Abstract

The invention discloses a heat pump / heat pipe composite heating device with an adjustable working medium charging amount. The device comprises an upper header pipe, a lower header pipe, a heat pipe set, an expansion heat pipe, a valve, an upper liquid viewing mirror, a lower liquid viewing mirror, a bottom liquid viewing mirror, a condenser inlet pipe, a condenser outlet pipe and a condensate pipebundle. After a system is subjected to vacuum pumping, charging of a second refrigerant is conducted. The heat pump / heat pipe composite heating device is technically characterized in that a heat pipetype heat radiation device is driven by a condenser of a heat pump; the expansion heat pipe is an important component of a heat pipe type radiator and is internally provided with the valve and the liquid viewing mirrors, and the working medium charging amount in the expansion heat pipe can be adjusted. Adjustment of the working medium charging amount of the whole heat pipe type radiator is drivenby adjusting the working medium amount in the expansion heat pipe, and adjusting of the heat dissipation amount is achieved.

Description

technical field [0001] The invention relates to a heat pump / heat pipe composite heating device with adjustable working fluid charge, and belongs to the technical field of vapor compression refrigeration / heat pump. Background technique [0002] As a kind of energy-saving device, heat pump has been paid more and more attention, and is considered as an effective means of energy-saving and emission-reduction. Heat pumps are widely used because they can cool in summer, provide heat in winter, and are easy to operate. However, when the same fan coil unit is used for the indoor unit, the cooling is acceptable in summer, but the dry hot air is blown out during heating in winter, which reduces the comfort of people. Research has shown that the most ideal form of heating is radiant heating. [0003] The heat pump driven heat pipe type radiation cooling end is a new type of air source heat pump. Its composition type is that the condenser of the heat pump is connected with the end of...
