Abstract

The invention discloses an air conditioner six-way valve and a heat-pump-type air conditioner comprising the same. The air conditioner six-way valve comprises a main valve and a guide valve; the mainvalve is connected with the guide valve through a pipeline; the main valve comprises a main valve shell, a main valve sliding block, a main valve left-side spring, a main valve right-side spring and six valve ports; the guide valve comprises a guide valve shell, a guide valve sliding block, a left-end controller, a right-end controller and four guide valve ports; the heat-pump-type air conditionercomprises the air conditioner six-way valve, a compressor, a first outdoor heat exchanger, a second outdoor heat exchanger, an indoor heat exchanger, an electronic expansion valve, a throttling controller and a pipeline selector. By adopting the air conditioner six-way valve, switching of a left state, a middle state and a right state can be realized; an ordinary air conditioner four-way valve can be replaced; the air conditioner can switch among a refrigeration mode, a heating mode and three defrosting modes; and the heat-pump-type air conditioner comprising the air conditioner six-way valvecan heat indoors and operate in a defrosting mode outdoors at the same time in winter, so that indoor comfortability is improved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment, in particular to an air-conditioning six-way valve and a heat pump air conditioner containing it. Background technique [0002] With the continuous improvement of people's living standards, the use of air conditioners has become quite common, but the frosting problem of heat pump air conditioners restricts its effective operation when the temperature is low and the humidity is high. In winter in high-humidity areas, when the heat pump is heating the room, the cold energy will be discharged into the air through the outdoor heat exchanger. If the surface temperature of the outdoor heat exchanger is lower than 0°C (under standard atmospheric pressure), water vapor in the air will easily Frost forms on the surface of the outdoor heat exchanger, which increases the heat transfer resistance. If it is not treated in time, the gap between the fins of the outdoor heat exchanger will gr...
