Multi-connected chilled beam air conditioning system with variable refrigerant flow

Abstract

The invention relates to the technical field of central air conditioners, and discloses a variable refrigerant flow multi-connected chilled beam air conditioning system which comprises a direct-current variable-frequency multi-connected air conditioner outdoor unit, a multifunctional air conditioning box, a chilled beam, a temperature controller, a refrigerant copper pipe and a branch pipe. The multifunctional air conditioning box and the chilled beam are connected with the direct-current variable-frequency multi-connected air conditioner outdoor unit through the refrigerant copper pipes and the branch pipes, and the multiple sets of segmented refrigerant copper pipes are connected with one another through the branch pipes. The multifunctional air handling unit can be installed in suspended ceilings in areas such as indoor aisles, toilets, kitchens and equipment rooms, the silencer is installed on the air supply main pipe, noise is reduced as much as possible, and the height of the built-in suspended ceilings is not affected due to the fact that the multifunctional air handling unit is miniaturized and the size of the air supply and return pipe is small. In winter, hot water is prepared through a refrigerant-water heat exchange module arranged in the direct-current variable-frequency multi-connected air conditioner outdoor unit and supplied to a floor heating system. An air conditioner system, a floor heating system and a fresh air system are integrated in one system.

Description

technical field [0001] The invention relates to the technical field of central air conditioning, in particular to a variable refrigerant flow multi-connected chilled beam air conditioning system. Background technique [0002] The end of the VRV multi-connected central air conditioner is a fan coil unit with a fan motor, and there is condensed water. The disadvantages are strong blowing sensation, loud noise, no fresh air, no floor heating, troublesome maintenance and high cost. [0003] The traditional chilled beam does not have a water pan and needs to be controlled by a dew point detector. Once it is out of control, condensed water will be generated and the ceiling will be damaged. Moreover, due to the high temperature of the water supply and the small cooling capacity, the number of terminal configurations is large and the cost is high. The installation of water pipes is relatively complicated, there are many joints, there are hidden dangers of water leakage, and the dia...
