Description
Technical Field
The utility model relates to an indoor unit technical field specifically indicates an energy-saving indoor set of ultra-thin silence.
Background
The fan coil mainly depends on the forced action of the fan to heat the air when the air passes through the surface of the surface cooler, thereby strengthening the heat convection between the surface cooler and the air and quickly heating the air in a room. The fan coil is a terminal device of an air conditioning system, and the working principle of the fan coil is that air in a room in which the fan coil is located is continuously recycled in a unit, so that the air is cooled (heated) after heat exchange with cold water (hot water) circulating in a surface air cooler, and the temperature of the room is kept constant; the main fan coil (non-four-side air outlet) in the current market comprises three types of horizontal concealed installation, horizontal exposed installation and ceiling embedded type fan coils, a water collecting head mode (left side and right side) needs to be explained when ordering generally, whether a wind returning box is arranged or not needs to be explained, if the wind returning box is arranged, a wind returning mode (back wind or down wind) needs to be explained, and the wind returning mode cannot be changed on an installation site.
The mainstream fan coil in the current market has the following defects:
1. the air return mode can not be changed on site, and when the design is changed on the right side of the installation site, the fan coil needs to be ordered again;
2. part of the water tray is exposed, and the water tray is easy to accumulate dust or other impurities and block a condensate water outlet;
3. the condensate water port is arranged at the bottom of the fan coil, so that inconvenience is brought to installation, and if the inclination angle of an installed drain pipe is insufficient or the water pipe is deformed, condensate water can flow back to the fan coil; meanwhile, the water outlet is arranged at the bottom of the unit, and the tail end of the water drainage pipe needs to be much lower than that of the unit to safely drain condensed water in the water tray, so that the use space of a user is reduced;
4. the fan coil water trays in the current market have two types, one type is that a water outlet is welded after a common steel plate or a galvanized plate is formed, the surface is sprayed with plastic, and the other type is that stainless steel is formed and the water outlet is welded; during assembly, a layer of heat insulation cotton is bonded outside the water tray, and the heat insulation cotton is directly exposed in the air in the use process. With the increase of the service time, the heat-insulating cotton is aged and the plastic spraying falls off, and the oxidation of the welding part is generated along with the aging, so that the use is influenced;
5. the surface cooler is vertically arranged, so that the thickness of the fan coil is larger (the thickness of the fan coil on the current market is about 240 plus 250mm) while the air return area and the air volume are met, the use space of a user is occupied, and the use space of the user is smaller in consideration of the inclination of the condensate water drain pipe; if a user needs an ultrathin fan coil, the current market mainly adopts a mode that under the condition that the unit length is not changed, the number of holes of a surface cooler is reduced, so that the heat exchange quantity is seriously insufficient, the requirement is met only by increasing the number of the units, and the energy consumption of the user is increased;
6. the metal volute and the impeller are connected through the fastening piece, and under the conditions of high-speed operation and slight vibration of the motor and after the motor is used for a period of time, the noise is increased due to vibration friction among metal pieces; (ii) a
7. The fins of the surface air cooler are in direct contact with the air for a long time, and floating objects in the air flow along with the air and are adhered to the air return side of the surface air cooler through the air return port, so that the fins of the surface air cooler are easy to block, and the air conditioning effect is reduced;
8. the common asynchronous motor is adopted, so that the unit can reach the required rotating speed immediately when being started, the service life of the motor is seriously influenced, and meanwhile, the vibration caused by starting enables the unit to easily generate noise and influences the use experience of a user;
9. according to some use habits, if the fan coil unit is continuously used under the condition that the window is opened, the use effect is poor, and energy waste is caused;
therefore, designing an indoor unit with excellent performance is an urgent problem to be solved by those skilled in the relevant field.
