Heat recovery type full fresh air cooled dehumidifier

Abstract

The invention provides a heat recovery type full fresh air cooled dehumidifier. In the dehumidifier, an indoor unit of the full fresh air cooled dehumidifier is arranged indoors, and is connected with a heat recovery heat exchanger; the top end of the heat recovery heat exchanger is connected to the outdoors through a first air pipe (i); the air outlet of the first air pipe (i) is provided with an exhaust fan; the side wall of the first air pipe (i) and an air pipe port which are close to the exhaust fan indoors are provided with a first air valve (i) and a second air valve (ii) respectively; a third air valve (iii) is arranged on the first air pipe (i) between the second air valve (ii) and the heat recovery heat exchanger; the third air valve (iii) is arranged outdoors; and the lower end of the heat recovery heat exchanger is connected with the draught fan of the outdoor unit of the full fresh air cooled dehumidifier through a second air pipe (ii). The dehumidifier has the beneficial effects of realizing high cooling efficiency, low energy consumption, stable operation and long service life of the full fresh air cooled dehumidifier, and realizing heat recycle.

Description

technical field [0001] The invention relates to a dehumidifier, in particular to a heat recovery type fresh air air-cooled dehumidifier. Background technique [0002] When the fresh air air-cooled dehumidifier is running, the unit introduces fresh air from the outside. In order to balance the indoor pressure, it discharges the indoor air with a corresponding air volume. The condensation heat is exchanged with the atmosphere by the condenser of the outdoor unit, and the heat is dissipated in the atmosphere. When this kind of unit is running, the refrigeration efficiency is low and the energy consumption is high. Especially when the outdoor temperature is low, the operation is unstable, which affects the life of the unit and wastes condensation heat. Contents of the invention [0003] The purpose of the present invention is to provide a heat recovery type all-new air-cooled dehumidifier, which overcomes the low cooling efficiency and high energy consumption of the existing a...
