The invention provides a central air conditioning system. The central air conditioning system comprises an air return pipe communicated with an indoor air return port, an outdoor unit, and an air outlet pipe connected with the outdoor unit, wherein the tail end of one of the air return pipe and the air outlet pipe is embedded into the other one; and the air return pipe is communicated with the air outlet pipe. The central air conditioning system, provided by the invention, uses the negative pressure in an air outlet of the air outlet pipe of the outdoor unit for generating the pressure difference between indoor pressure and outdoor pressure, and realizes the air return under the effect of the pressure difference, so that the operation time and the operation frequency of air returners are reduced, the air return energy consumption is reduced, and the energy consumption of the central air conditioning system is reduced; and meanwhile, the air returners can be reduced, parts of the central air conditioning system are reduced, and the equipment cost of the central air conditioning system is reduced.
Description
technical field [0001] The invention relates to the technical field of central air-conditioning energy saving, and more specifically relates to a central air-conditioning system. Background technique [0002] Central air-conditioning has the advantages of economy, energy saving, environmental protection, and long service life, and is widely used. [0003] For the outdoor unit of the central air-conditioning system, the required installation space is relatively large. However, the installation space of the outdoor unit of the household air conditioner is relatively narrow or the three sides are sealed by the enclosure structure. At this time, an air duct needs to be installed at the air outlet of the outdoor unit to lead the exhaust air of the outdoor unit to the outside, so as to ensure the central air conditioning system. of normal operation. At the same time, the indoor return air also needs to be equipped with a return air duct to lead the return air out. [0004] At p...
