Embodiment 1

[0052] refer to figure 1 , This embodiment includes a fresh air system and an exhaust system. The fresh air system includes a casing I200, a fan I203, a first energy recovery fresh air heat exchanger 204, and a fresh air system pool 206. The casing I200 is provided with a fresh air inlet 201 and a fresh air Air supply port 217, the lower end of the casing I200 is connected to the fresh air system pool 206, the fan I203 and the first energy recovery fresh air heat exchanger 204 are installed in the casing I200 along the fresh air flow path, and the fresh air system pool 206 is provided with The water replenishment valve 207, the exhaust system includes a casing II 100, a fan II 109, a liquid distributor 108, a packed bed heat and mass exchanger 107, and an exhaust system pool 105. The casing II 100 is provided with an exhaust inlet 110 and an exhaust outlet. 112. The lower end of the shell II 100 is connected to the pool 105 of the exhaust system, the packed bed heat and mass e...

Embodiment 2

[0074] refer to figure 2 The difference between this embodiment and Embodiment 1 is that a fresh air-exhaust bypass duct 70 is arranged between the fresh air system and the exhaust system, and a fresh air-exhaust air passage 70 is arranged in the fresh air-exhaust bypass duct 70 Bypass valve 71, the inlet 208 of the fresh air-exhaust bypass duct 70 is located on the air duct behind the first energy recovery fresh air heat exchanger 204 of the fresh air system, and the outlet 106 of the fresh air-exhaust bypass duct 70 is located in the exhaust duct 70. On the air duct before the packed bed heat and mass exchanger 107 of the air system.

[0075] In hot and dry climates, by opening the fresh air-exhaust bypass ventilation valve 71, a part of the cooled fresh air can be directly entered into the exhaust system from the fresh air system, and mixed with the exhaust air from the indoor air (RA), so that the filler Evaporative cooling in the bed heat and mass exchanger 107 is bette...

Embodiment 3

[0078] refer to image 3 The difference between this embodiment and Embodiment 1 is that the fresh air system is provided with a second energy recovery fresh air heat exchanger 213, and the fresh air supply ports are two, namely the first fresh air supply port 214 and the second fresh air supply port 212, the shell is provided with an internal bypass duct 216 of the fresh air system, an internal bypass vent valve 215 of the fresh air system, and an internal connection air duct 211 of the fresh air system, and the outlet of the internal connection air duct 211 of the fresh air system is directly connected to the second fresh air supply port 212. , the outlet of the bypass duct 216 inside the fresh air system is directly connected to the first fresh air supply port 214; the surface heat exchanger 102 is arranged in the exhaust system, and the surface heat exchanger 102 is located in the thermal mass of the packed bed Before the exchanger 107, there is an internal air duct 103 of...

Abstract

A fresh air conditioning unit capable of realizing energy recovery and free cooling comprises a fresh air system and an air exhausting system, wherein a circulating pump is arranged between the fresh air system and the air exhausting system, an inlet of the circulating pump is connected with an exhausting system water pond through a pipeline, an outlet of the circulating pump is connected with an inlet of a first energy recovery fresh air heat exchanger through a pipeline, an outlet of the first energy recovery fresh air heat exchanger is connected with a liquid distributor through a pipeline to form a water or aquatic solution circulating system for realizing full heat energy recovery and free cooling circulation; and a water or aquatic solution atomizing system for humidifying the fresh air is arranged inside the fresh air system. Due to the adoption of the fresh air conditioning unit, the high-efficient energy conservation can be realized by adequately playing the effects of the energy recovery, free cooling and energy consumption reduction in a reheating process through appropriate running adjusting mechanism under different weather conditions.

Description

technical field [0001] The invention relates to a fresh air air conditioning unit, in particular to a fresh air air conditioning unit capable of realizing energy recovery and free cooling. Background technique [0002] According to the current level of air conditioning technology, if an ideal fresh air air conditioning process is to be achieved under all working conditions to meet the needs of indoor temperature and humidity control, a fresh air air conditioning unit usually not only needs to be associated with a heat pump, but also requires electric heating. With the aid of an electric heater or even an electric steam humidifier, the fresh air air conditioning process consumes a lot of energy and has low energy efficiency. [0003] In the cooling season, because the dehumidification process is also achieved through the cooling process, the heat pump needs to bear the entire cooling load of the fresh air cooling and dehumidification process in the fresh air air conditioning ...
