Description

Technical Field

[0001] The utility model relates to a combined air conditioner, in particular to a temperature and humidity measuring structure in a process section of a combined air conditioner box. Background Art

[0002] The combined constant temperature and humidity air conditioning system is used to control the air temperature and humidity in the production workshop within the range of process requirements. It has the functions of purification, cooling, dehumidification, heating, humidification, etc. The combined constant temperature and humidity air conditioner does not have its own cold and heat source. It uses the chilled water provided by the centralized refrigeration station for cooling and dehumidification, and uses the saturated steam provided by the boiler system for heating and humidification. Since the combined constant temperature and humidity air conditioner accounts for a large proportion of the energy consumption in the enterprise, how to reduce the energy consumption of the air conditioning system under the premise of achieving precise control of temperature and humidity is a problem that the majority of engineering and technical personnel need to face and solve. Whether each process section of each combined air conditioner operates efficiently has a great impact on the energy consumption of air conditioning operation, and judging whether each process section operates efficiently requires accurate measurement of temperature and humidity, pressure difference, and temperature and pressure of the energy supply and return pipeline in the air conditioning box.

[0003] The temperature and humidity data before and after the air conditioner, heater, and humidifier are used in the air conditioner automatic control energy saving logic. At the same time, these temperature and humidity data are also needed to verify and calculate whether these process sections are operating efficiently and the actual cooling, heating, and humidification capacity. How to accurately measure the data of each process section during the implementation of air conditioner automatic control has always been a difficult problem for automatic control manufacturers.

[0004] At present, when measuring the temperature and humidity after each process section in the air-conditioning box, the common method is to drill a hole on the top or side of the air-conditioning box and insert the temperature and humidity sensor probe into the air-conditioning box to detect the temperature and humidity data. However, various forms of surface coolers and heaters in the inner cavity of the air-conditioning box currently have the phenomenon of uneven temperature and humidity on the air outlet side. Therefore, measuring a certain point alone in the back of these process sections cannot truly reflect the actual temperature and humidity state of the gas after being processed by the process section. If the actual state of the air after being processed by the process section needs to be detected, there must be a sufficient process section length and a mixing valve to achieve sufficient mixing of the gas before detection, but this will greatly increase the length of the air-conditioning box and the wind resistance in the box, resulting in a significant increase in the initial investment of the air-conditioning box and the energy consumption of subsequent operation. Alternatively, several temperature and humidity sensors are arranged on the same cross-section up and down and left and right in the back of each process section, and the detection average is used as the actual state value, but this method also has the problem of large initial investment and difficult installation. The relative humidity of the air after surface cooling is very high, which is easy to cause water ingress to the temperature and humidity sensor and other faults. Utility Model Content

Each temperature and humidity measurement structure includes a gas drainage pipe system and a temperature and humidity sensor 8. The gas drainage pipe system includes a gas drainage main pipe and multiple suction pipes 9. The gas drainage main pipe is installed on the top of the air-conditioning box 1. The gas drainage main pipe can be fixed on the top of the air-conditioning box 1 by multiple U-shaped clips. The gas drainage main pipe includes a connected confluence drainage section 10 and a drainage extension section 11. The confluence drainage section 10 and the drainage extension section 11 form an L shape. The confluence drainage section 10 extends along the width direction of the air-conditioning box 1, and the drainage extension section 11 extends along the length direction of the air-conditioning box 1. The end of the drainage extension section 11 is provided with a bend adapter 12, which is inserted downward into the air supply section 3 of the air-conditioning box 1 through the bend adapter 12. Multiple air intake pipes 9 are evenly spaced along the width direction of the rear section of the process section of the inner cavity of the air-conditioning box 1. Each air intake pipe 9 extends vertically. Each air intake pipe 9 is evenly spaced with multiple air intake holes 13. The bottom ends of the multiple air intake pipes 9 are respectively fixed on the bottom wall of the inner cavity of the air-conditioning box 1. The bottom ends of the air intake pipes 9 can be installed on the bottom wall of the inner cavity of the air-conditioning box 1 through a mounting seat. The mounting seat can be fixed on the bottom wall of the inner cavity of the air-conditioning box 1 by screw connection. The bottom ends of the air intake pipes 9 are sealed, and the bottom ends of the air intake pipes 9 can be fixed on the mounting seat by a U-shaped card. The top ends of the multiple air intake pipes 9 extend out of the top wall of the air-conditioning box 1 and converge at the converging drainage section 10. The top of the air-conditioning box 1 is perforated at the positions corresponding to each air intake pipe 9, and the air intake pipes 9 pass upward from the corresponding perforations to the top of the air-conditioning box 1. The end of the drainage extension section 11 is open and extends from the top of the air conditioning box 1 into the air supply section 3 . The temperature and humidity sensor 8 is arranged on the drainage extension section 11 .

[0020] The middle section of the drainage extension section 11 is cut and connected through an expansion joint 14.

[0021] According to specific needs, the temperature and humidity measurement structure can be set at the rear section of the process section where temperature and humidity need to be measured.

[0022] The following takes the setting of the temperature and humidity measurement structure in the rear section of the surface cooling section 5 as an example to illustrate its working process:

[0023] Three air intake pipes 9 can be evenly spaced in the width direction of the rear section of the surface cooling section 5 of the air conditioning box 1. During the operation of the combined air conditioning box, under the action of the fan 18 in the air conditioning box 1, the fresh air coming in from the fresh air inlet 15 and the return air coming in from the return air inlet 16 are mixed in the new return air mixing section 2, and then processed in turn by the filtering section 4, the surface cooling section 5, the heating section 6, and the humidifying section 7 to reach the air supply section 3, and finally the air after a series of treatments is sent out to the production site environment through the air supply port 17 of the air supply section 3. In this process, since the negative pressure of the air supply section 3 is greater than the negative pressure of each process section in front. The air processed by the surface cooling section 5 will automatically pass through the multiple air intake holes 13 on the three air intake pipes 9 and enter the three air intake pipes 9, and will be automatically sucked into the confluence and drainage section 10 for mixing, and then flow into the drainage extension section 11, and finally be sucked into the air supply section 3. When the air passes through the middle section of the drainage extension section 11, the temperature and humidity of the fully mixed gas is detected by the temperature and humidity sensor 8. Since the detected gas has been fully mixed, the temperature and humidity of the air treated by the surface cooling section 5 can be accurately detected. The entire detection process has low cost investment, and there is no need to increase the length of the process section to be detected and the air mixing valve. Therefore, accurate temperature and humidity data detection is achieved without increasing the initial investment of the air conditioner and the energy consumption during operation, providing reliable temperature and humidity data for the air conditioner energy-saving control strategy and the air conditioner equipment operation intelligent judgment strategy.
