Description

Technical Field

[0002] Central air conditioning consists of air handling equipment, heat and humidity treatment equipment, supply and return air ducts and various terminal air outlet units. The central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air conditioning system to offset the cooling and heating loads of the indoor environment.

[0003] The ground source heat pump central air conditioner is an efficient and energy-saving central air conditioning system. It uses the solar energy and geothermal energy absorbed by the shallow water source and soil on the earth's surface, realizes the functions of cooling and heating through the heat pump principle, and adopts an energy-saving and environmentally friendly ground source heat pump system. For example, CN209726443U discloses a central air conditioner with energy consumption metering. The power supply voltage and power current are sampled and calculated in real time by an electronic meter, and the calculated energy consumption value of the central air conditioner is imported into the energy consumption metering unit to obtain the energy consumption value of the central air conditioner. Under the action of the central processing unit, the energy consumption value of the central air conditioner is converted into an electrical signal and uploaded to the computer terminal through the wireless communication unit. The energy consumption value of the central air conditioner can be obtained by simply turning on the central air conditioner for a period of time, which brings great portability to the work of the detection personnel. The energy consumption value of the central air conditioner at different temperatures can be detected by the temperature detection unit, which improves the accuracy of subsequent energy consumption detection.

[0004] However, since the circuit board of the device is arranged in the shell, when the circuit board needs to be replaced and maintained, the shell must be disassembled before the circuit board can be taken out, which makes the circuit board inconvenient to install and disassemble. In addition, the circuit board and the surfaces of the components on its surface are not well protected. When used for a long time, impurities in the air passing through the shell are very easy to adhere to the surface of the circuit board and various components, which can easily cause malfunctions of the components on the circuit board and affect the service life of the circuit board.
