The invention discloses a deicing system with hot-press diaphragm sac ducts for overhead fans of a heat-pump-type bus air conditioner. The deicing system comprises a bus body and a vehicle-mounted battery, wherein an air intake pipe and air-conditioning fans are arranged on an outside heat exchanger, a hot-press diaphragm sac tail gas channel is arranged on the outer side of an annular cavity of each air-conditioning fan, and a tail gas intake opening is formed in the lower part of each annular cavity; an exhaust manifold is arranged at the lower part of the bus body and communicates with a bypass pipe through a three-way valve, the bypass pipe communicates with the hot-press diaphragm sac tail gas channels, and the hot-press diaphragm sac tail gas channels communicate with the corresponding annular cavities through the corresponding tail gas intake openings; and an energy storage bag is arranged at each tail gas intake opening, and arranged in an energy storage bag pipeline of each tail gas intake opening, and an electric heater plug is electrically connected with the vehicle-mounted battery and clamped on the outer wall of the energy storage bag pipeline. By adoption of the technical scheme, the operating environment of the outside heat exchanger is improved to ensure normal heating, so that the efficiency of a bus air-conditioning heat pump system at low temperature is improved.
Description
technical field [0001] The invention relates to a deicing system, in particular to a winter deicing or defrosting system for a passenger car air conditioner overhead fan with a hot-pressed membrane air bag tube heat pump. Background technique [0002] Energy issues have become a hot topic in today's society. However, about 30%-40% of the energy in the exhaust gas of passenger cars is discharged into the atmosphere in the form of exhaust heat, which has attracted much attention. How to efficiently use exhaust heat has become a key to saving energy. The key is to reduce the emission of pollutant particles at the same time. With the development of passenger car technology, the heat pump technology for passenger cars has the characteristics of energy saving and environmental protection. However, its heating operation in winter is faced with a serious problem. The surface of the evaporator on the outside of the car is prone to frost. The static pressure of the fan at the evapora...
