In addition to the direct-current system, new air handling units are usually used in conjunction with the fan coil. In some projects, considering a variety of reasons (such as fan coil dehumidification capacity restrictions, etc.), new air units to bear part of the burden of indoor air unit in the new horizontal design, this approach to the design of the state, according to a new air unit supply air temperature control is non-existent problem. But climate change and making the indoor outdoor reaches thermal equilibrium (such as some time transition season) fresh air unit, if it continues to control the supply air temperature specifications of the new air unit, will inevitably lead to the room too cold (when cooling hydraulic conditions) or overheating (heating When the hydraulic conditions), then the indoor temperature control should be used. Therefore, in this case, from the full-year run, it should adopt the joint control of air temperature and room temperature. Check before starting a project, check the fan drive belt is loose, to be replaced over time as the extension 2CM hand taut. 2. Check the fan and motor bearings are normal, filling a lubricant (optional models). 3. Check the condenser coil is clean, drain pan outlet offer anything on the new air unit, if you want to clean and clear. 4, check the heater is normal, voltage and resistance measurements, such as abnormal to be repaired or replaced. 5, in the presence of other abnormalities inspection machine, the inner panel is sealed after installation. 6. Check the filter seal and leakage 7, check into the wind, blowing fresh air damper unit is quoted in the open state | Altay new wind generating units | Rui Xincheng Rui Xincheng air conditioning provided by the Texas Air Conditioning Equipment Co., Ltd ..
