Description

An air conditioner terminal device

technical field

The utility model belongs to the technical field of air conditioners, in particular to an air conditioner terminal device used for indoor heat transmission and humidity change.

Background technique

Most of the existing air-conditioning terminal devices still adopt the local convection heat exchange design, which uses different forms of nozzles to spray cold air outward for cooling. The advantages of this device are high cooling efficiency and rapid cooling of the room. The disadvantages are There is a strong sense of blowing, which makes people have a strong sense of discomfort, and there is a certain amount of operating noise, and if the filter element is not cleaned in time, it is easy to cause pollution of the air inlet pipe and reduce the indoor air quality, which will also affect the cooling speed.

Recently, the radiant air conditioner has gradually gained social attention. It adopts the method of radiation of the flat pipe network for heat exchange, but there are defects: the cooling of the room is very slow, and it usually takes more than 30 minutes to reach the room temperature, and it is easy to condense during cooling. It is easy to make the room decoration damp and moldy.

Utility model content

Purpose of the invention: The purpose of this utility model is to solve the deficiencies in the prior art, and provide an air conditioner terminal device, which can not only quickly adjust the temperature in the room, but also enable the air conditioner to operate with low noise and high thermal comfort.

Technical solution: An air conditioner terminal device of the utility model includes a fresh air unit, an air supply fan and a ventilation duct assembly. The fresh air unit is provided with a water-cooled heat exchanger, and the bottom of the water-cooled heat exchanger is provided with a first air inlet. The first air inlet is provided with a filter, and the top of the water-cooled heat exchanger is connected to the air supply fan through the air supply pipe; the entire ventilation duct assembly is distributed on the surface of the indoor ceiling in a plane, and the ventilation duct assembly includes a ventilation main pipe, a number of first ventilation Branch pipes and several ventilation branch pipes, one end of the main ventilation pipe is connected to the blower fan, a number of parallel first ventilation branch pipes are extended on the main ventilation pipe, and a number of parallel second ventilation branch pipes are also extended on each first ventilation branch pipe, each The ends of the first ventilation branch pipe and the second ventilation branch pipe are provided with air supply holes.

Further, in order to adjust the indoor air humidity, the fresh air unit also includes a return air duct, the second air inlet and air outlet of the return air duct are located on the indoor side wall, and a dehumidification fan is installed on the return air duct. Enter from the second air inlet and then return to the room through the air outlet after the operation of the dehumidification fan.

In order to reasonably adjust the indoor air temperature and humidity, a temperature sensor and a humidity sensor are installed on the indoor side wall, and the temperature sensor and the humidity sensor are connected to the processor and connected to the air supply fan and the dehumidification fan respectively.

Beneficial effects: the plurality of air supply holes in the utility model are distributed on the indoor roof in a plane, which occupies a small area and has wide applicability, and can be widely used in family rooms or offices; the cooling capacity per unit area is low, so small Wind speed air supply, low noise and no blowing feeling; in addition, the wind speed in the utility model is relatively weak, and the vertical distribution of temperature is hot at the bottom and cold at the top, and the thermal comfort is high; at the same time, the convective heat exchange method can be used The air speed adjusts the cooling efficiency, and the temperature of the cooling space is lowered faster than that of the radiation cooling.

detailed description

The technical solutions of the utility model are described in detail below, but the protection scope of the utility model is not limited to the embodiments.

As shown in Fig. 1 and Fig. 2, a kind of air conditioner end device of the present utility model comprises fresh air unit 2, blower fan 1 and ventilation pipe assembly 5, and fresh air unit 2 is provided with water-cooled heat exchanger 4, and water-cooled heat exchanger The bottom of 4 is provided with a first air inlet 13, and a filter 3 is arranged in the first air inlet 13, and the top of the water-cooled heat exchanger 4 is connected to the air blower 1 through an air supply pipe; the whole ventilation duct assembly 5 is distributed in a plane On the surface of the indoor ceiling, the ventilation duct assembly 5 includes a main ventilation pipe 51, a number of first ventilation branch pipes 52 and a number of ventilation branch pipes. Branch pipes 52, each first ventilation branch pipe 52 also extends with a number of parallel second ventilation branch pipes 53, and the ends of each first ventilation branch pipe 52 and second ventilation branch pipe 53 are provided with air supply holes 6 for blowing air downward.

In order to adjust the indoor air humidity, the fresh air unit 2 also includes a return air duct. The second air inlet 11 and air outlet 12 of the return air duct are all arranged on the indoor side wall. The second air inlet 11 enters through the operation of the dehumidification fan 10 and then returns to the room from the air outlet 12 . A temperature sensor 7 and a humidity sensor 9 are also installed on the indoor side wall. The temperature sensor 7 and the humidity sensor 9 are connected to the processor 8 and then connected to the air blower 1 and the dehumidification fan 10 respectively.

The outdoor air is first filtered by the fresh air unit 2, then refrigerated by the water-cooled heat exchanger 4, then pressurized by the air supply fan, then flows out from each air supply hole 6 through the ventilation duct assembly 5, and then is mixed with the hot air below the room. Perform free convection heat exchange, and finally create a temperature distribution form with high thermal comfort in the room where the top is cold and the bottom is hot. Since the cold air flows out from multiple air supply holes 6, and the flow rate of each air supply hole is only equivalent to 1/1 of the original n (n is the number of air supply holes), so the airflow velocity of a single air supply hole is relatively small. Such a structural design makes it basically free from noise and blowing sensation during operation. If the indoor humidity is high, the signal sent by the humidity sensor 9 will start the dehumidification ventilator to reduce the indoor humidity.

Concrete working principle of the present utility model is:

When the air conditioner is turned on, the air supply fan 1 will start to operate at the maximum power, and it will introduce fresh outdoor air from the first air inlet 13 into the fresh air unit 2, pass through the filter 3 for dehumidification and dust removal, and then pass through the water-cooled heat exchanger 4 for heat exchange Cold air is formed, and the cold air enters each air supply hole 6 through the ventilation duct assembly 5, and the cold air is sent to the indoor room.

At the same time, the temperature sensor 7 transmits the collected indoor temperature data to the processor 8 to adjust the operating power of the ventilator, and the humidity sensor 9 transmits the collected indoor humidity data to the processor 8, and the dehumidification is started and closed by the processor 8 The fan 10 performs a dehumidification operation to ensure that the indoor humidity reaches a level that makes people feel comfortable.
