Air conditioning equipment with humidity adjustment

This case relates to an air conditioning device, especially an air conditioning device with a humidity adjustment function.

With the rapid growth of technology, the most popular new technology era term "cloud computing" is nowadays. In fact, cloud computing is not a technology but a concept. It is a kind of network communication type developed based on the application of computer technology. It provides various technical performance services by the remote end, which is essentially a decentralized operation. Distributed computing). The so-called decentralized operation is to let multiple computers, such as two or hundreds of thousands of units, simultaneously perform operations through mutual communication to complete the instructions given by the user. Generally, the cloud computing service provides an online commercial application accessed by a universal browser, so that a large amount of system software and data are stored in a remote large data center, thereby reducing the burden on each terminal computer hardware device. At present, the data center is combined with the concept of a green computer room. Through centralized management and virtualization of servers, storage and networking equipment, the floor space and power consumption are reduced due to excessive idle machines, and the servers in the equipment room are The correct design of power generation and air conditioning equipment further reduces heat dissipation and controls power consumption.

Many electronic devices generally installed in the data center are provided with circuit boards and electronic components. If the surrounding environment of the data center is too dry, the circuit board and electronic components are between It is easy to generate static electricity and cause damage, or the surrounding environment is too humid. Circuit boards and electronic components are prone to rust in the environment for a long time. Therefore, the data center must be equipped with high-efficiency constant temperature and humidity air conditioning equipment. From the past experience and general knowledge, when the air is in a relatively high temperature state, the effect of humidifying it is remarkable, but at the same time, it can achieve the purpose of cooling the air and humidifying the air if necessary. The constant humidity air-conditioning equipment is internally provided with a partition for separating into a main flow path and a bypass flow path, wherein the cooling element is disposed on the main flow path, so that a part of the hot air enters through the air inlet and is heated by the cooling element. The exchange is to achieve a cooling effect, and another part of the high-temperature air stream that is not heat-exchanged by the cooling element flows through the humidifier through the bypass flow path to perform the humidification function in time.

However, when the humidity in the air is stable and no humidification is required, part of the hot air will still flow through the bypass flow path, so that the hot air in the part is mixed into the cold air of the main channel exit, causing the already cooled. The cold air temperature rises again, and thus the overall air supply efficiency of the device is not effectively utilized.

In addition, since the conventional constant temperature and humidity air-conditioning apparatus additionally has a partition inside, when the volume of the air-conditioning apparatus is constant and the air flow rate is fixed, the space available for the cooling element is reduced, and the air flow rate capable of heat exchange is also reduced.

Therefore, how to develop an air conditioning device with the humidity adjustment function that can solve the problems and the problems encountered by the above-mentioned prior art is an urgent problem to be solved.

In this embodiment, the heat transfer medium may be water or a refrigerant, but is not limited thereto.

The third figure A shows the structural diagram of simultaneously opening the valve body and closing the humidifying device when the air conditioning device exchanges heat with the input airflow. As shown in FIG. 1B and FIG. 3A, when a sensor (not shown) installed in or outside the air conditioner 2 measures to determine that the outside air is in a state where it does not need to be humidified, the sensor transmits one. The sensing signal is sent to the controller 24 of the air conditioning device 2, and the controller 24 connected to the humidifying device 22 and the valve body 2120 will generate a control signal for sensing the signal to control the opening of the valve body 2120 and the closing of the humidifying device 22 .
