How to solve the drainage problem of window air conditioner

Although window air conditioners are not common in life, some consumers still use them. We should also have some understanding of window air conditioners. Compared with split air conditioners, window air conditioners are very different in structure, so how to drain water for window air conditioners is a very difficult problem. Let's take a look.

　　 1. Understanding of window air conditioners

The principle of window type air conditioner and split type air conditioner is the same, the same is through four processes: compression, condensation, throttling, evaporation, etc., so that the refrigerant can complete the conversion between gaseous and liquid in the system. The complete difference is that the window air conditioner is a whole, without separating the indoor and outdoor, but it is still half inside and the other half outside.

　　 2. The structure of the window air conditioner

　　1. Chassis: It is composed of a box, a front panel, and an air filter;

　　’ 　　2. Refrigeration system: Compressor, condenser, evaporator, capillary tube, pipeline, filter, etc. constitute a fully enclosed refrigeration system;

　　3, fan device: composed of fan motor, axial fan, and centrifugal fan;

　　4. Operation control device: It is composed of capacitor, thermostat, control switch, overload protector, etc.

　　 Three, the three stages of window air conditioning drainage

1. Early window air conditioners had drains and connections for drain pipes (a small piece of pipe with a diameter of about 8mm). When installing, the indoor end of the air conditioner must be higher than the outdoor end. Because the drain is outside the window, there is no need to connect it. The hose, the condensed water can be directly dripped to the ground (people often encounter the situation of window air conditioners dripping at the root of the wall), and the hose can also be organized to drain.

2. Around the end of the 1980s, "energy-saving window-type air conditioners" appeared. The main purpose was to appropriately deepen the internal drain pan, so that the water level of the condensed water in the drain pan can reach the fan blades. When working, the blades bring out the accumulated condensate water And sprinkled on the radiator, the evaporation of water on the radiator increases the efficiency, thereby achieving the purpose of energy saving. At the same time, because the condensed water is consumed by the radiator, there is no excess water to be discharged outside, so it is also called "no Dripping air conditioning".

　　3. The window-type air conditioner produced in the later stage is basically of this style: there is condensed water, but it is used, not drained, and there is no drainage interface. In order to improve the heat dissipation effect, some brands of window air conditioners are specifically designed to use fan blades to pump the accumulated condensate onto the heat sink for cooling, so that there is no need to connect to a drain pipe.

Incidentally, if this type of window air conditioner is installed at too high an inclination, when the water in the water-saving pan overflows before being carried by the fan blades, it will still drip outside. The hole at the bottom of the casing is to prevent installation errors. , Water can flow out from here, and prevent water from accumulating in the rack.

　　 Window type air conditioners are different in structure from split air conditioners, so some functional designs of the products are also different. The treatment of the drainage problem of the window air conditioner also has its own uniqueness, and the design also tends to be perfect. After reading this, do you know how to drain the window air conditioner?
