技术领域 technical field
本发明涉及空调通风技术，具体涉及一种空调箱，适用于各种对新风量有精确控制要求、可再设定大小需求的空调***。 The invention relates to air-conditioning ventilation technology, in particular to an air-conditioning box, which is suitable for various air-conditioning systems that require precise control of fresh air volume and reconfigurable size requirements.
背景技术 Background technique
我国建筑能耗占总能耗的30％左右，建筑能耗中，空调能耗占很大比例。对于全空气空调***，新风能耗占空调***总能耗的1/3左右，因此新风量大小的精确控制直接关乎空调***的总能耗。 The energy consumption of buildings in my country accounts for about 30% of the total energy consumption, and the energy consumption of air conditioners accounts for a large proportion of the energy consumption of buildings. For an all-air air-conditioning system, the energy consumption of fresh air accounts for about 1/3 of the total energy consumption of the air-conditioning system, so the precise control of the amount of fresh air is directly related to the total energy consumption of the air-conditioning system.
过渡季节，室外空气参数满足新风免费冷却要求时，空调箱应具有加大新风量，采用新风免费冷却以降低***能耗和运行费用的功能；非过渡季节，新风量应满足最小新风量需求，以保证室内空气品质，因此新风量大小应根据具体工况条件可进行再设定。 In transitional seasons, when the outdoor air parameters meet the fresh air free cooling requirements, the air conditioning box should have the function of increasing the fresh air volume and using fresh air free cooling to reduce system energy consumption and operating costs; in non-transitional seasons, the fresh air volume should meet the minimum fresh air volume requirements, In order to ensure the indoor air quality, the fresh air volume should be re-set according to specific working conditions.
现有空调箱不具备新风量大小精确控制功能，本发明可控制新风量大小为预先设置的恒定值，同时根据工况需求可再设定新风量大小，控制新风量为新设置的恒定值，在确保空气品质前提下达到空调***节能目的。 The existing air conditioning box does not have the precise control function of the fresh air volume. The present invention can control the fresh air volume to a preset constant value. At the same time, the fresh air volume can be re-set according to the working conditions, and the fresh air volume can be controlled to a newly set constant value. On the premise of ensuring the air quality, the energy-saving purpose of the air-conditioning system can be achieved.

The sections are arranged and connected from upstream to downstream in sequence. The fresh air pipe and the return air pipe are located on the new return air section, the fresh air two-position electric air valve is located on the pipe on. The actuator is located on the return air electric regulating air valve, the negative pressure measuring tube is placed at a place where the pressure is stable in the new return air section, the zero pressure measuring tube is placed at a place where the outdoor pressure is stable, and the negative pressure measuring tube The zero-pressure pressure measuring tube is connected to a differential pressure sensor, and the differential pressure sensor is connected to a controller, and the controller outputs a signal to the actuator of the return air electric regulating damper.
上述方案中，压差传感器和控制器可放置在室内或室外。鉴于维修方便，压差传感器和控制器优选安装在室外。 In the above solution, the differential pressure sensor and controller can be placed indoors or outdoors. In view of the convenience of maintenance, the differential pressure sensor and controller are preferably installed outdoors.
上述技术方案中，新风管阻力一定条件下，新回风段和室外侧空气压差值与新风量大小为一一对应关系。根据***所需新风量大小，得出其对应的压差值，通过调节回风管风阀开度使得空调箱新回风段和室外侧压差达到设置值，从而保证新风量为所需恒定值。 In the above technical solution, under a certain condition of the resistance of the fresh air duct, the air pressure difference between the fresh air return section and the outdoor side is in a one-to-one correspondence with the fresh air volume. According to the fresh air volume required by the system, the corresponding pressure difference value is obtained, and the pressure difference between the new air return section of the air conditioning box and the outdoor side reaches the set value by adjusting the opening of the return air pipe damper, so as to ensure that the fresh air volume is a required constant value .
由于上述技术方案运用，本发明与现有技术相比具有下列优点：本发明通过在新回风段增加负压测压管、室外侧增加零压测压管，将负压测压管和零压测压管测得的压力值传输到压差传感器，压差传感器将信号传递至控制器，通过控制器控制回风电动调节风阀上的执行器，调节回风电动调节风阀开度使得压差为设置的恒定值，从而实现新风量大小的精确控制。工况变化时，新风量大小可进行再设定，根据其对应的压差大小，调节回风电动调节风阀开度使得新风量为新设定的恒定值。 Due to the application of the above-mentioned technical solutions, the present invention has the following advantages compared with the prior art: the present invention adds a negative pressure pressure measuring tube to the new air return section and a zero pressure pressure measuring tube outside the outdoor, and combines the negative pressure pressure measuring tube and the zero pressure measuring tube. The pressure value measured by the pressure measuring tube is transmitted to the differential pressure sensor, and the differential pressure sensor transmits the signal to the controller, and the controller controls the actuator on the return air electric adjustment damper to adjust the opening of the return air electric adjustment damper so that The pressure difference is a set constant value, so as to realize the precise control of the fresh air volume. When the working conditions change, the fresh air volume can be re-set. According to the corresponding pressure difference, adjust the opening of the return air electric adjustment damper so that the fresh air volume is a newly set constant value.
