The utility model relates to a module Type air-exhausted heat pump unit and a method for recovering waste heat from mine ventilation, which comprises a casing structure unit of the unit, a heat pump thermodynamic system unit, a cleaning unit of the mine ventilation heat exchanger and a power distribution control unit, the heat pump thermal system unit includes at least one set of heat pump mechanism, water? Water? Water? Water? Water? Water? Water? Water? The working medium heat exchanger is provided with a water exchange inlet and a water exchange outlet. The cleaning unit of the mine exhaust heat exchanger comprises a cleaning pressurizing pump, a cleaning solenoid valve and a one-way valve, the cleaning fluid main pipe is connected with a fan-shaped nozzle arranged on the air inlet side of the mine exhaust heat exchanger through the cleaning distribution pipe. The present split-type compression condensing unit and the direct evaporating heat extractor are combined into a whole, greatly reducing the project installation cost and the unit commissioning cost, and can meet various installation directions of the coal mine lack-air heat pump, at the same time increased the function of automatic cleaning.
