Description

Constant-humidity fan coil

Technical Field

The utility model relates to a constant humidity type fan coil belongs to fan coil technical field.

Background

The internal structure of the fan coil in the current market is basically the operation mode of a water coil and a fan. Cold water or hot water flows through the water inlet and outlet of the water coil, so that heat in the water is transferred to air through the coil fins, and the fan drives airflow to exchange the ambient air temperature with the heat of the coil fins. Thereby achieving the rise and fall of the ambient temperature. But the best comfortable environment for human body is achieved by not only regulating temperature, but also controlling humidity is very important. The relative humidity of the human body is 50% at 24 ℃ when the human body is in a static state (sitting still), and the human body feels relatively comfortable when the air slightly flows. Air conditioning and fan coils are generally used to condition air, but are not ideal for humidity control.

For example, 9-10 parts of the south China in 3-6 months, the temperature is 18-26 ℃ in a comfortable temperature state for a long time, but the relative humidity exceeds more than 75%, and the people feel very wet and have poor comfort. In this environment, neither the air conditioning or fan coil cooling or heating modes are appropriate. Therefore, the air plate for accurately adjusting the temperature and the humidity has a great market prospect.

In addition, the indoor and outdoor conditions in winter in the north belong to dry climates, and many families need to turn on a humidifier, for example, the air plate can also be provided with humidification, and the humidifier can be directly replaced.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 4: a constant humidity type fan coil is characterized by comprising a return air inlet 9 and an air outlet 10, wherein one side of the return air inlet 9 is provided with a tuyere compressor 1 and an electric cabinet 2, a V-shaped water coil 5 is arranged in the middle space between the return air inlet 9 and the air outlet 10, a fan volute 8 capable of driving air is arranged between the V-shaped water coil 5 and the return air inlet 9, the fan volute 8 is connected with a motor 7, one end of the fan volute 8 can absorb the air in the return air inlet 9, the other end of the fan volute 8 faces the V-shaped water coil 5, an evaporator and a condenser 6 are arranged between the air outlet 10 and the V-shaped water coil 5, a humidifying pipe 4 is arranged below the evaporator and the condenser 6, a water receiving disc 3 is arranged on the V-shaped water coil 5, a cool condensate water inlet 13 and a cool condensate water outlet 12 are arranged on the V-shaped water coil 5, a water receiving disc water outlet 14 is arranged at the lower end of the cool condensate water outlet 12, the whole machine is connected and fixed at a proper installation position through lifting lugs 11 and M10 screw rods on the periphery of the whole machine.

The lifting lug 11 is fixed by an M10 screw, a proper position is found and installed on a ceiling, a proper air channel and a proper space are reserved at the return air inlet 9 and the air outlet 10 for circulation of clear flow, air enters from the return air inlet 9 and rotates through the motor 7, the air is rapidly sucked into the fan volute 8, and then the air discharged from the fan volute 8 is blown onto the V-shaped water coil 5. The air is cooled or heated (determined by the inlet water temperature) through the V-shaped water coil 5. Then dehumidified (controllable) by an evaporator and a condenser 6, and humidified (controllable) by a humidifying pipe 4 to obtain the set temperature and humidity air to be discharged out of the room.

The temperature adjusting principle is as follows: the V-shaped water coil 5 needs to be externally connected with a water source (heat source), cold water at 7 ℃ is used for refrigeration, and hot water at 55 ℃ is used for heating. Cold water or hot water flows through the water inlet and the water outlet of the V-shaped water coil pipe 5. The heat in the water is transferred to the air by the coil fins, and the fan drives the airflow to exchange the ambient air temperature with the heat of the coil fins. Thereby achieving the rise and fall of the ambient temperature. The amount of heat exchanged can be controlled by controlling the flow of water in and out.

The dehumidification principle is as follows: by adopting the principle of Freon refrigeration dehumidification (namely, dehumidification by a Freon evaporator), when humid air passes through the surface of a preceding evaporator, the humid air is cooled on the surface of the evaporator, and after the humid air is cooled to a dew point temperature, water vapor in the air is separated out in the form of condensed water. The condensed water flows out through the water receiving tray. The dehumidified dry air is heated by heat recovered by the condenser and then discharged out of the machine, so that indoor heat load and temperature fluctuation are reduced, and energy is saved.
