Description

Technical Field

[0001] The present application relates to the technical field of air treatment, and specifically discloses a heat recovery evaporation and condensation integrated dehumidification device. Background Art

[0002] With the development of society and the improvement of people's living standards, people have higher and higher requirements for their living environment. Among them, the parameter of air humidity is one of the factors that people pay close attention to.

[0003] In order to control the air humidity in the indoor environment and achieve dehumidification, most of the indoor environment is ventilated at present. Ventilation is to introduce dry fresh air from the outside to discharge the humid air in the room, thereby reducing the humidity and achieving the purpose of dehumidification. However, although the existing ventilation and dehumidification methods have low energy consumption, the outdoor fresh air is not dry most of the time, especially in areas that are already in humid areas. The use of ventilation is not only easy to discharge more humid air into the room without dehumidification, but also aggravates the situation of excessive humidity in the indoor environment, which is inefficient. Therefore, in view of this, the inventor provides a heat recovery evaporation and condensation integrated dehumidification device to solve the above problems. Utility Model Content

[0004] The utility model aims to solve the problem that the traditional indoor environment adopts ventilation to dehumidify the environment, which not only easily discharges more humid air into the room, but also aggravates the over-humidity of the indoor environment and has low efficiency.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a heat recovery evaporation and condensation integrated dehumidification device, including a support base, an evaporator for absorbing heat in humid air is installed at one end of the support base, one end of the evaporator is connected to an air suction piece for sucking humid air into the evaporator, the evaporator is installed with a refrigerant for cooling and condensing the sucked air, the other end of the support base is installed with a condenser for releasing the heat absorbed in the evaporator, the evaporator is also connected to a compressor refrigeration system for driving the refrigerant to circulate between the evaporator and the condenser, a condensation drain pipe is provided at the bottom of the evaporator, and a heat recovery system for absorbing the heat dissipated by the refrigerant and heating the indoor air is provided between the evaporator and the condenser.

[0006] The principles and effects of this basic solution are:

[0007] 1. Compared with the prior art, the utility model realizes the cooling and dehumidification of humid air by arranging an evaporator, a compressor refrigeration system and a condenser, collects and inhales the humid air by arranging an air suction piece, and improves the efficiency of the dehumidification work. By arranging a heat recovery system, the heat absorbed from the humid air by the refrigerant when cooling the humid air is recovered, and the heat is passed into the indoor air for use, so as to heat the dry air in the room after the dehumidification treatment, thereby further dehumidifying and evaporating the indoor air, greatly improving the dehumidification efficiency. Under the circulating operation of the overall device, the air in the humid room is made more comfortable and no longer humid, solving the problem that the traditional indoor environment uses ventilation to dehumidify the environment, which not only easily discharges more humid air into the room, but also aggravates the situation of excessive humidity in the indoor environment and the problem of low efficiency.

[0008] Furthermore, the compressor refrigeration system includes a compressor for compressing the refrigerant into a high-temperature and high-pressure gas and an expansion valve for gradually releasing the refrigerant into the evaporator, the compressor is installed between the evaporator and the condenser, and the expansion valve is installed on the compressor. By providing the compressor and the expansion valve, it is convenient to adjust and change the state of the refrigerant, so that the refrigerant absorbs and releases heat to the air, so that the air can be condensed and dehydrated more quickly and conveniently.

[0009] Furthermore, the air suction member includes a fan for sucking moist air and a ventilation duct connected between the fan and the inlet end of the evaporator. By arranging the fan and the ventilation duct, the moist air is sucked into the evaporator for dehumidification, so that the overall dehumidification efficiency is higher.

[0010] Furthermore, a plurality of mounting bases are evenly arranged at the bottom of the evaporator, and the mounting bases are detachably connected to the support base, and a water collection pan connected to the condensation drainage pipe is arranged at the bottom of the evaporator.

[0011] Furthermore, the mounting base includes a fixed base and a mounting plate detachably connected to the top of the fixed base, and one end of the mounting plate away from the fixed base is detachably connected to the bottom of the evaporator. The fixed base is a truncated cone-shaped structure, and a plurality of limiting convex rings for supporting the mounting plate are longitudinally fixed on the peripheral side of the fixed base, and the mounting plate is sleeved on the limiting convex rings. By providing the fixed base and the mounting plate, it is convenient to provide structural support for the bottom of the evaporator, improve the stability of the structure, and also facilitate the installation of the water pan. By providing the limiting convex ring, it is convenient to limit the installation position of the mounting plate, thereby facilitating the adjustment of the installation height of the evaporator.

[0012] Furthermore, the heat recovery system includes a heat pipe precooling section for precooling the humid air to precipitate condensed water and a heat pipe reheating section for heating the dehumidified and cooled air, and both the heat pipe precooling section and the heat pipe reheating section are installed between the evaporator and the condenser.

[0019] A heat recovery evaporation condensation integrated dehumidification device, for example Figure 1 and Figure 2As shown: it includes a support base 1, an evaporator 2 for absorbing heat in humid air is installed at the front end of the support base 1, an air suction piece for sucking humid air into the evaporator 2 is connected to the front end of the evaporator 2, a refrigerant for cooling and condensing the sucked air is installed in the evaporator 2, a condenser 3 for releasing the heat absorbed in the evaporator 2 is installed at the rear end of the support base 1, the evaporator 2 is also connected to a compressor 4 refrigeration system for driving the refrigerant to circulate between the evaporator 2 and the condenser 3, a condensation drain pipe is provided at the bottom of the evaporator 2, and a heat recovery system for absorbing heat dissipated by the refrigerant and heating the indoor air is provided between the evaporator 2 and the condenser 3.

[0020] Among them, Figure 1 and Figure 2 As shown, the compressor 4 refrigeration system includes a compressor 4 for compressing the refrigerant into a high-temperature and high-pressure gas and an expansion valve for gradually releasing the refrigerant into the evaporator 2.

[0021] Among them, Figure 1 As shown, three mounting bases 7 are evenly arranged at the bottom of the evaporator 2, and the mounting bases 7 are detachably connected to the support base 1. A water collection pan connected to the condensation drain pipe is arranged at the bottom of the evaporator 2. Figure 3 As shown, the mounting base 7 includes a fixed base and a mounting plate 8 detachably connected to the top of the fixed base, the end of the mounting plate 8 away from the fixed base is detachably connected to the bottom of the evaporator 2, the fixed base is a truncated cone-shaped structure, and four limiting convex rings 9 for supporting the mounting plate 8 are longitudinally equidistantly fixed on the circumference of the fixed base, and the mounting plate 8 is mounted on the limiting convex ring 9 located at the top of the fixed base.

[0022] Among them, Figure 1 As shown, the heat recovery system includes a heat pipe precooling section 10 for precooling humid air to precipitate condensed water and a heat pipe reheating section 5 for heating the dehumidified and cooled air, and the heat pipe precooling section 10 and the heat pipe reheating section 5 are both installed between the evaporator 2 and the condenser 3.
