Embodiment 1

[0022] like 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 re...

Embodiment 2

[0030] like 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] like 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 and heat pipe composite heat supply device capable of mutually adjusting working medium filling quantities. The heat pump and heat pipe composite heat supply devicecomprises a compressor, a heat pipe type radiator, a high-pressure liquid storage device, a throttling valve, a low-pressure liquid storage device, an evaporator, a 1# valve, a 2# valve and a 3# valve; and a heat pump condenser and the heat pipe type radiator are combined together, and heat of the heat pump condenser is emitted through a heat pipe. The heat pump and heat pipe composite heat supply device has the technical characteristics that pipelines and the valves are connected among the heat pipe type radiator, the high-pressure liquid storage device and the low-pressure liquid storage device, and different positions of the heat pipe type radiator are provided with three sight glasses jointly; and by adjusting the valves, the heat pipe working medium filling quantity and the heat pumpworking medium filling quantity are mutually adjusted, thus a working medium in a heat pump or the heat pipe is recovered, or the heat dissipating capacity of the heat pipe radiator is adjusted.

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...
