Operation and maintenance of combined air-conditioning unit
Brief introduction of combined air-conditioning function section:
Inlet section, combustion section:
The air inlet section is generally composed of an air outlet and an air valve that controls the opening of the air outlet. Usually, there are two parts, fresh air and return air. The new air outlet leads to the external environment, and the return air outlet leads to the treated space. The fresh air introduced by the fresh air inlet can effectively ensure the cleanliness of the air inside the room; the return air introduced by the return air outlet can make full use of the cooling or heat of the room to achieve the effect of energy saving.
Initial filter section:
The primary effect filter section is composed of the primary effect filter and the supporting frame. The primary effect filter is in the form of a plate type and a bag type, or a combination of the two. The characteristics of the plate type are simple installation and large dust capacity of the bag type. The role of the primary effect filter section is to filter out large particles of dust impurities in the air, so that the treated air is initially purified, which can greatly reduce the dust impurities on the equipment such as the surface cooler and fan, which plays a role in these equipment. Obvious protection. At the same time, it also reduces the burden of medium and high efficiency filters, and extends the service life of medium and high efficiency filters.
Table cold section:
The surface cooling section is composed of surface cooling devices of various specifications. At the same time, the surface cooling section is also equipped with condensate water collecting plate and water stopper. The size of the surface cooler is determined by the cooling requirement. The surface cooling section is used to reduce the absolute humidity of the air due to the precipitation of condensate in the case of refrigeration. The condensate water tray is used to accumulate condensate and drain the condensate out of the air conditioner through the drain elbow. There are two types of drainage bends, pipe bends and table tennis. The function of the water stopper is to prevent the condensed water from being brought into other air-conditioning sections by the flowing air.
Heating section: The function of the heating section is to heat the treated air, which can be used as a simple temperature increase in winter; it is used to regulate the air humidity in the transition season to achieve high humidity control requirements.
Medium-efficiency filter section: The medium-efficiency filter section is composed of a medium-efficiency filter and its supporting frame. Its function is to further filter out smaller dust and impurities in the air to achieve the function of further cleaning the air, and at the same time, it can extend the efficiency of the high-efficiency filter. effect.
High-efficiency filter section: The function of this section is to further filter the treated air, so that the air reaches a very high requirement.
Middle section: used for maintenance of air conditioner, generally equipped with maintenance door. At the same time, the middle section can achieve the uniform flow of the air flow, which has a great effect on stabilizing the air flow and mixing the hot and cold gases.
Differential pressure gauge: The differential pressure gauge can display the differential pressure between the front and rear sections, or the internal and external pressure difference of the air conditioner; used for pressure control monitoring of each filter section, or used to monitor the internal pressure of the air conditioner.
