Description

TECHNICAL FIELD

[0001] The utility model belongs to air conditioning air supply technical field, concretely relates to a horizontal attached fan coil. BACKGROUND

[0002] Ventilation and air conditioning technology has developed for a hundred years, and there are three main air flow organization methods: one is to send air downward from the top at high speed, and to mix ventilation by dilution principle; another is to send air upward from the bottom at low speed, and to ventilate based on displacement principle. However, these methods have their own shortcomings. The attached ventilation technology utilizes the Coanda effect and the extended Coanda effect to deliver fresh air to the working area more effectively, meets the requirements of temperature, speed and concentration, and thus improves the temperature efficiency and the air quality of the working area. This ventilation method is suitable for various building spaces, such as hotel, office, shopping mall and the like, and by using the attached ventilation technology, the required air supply amount for cooling in summer is greatly reduced, the energy consumption of the air conditioning system is reduced, and the problem that hot air is difficult to reach the working area in winter indoor environment is effectively solved.

[0003] At present, in the building space using the fan coil unit, the attached air supply needs to be additionally connected with a section of air pipe with an elbow or a static pressure tank, and the above two methods will increase the energy consumption of the fan and compress the ceiling space. Therefore, the utility model mainly designs from three aspects of saving the building ceiling space, reducing the system energy consumption and ensuring that no condensate water appears during the attached air supply. Specifically, there are the following points: first, the horizontal concealed fan coil needs to be installed with a ceiling support, and the unit is large and occupies the ceiling space. Second, the additional elbow pipe or static pressure tank will bring additional local resistance, increase the energy consumption of the fan, increase the motor power and increase the system energy consumption. Third, if the traditional horizontal concealed fan coil is placed vertically, the condensate water will leak, which affects the hygiene and aesthetics of the building wall. SUMMARY
