Air conditioning equipment and fan coil condensate pumping device

The present invention relates to the field of air conditioning equipment, and in particular to a fan coil condensate pumping device. The present invention also relates to an air conditioning apparatus including the above-described fan coil condensate pumping device.

When the air conditioning equipment is cooling, the fan coil in the air conditioning equipment continuously circulates the air in the room, so that the air is cooled through the cold water pipe to reduce the temperature in the room. At this time, the temperature in the cold water pipe and the temperature outside the pipe are lowered. The difference is large, and it is easy to form condensed water outside the wall of the cold water pipe. If the condensed water accumulates too much water, it will cause water leakage and even damage the equipment.

At present, in a method for solving the problem of condensed water accumulation, a pump is installed at the end of the fan coil and a float device capable of transmitting signals with the pump, and when the water level rises to a certain height, the float device is triggered, and then the float is used. The signal from the device turns on the pump.

However, when installing the float device, it is necessary to calculate the installation position reasonably. If the installation position is too high, the condensation water will be too much, and it will overflow if it is too dry. Even if the installation position is low, the induction capacity of the float device is low. Pumping is not thorough enough. In addition, when in use, the fan coil is operated in the cooling mode to turn on the pump, and the pump is continuously pumping condensate. In other words, the pump is always running in the cooling mode and runs for a long time. It will affect the motor of the pump. After the condensate is pumped out, the pump will continue to pump water, which will cause waste of electricity.

Therefore, how to improve the treatment effect of the condensed water accumulated in the fan coil is a technical problem that needs to be solved by those skilled in the art.

In view of this, the purpose of the present invention is to provide a fan coil condensate pumping device, which has better treatment effect on condensed water.

Another object of the present invention is to provide an air conditioning apparatus including the above-described fan coil condensate pumping device, in which the condensed water of the fan coil is effectively treated.

In order to achieve the above object, the present invention provides the following technical solution: a fan coil condensate water pumping device, comprising: a tray for collecting condensed water; a water pump connected to a drain port of the tray; an inductive component, a system And on the inner bottom wall of the tray for sensing the water accumulated on the tray and controlling the start and stop of the pump; and the control unit connecting the induction unit and the water pump.

In a specific embodiment of the fan coil condensate pumping device provided by the present invention, the pump 4, the tray 2, the control unit and the sensing component are included. In use, the fan coil 1 is installed in the tray 2. When the fan coil 1 is cooled, the cooling water conveyed by the main unit is circulated in the cold water pipe 3, and the temperature in the cold water pipe 3 is lower than the temperature outside the cold water pipe 3, in the cold water. The condensed water formed outside the pipe 3 falls into the tray 2 to form condensed water. Preferably, the inner bottom wall of the tray 2 may have a smooth wall surface to ensure the smooth flow of the accumulated water. The water pump 4 is connected to the drain port 21 of the tray 2, and the sensing member is provided on the inner bottom wall of the tray 2 for sensing the accumulation of water on the tray 2, and the sensing member can control the start/stop of the water pump 4.

When there is water accumulated on the tray 2, the induction member and the control member can control the operation of the water pump 4, so that the water pump 4 draws out the water accumulated in the tray 2.

Since the inductive component is disposed on the inner bottom wall of the tray 2, when there is accumulated water in the tray 2, the inductive component can sense the accumulated water more quickly and control the start of the pump 4, so that the pump 4 draws out the water in the tray 2 in a timely manner. When the water in the tray 2 is excessively caused to cause the water to overflow the tray 2 or the water accumulated in the tray 2 is small, the water treatment is not clean. It can be seen that the fan coil condensate pumping device has a better treatment effect on the condensed water accumulated in the fan coil 1.

The sensing components in the above embodiments have a variety of specific options. Preferably, the inductive component may comprise two electrodes 5, each of which is in close contact with the inner bottom wall of the tray 2, wherein one of the electrodes 5 is connected to the pump 4 and the other An electrode 5 is connected to the control unit. The two electrodes 5 are in close contact with the inner bottom wall of the tray 2, and the sensitivity of the induction of water accumulated in the tray 2 can be ensured. When the two electrodes 5 are electrically connected by the condensed water, the circuit between the two electrodes 5 is It is connected to control the operation of the water pump 4 and the discharge of the water in a simple and effective manner.

Specifically, the control components in the above various embodiments may include a fan coil controller 6 and a relay 7, which can control the operation of the fan coil 1 and the pump 4, and at the same time, the fan coil control The heater 6 can supply power to the pump 4, and the relay 7 is connected between the fan coil controller 6 and the pump 4, that is, the fan coil controller 6 sends a control command to the relay 7 to implement the fan tray. The control of the communication between the tube controller 6 and the pump 4, the operation of the pump 4 is directly controlled by both the relay 7 and the electrode 5. The setting of the relay 7 is beneficial to protect the safety of the circuit. At the same time, by setting the control logic of the fan coil controller 6, the pump 4 can be operated for different states of the fan coil 1, and the setting is simple and convenient, and the control effect is good. . Of course, the setting of the control means is not limited to the mode in this embodiment.
