Carbon dioxide (CO2) concentration control is usually the maximum air flow of new air handling units are (except to bear the load of the DC-style indoor unit) Press meet hygiene requirements and design, then press the number of rooms at full consideration. In actual use, the room number is not always full, and when a small number of people, fresh air can be reduced in order to save energy, this method is particularly suitable for certain uses fresh air plus air unit coil system of office building space small meeting rooms and other places use. In order to guarantee the basic quality of indoor air, indoor CO2 concentrations usually measured way to measure, as shown in Figure 4-43. CO2 concentration controller are located in each room to control the degree of opening of the electric valve on the new air manifold, while the system in order to prevent excessive hydrostatic brand new air handling units, fan speed controller setting static pressure on the total air pipe . Therefore, this will not only reduce the load of new air-cooled, and fan energy consumption will decline. The air conditioning unit box of high quality composite sandwich panels, appearance, rigidity, rust resistant, low noise, good sealing performance, good thermal insulation properties, are widely used in electronic instruments, precision machinery, pharmaceuticals, food , light industry, chemical industry, industrial air purification engineering, but also for the comfort of central air-conditioning engineering research buildings, restaurants, hotels, hospitals, commercial buildings, exhibition halls, theaters and other medium and large public buildings. The new wind blowing in the efficiency of the chassis unit selection, pressurized air box, clean air box is a free workshop to provide early, middle, air purification devices (high) efficiency filter, which has filtered air supply function, easy to install new air unit maintenance easy to use, the advantages of reasonable structure, to improve the process conditions, improve product quality and yield good results with a front-end equipment. The new wind plant design selection Description (1) with the air flow unit has several different forms of choice, primarily based on the size of the installation space, wind, air pressure and other requirements. For example: 5000m3 / h of wind turbine units can be 1 or two fans. 2.5 × 2.5 × 1, in the case of mounting pressure and noise conditions are met, try to use a small number of fans station crew. (2) This series of units is inhaled, cooling water temperature is not lower than 5 ℃, heating and hot water is not higher than 60 ℃, preferably demineralized water. (3) The unit should not bear the weight of the ducts and water pipes. (4) Units for the exchange of three-phase power supply 380V, 50HZ, there are individual single-phase 220V, 50HZ. (5) units such as the air inlet tube anemometer, should consider the possibility of the following flange connections necessary to elevate the unit. Around (6) units should leave space for maintenance over 0.8m, lifting the unit should be left manholes and repair space. (7) unit filled with water weighs about 1.3 × unit weight, shall provide the civil engineering unit carries weight requirements. (8) In addition to the sample according to the book model production, according to the air volumes of customers raised more than pressure, cooling (heating) capacity requirements and dimensions available.
