significantly reduced compared to the case where the air cooling fan is installed in a well-ventilated place, and the air cooling fan may have an abnormally high rotation speed.

By the way, the above air conditioner basically controls each container by controlling the temperature of each container except that the pump 23 is used to deliver the absorbing liquid from the absorber 20 to the regenerator 12. A pressure difference is created between them, and the refrigerant is sent out and circulated by the pressure difference. Therefore, the delivery of the refrigerant from the condenser 16 to the evaporator 10 is also performed by the pressure difference, so that the evaporator 10 having a preset pressure is supplied.
On the other hand, the outlet temperature of the condenser 16 needs to be always kept constant (45 ° C. in this embodiment). Therefore, the sensor T6 constantly detects the outlet temperature of the condenser 16, and the controller 30 controls the rotation of the air cooling fan 17 so that the outlet temperature is maintained at 45 ° C.
