Embodiment 1

[0026] Example 1, see figure 1 , A dew point dehumidifier, comprising a refrigerant circulation pipe, an outdoor casing 4 and an indoor casing 6.

[0027] There are 10 refrigerant circulation pipes. The 10 refrigerant circulation pipes are the first refrigerant circulation pipe 71, the second refrigerant circulation pipe 72, the third refrigerant circulation pipe 73, the fourth refrigerant circulation pipe 74, the fifth refrigerant circulation pipe 75, the sixth refrigerant circulation pipe 76, and the The seventh refrigerant circulation pipe 77, the eighth refrigerant circulation pipe 78, the ninth refrigerant circulation pipe 79, and the tenth refrigerant circulation pipe 70.

[0028] A compressor 41 and a condenser 42 are provided in the outdoor cabinet 4. The compressor 41 is an inverter compressor. The inlet 411 of the compressor leads out of the outdoor casing 4 through the first refrigerant circulation pipe 71. A first shut-off valve 711 is provided on the first refrigera...

Embodiment 2

[0032] The second embodiment is different from the first embodiment:

[0033] See figure 2 , The condensing circulation pipe 7 is provided with a heat insulation section 7-1. The heat insulation section 7-1 on a condensing flow pipe 7 can be designed in multiple sections and distributed along the length of the condensing flow pipe. This method is used in this embodiment. The advantage of this method is that it can quickly form a vacuum negative pressure. , So that it has a good heat insulation effect even when it is frequently started and stopped; it does not need to be customized according to the length of the connecting pipe, and it can be used as a general-purpose long pipe. Of course, the heat insulation section 7-1 on a condensing flow pipe 7 can also be designed to have only one section so that its length is equivalent to that of the condensing flow pipe. The heat insulation section 7-1 includes an inner tube 7-11 and an outer tube 7-12. The inlet end of the inner tube 7...

Embodiment 3

[0044] Example three, see Figure 7 The difference from the second embodiment is that the upper deformation channel 85 and the lower deformation channel 87 are provided with end caps 80 at both ends, so that the upper deformation channel 85 and the lower deformation channel 87 both form a closed cavity. The upper inclined support plate of the upper inclined support plate 84 located between the adjacent upper deformation channels 85, the lower inclined support plate of the lower inclined support plate 86 located between the adjacent lower deformation channels 87, and the middle base plate 82 are located on the opposite side. A damping channel 88 is provided in the area between the adjacent upper deformation channel and the lower deformation channel. Both the upper deformation channel 85 and the lower deformation channel 87 are filled with damping fluid (the damping fluid is not shown in the figure). The upper deformation channel 85 and the lower deformation channel 87 are provid...

Abstract

The present invention relates to dehumidifiers. A dew point dehumidifier comprising a compressor, an evaporator, a condenser, an expansion valve, a blower directing air through said evaporator and a heat exchanger for reheating dehumidified air, an outlet of the compressor and a condenser The inlet of the condenser is connected together, the outlet of the condenser is connected with the inlet of the expansion valve, the outlet of the expansion valve is connected with the inlet of the evaporator, the outlet of the evaporator is connected with the inlet of the compressor, and the heat exchanger is equipped with A refrigerant inlet and a refrigerant outlet, the refrigerant inlet is connected to the compressor outlet, the refrigerant outlet is connected to the expansion valve inlet, and the compressor is an inverter compressor. The invention provides a dew point dehumidifier with simple structure, reliable operation and energy saving in the reheating process, which solves the problems of the existing dehumidifiers with complex systems, poor reliability, inconvenient installation and use, and high energy consumption during reheating.

Description

Technical field [0001] The invention relates to a dehumidifier, in particular to a dehumidifier that performs dehumidification by controlling the dew point. Background technique [0002] There are many structural forms of current dehumidifiers. For example, the dehumidifier disclosed in the patent documents with publication numbers CN1699855 and CN2874329: a cooling coil is installed before the evaporator, and the cooling coil is connected in series with a water-cooled condenser to pre-cool the air; the patent document with publication number CN202361532U discloses Dehumidifier: There is a pre-cooling device, a condensation dehumidifier and a blower in the air supply area. Existing dehumidifiers generally have the following shortcomings: the compressor is a fixed-speed compressor, which causes frequent uploads and downloads of the compressor and cannot be accurately controlled. Relative humidity is used for humidity control, and humidity control by relative humidity cannot trul...
