Control method and apparatus for discharging condensed water from movable air conditioner

Abstract

A control method for discharging condensed water from a movable air conditioner is provided. No manual operation is necessary to empty the condensed water container. When the condensed water level is higher than a predetermined water level, the conditioner enters into a strong drainage mode operation. Condensing temperature increases and a pump for spraying is activated. The evaporating and draining speed increase as well. Evaporated condensed water will be discharged outdoor as air discharged from the condenser by the exhaust pipe; the rest of the condensed water will flow downward from the condenser to a water tank. When condensed water level bellows the predetermined water level, the conditioner exits the strong drainage mode and enters into a normal operation mode. The heat exchange efficiency of the condenser is also improved by utilizing the condensed water spray circulation system.

Description

FIELD OF THE INVENTION [0001] The present invention relates to an air conditioner, particularly relates to a movable air conditioner that is capable of discharging condensed water without manual operation. The present invention still relates to a control method for discharging condensed water from a movable air conditioner. BACKGROUND OF THE INVENTION [0002] During the cooling operation of a movable air conditioner, if the temperature of the evaporator surface is lower than the room temperature, humidity will be condensed out of the evaporator. There are two major methods used for discharging condensed water from a movable air conditioner in the market: one is directly collecting the condensed water into a water tank. Due to a limited volume, frequently, the water tank has to be emptied manually when it is full so that the water tank can be used again; typically, it takes one to two hours to fill up the water tank in a water condensing condition, it is very inconvenient during night...

AI Technical Summary

Benefits of technology

[0003] It is an object of the present invention to provide a movable air conditioner capable of discharging condensed water without manual operation by adjusting the air flow over condenser. It is to adjust the condensing temperature based on the water volume of the water tank to change the circulating air of the air conditioner condenser; therefore, the condensed water discharge rate is controlled, and the water tank will not be full, manual operation is not necessary.

[0006] When the condensed water of the evaporator flows to the condenser, the cooling efficiency of the condenser is enhanced. Due to high blast temperature of the compressor and the high cooling temperature of the condenser, some of the condensed water is evaporated and discharged outdoors by the exhaust pipe, and the rest will flow into the water tank.

[0009] When the water tank reaches the predetermined water level for draining, or the water level continues to be higher than the level for spraying for a predetermined amount of time, the water level regulator will signal the electronic control system, which will get into a stage of strong draining mode. That is the electronic control system activating the pump for spray circulation, and lowering the air intake of the condenser, raising the condensing temperature of the cooling system, and therefore raising the evaporation and exhaustion speed of the condensed water.

[0011] Usually, it is unable to reach sufficient discharging speed for the condensed water if the increase of condensing temperature is too small, and it will burden the system and wear out the protection and plastic members of the system if the increase of condensing temperature is too big. When the discharging speed of the condensed water is higher than the producing rate, the condensed water will be continuously evaporated and drained outdoor by the exhaust pipe, the water level of the water tank will decrease. When the water level of the water tank is lower than the water level of the spray, the system turns into a normal operation mode. Hence, the water tank of the present invention will not be full, manual operation is not required.

[0014] The condenser is provided under the evaporator; condensed water generated by the evaporator will flow downward to the condenser, and the heat exchange efficiency of the condenser can be improved.

[0018] 2. By utilizing the condensed water spray system, the heat exchange efficiency is increased and the operation power is decreased.

Problems solved by technology

Due to a limited volume, frequently, the water tank has to be emptied manually when it is full so that the water tank can be used again; typically, it takes one to two hours to fill up the water tank in a water condensing condition, it is very inconvenient during night time.

This operation extends the fill up time of a water tank, however, the condensed water is generated faster than the exhaustion rate during water condensing condition, the water tank will eventually be full and require manual operation to empty it; the typical fill up time is two to four hours.

Usually, it is unable to reach sufficient discharging speed for the condensed water if the increase of condensing temperature is too small, and it will burden the system and wear out the protection and plastic members of the system if the increase of condensing temperature is too big.
