<p>A method for increasing heating temperature of a heat pump and a high temperature second-type absorption heat pump are disclosed. An additional flash evaporator (1), an additional absorber (2), an additional throttle valve (6), an additional solution pump (3) and an additional solution heat exchanger (5) are added to a low temperature second-type absorption heat pump, thereby arriving at the high temperature second-type absorption heat pump. An absorber (D1) is orderly communicated with the additional flash evaporator (1) and the additional absorber (2) through a concentrated solution pipeline, the additional absorber (2) is communicated with the absorber (D1) through a dilute solution pipeline; a condenser (B1) is orderly communicated with the absorber (D1) and the additional absorber (2) through a coolant medium pipeline, the additional flash evaporator (1) is communicated with the condenser (B1) through a coolant steam pipeline, and the additional absorber (2) is communicated with the external through a heated medium pipeline.</p> |
