Embodiment 1

[0022] Such as figure 1 As shown, a heat pump / heat pipe composite heat supply device with mutually adjustable working fluid charge is characterized in that the device includes a compressor (1), a heat pipe radiator (2), a high-pressure liquid accumulator (3) , throttle valve (4), low-pressure liquid reservoir (5), evaporator (6), 1# valve (7), 2# valve (8), 3# valve (9), 1# sight glass (10 ), 2# sight glass (11) and 3# sight glass (12). The heat pump system and the heat pipe radiator are filled with the same working fluid. The outlet of the compressor (1) is connected to the inlet of the heat pipe radiator (2); the outlet of the heat pipe radiator (2) is connected to the inlet of the high-pressure liquid reservoir (3), and the outlet of the high-pressure reservoir (3) is connected to The inlet of the throttle valve (4) is connected, the outlet of the throttle valve (4) is connected with the inlet of the low-pressure liquid reservoir (5), the outlet of the low-pressure liquid...

Embodiment 2

[0030] Such as Figure 2-3 As shown, a heat pump / heat pipe composite heating device with mutually adjustable working fluid charge, and a structural schematic diagram of a heat pipe radiator. The condenser of the heat pump, that is, the condensing coil is inserted into the bottom of the heat pipe radiator and welded together in isolation from each other. The 1# sight glass, the 2# sight glass and the 3# sight glass can respectively observe the filling amount of the working fluid in the heat pipe radiator at different heights.

[0031] Such as Figure 4 As shown, a heat pump / heat pipe composite heating device with mutually adjustable working fluid charge, and a schematic diagram of the system structure with two heat pipe radiators. The pipeline connection of the two heat pipe radiators is the same as that of a single heat pipe radiator, both of which are connected to the high-pressure liquid reservoir and the low-pressure liquid reservoir through valves.

Abstract

The invention discloses a heat pump / heat pipe composite heat supply device with mutual adjustment of working medium charging amount, the device includes a compressor, a heat pipe radiator, a high-pressure liquid storage device, a throttle valve, a low-pressure liquid storage device, and an evaporator , 1# valve, 2# valve and 3# valve. The condenser of the heat pump is combined with the heat pipe radiator, and the heat of the heat pump condenser is dissipated through the heat pipe. The technical feature of the present invention is that pipelines and valves are connected between the heat pipe radiator, the high-pressure liquid reservoir and the low-pressure liquid reservoir, and three sight glasses are installed at different positions on the heat pipe radiator. By adjusting the valve, the mutual adjustment of the working fluid charge of the heat pipe and the heat pump is realized, thereby realizing the recovery of the working medium in the heat pump or the heat pipe, or adjusting the heat dissipation of the heat pipe radiator.

Description

technical field [0001] The invention relates to a heat pump / heat pipe composite heat supply device with mutually adjustable working fluid charge, which 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 cooling device is a new type of air source heat pump. Its composition type is that the condenser of the heat pump is combined with the...
