Description

Technical Field

[0001] The utility model relates to a cooling type air conditioner and belongs to the technical field of fresh air systems. Background Art

[0002] Building energy consumption accounts for about 1 / 3 of the total energy consumption, among which air conditioning energy consumption accounts for about 50% of the building energy consumption. Among them, for the fresh air air-conditioning system, the fresh air load is the main component of the air-conditioning load. How to reduce the fresh air air-conditioning load is of great significance to achieving energy conservation, environmental protection and low-carbon emission reduction.

[0003] Among them, evaporative cooling uses dry air energy as a driving force to achieve the effect of cooling through water evaporation. It is an energy-saving, environmentally friendly, economical and healthy technology. As an application of evaporative cooling technology, the vertical indirect evaporative cooler usually uses secondary air indoor exhaust and spray water to flow in the coil, and conducts the cold to the primary air outdoor fresh air outside the tube through the tube wall. The primary air is sent indoors after dehumidification and cooling to establish a comfortable and constant temperature environment indoors. However, the cooling limit of indirect evaporation will not be lower than the wet-bulb temperature of the secondary air. When the outdoor temperature is high, the indirect evaporative cooler alone cannot meet the indoor temperature requirements. Therefore, it is particularly important to find a low-cost and high-efficiency method to cool and dehumidify the fresh air.

[0004] Therefore, it is urgent to propose an evaporative cooling air conditioner with dehumidification function to solve the above technical problems. Utility Model Content

The first fan 2-5 is fixedly connected to the outer shell 2-9. The outer shell 2-9 at the corresponding position of the filler 2-6 has a vent. The output end of the first fan 2-5 is arranged corresponding to the filler 2-6. The water outlet of the water collecting tray 2-4 is connected to the spray device 2-3 through the circulating pump 2-2. The spray device 2-3 adopts a pipe with holes. The heat exchange core 2-1 adopts an S-shaped heat dissipation pipe. The circulating cooling water of the heat exchange core 2-1 The inlet 2-7, the cooling circulation system of the refrigeration device 3, the cooling water pump 8, and the circulating cooling water outlet 2-8 of the heat exchange core 2-1 are connected in a circular manner, the hot water circulation system of the refrigeration device 3, the hot water pump 9, and the hot water tank 4 are connected in a circular manner, the chilled water circulation system of the refrigeration device 3, the first chilled water pump 10, and the chilled water tank 5 are connected in a circular manner, and the chilled water tank 5, the second chilled water pump 11, and the pipe process of the heat exchanger 6 are connected in a circular manner; in the utility model, the hot water required for the desorption process is prepared by heating the circulating water in the hot water tank with industrial waste heat. The industrial waste heat is a free heat source, and direct discharge may cause thermal pollution. Therefore, it can reduce or avoid harm to the environment by preparing hot water before discharging it; and the cooling water required for the adsorption process of the adsorption refrigeration device is Figure 4 The vertical closed cooling tower provides, through evaporative cooling, the circulating cooling water temperature reaches the requirements of the adsorption refrigeration device;

[0032] The function of the vertical closed cooling tower is to cool down and dissipate the circulating cooling water in the adsorption refrigeration device 3, wherein the circulating cooling water enters the heat exchange core 2-1 through the circulating cooling water inlet 2-7, and after being cooled, it is re-supplied to the adsorption refrigeration device 3 from the circulating cooling water outlet 2-8 for use; in addition, in the vertical closed cooling tower, the spray water in the water collecting tray 2-4 at the bottom of the tower is driven by the circulating water pump 2-2 and flows to the spray system 2-3 at the top of the tower. Through the action of the spray system 2-3, the spray water evenly covers the surface of the heat exchange core 2-1 and exchanges heat with the circulating cooling water in the heat exchange core 2-1. After absorbing heat, the spray water continues to flow downward by its own gravity, and exchanges heat with the air driven by the fan 2-5 in the filler 2-6. Finally, the air takes away the heat, and the spray water is cooled and gathered in the bottom water collecting tray 2-4 to complete a cycle; the advantages of the vertical closed cooling tower are Through the action of the spray system 2-3, the spray water is evenly sprayed on the outer surface of the heat exchange core 2-1, and the air and the spray water flow downward in the same direction. With the help of the wind, the spray water can be more evenly distributed on the outer surface of the heat exchange unit, and the heat exchange effect is better than that of an ordinary closed cooling tower. The utility model has the characteristics of greatly improving the performance coefficient of the unit, being applicable to a large number of high-temperature and high-humidity areas, avoiding excessive noise, and reducing the energy consumption of the fan. The combination of a vertical closed cooling tower, a vertical indirect evaporative cooler and a vertical high-efficiency heat exchanger further improves the energy utilization efficiency, enhances the dehumidification and cooling effect, and significantly improves the indoor air quality. By using an adsorption refrigeration device, free industrial waste heat is utilized as a hot water preparation energy source, realizing the recycling of waste heat while protecting the environment. In addition, the condensed water generated after the fresh air is dehumidified can be collected for use as spray water replenishment for the vertical closed cooling tower, thereby achieving a water-saving effect.

[0033] The hot water tank 4 is provided with a coil, and industrial waste heat is introduced into the coil to heat the liquid in the hot water tank 4, thereby saving the huge electric energy consumed by the adsorption refrigeration device 3 for preparing hot water. The free industrial waste heat is used to heat the hot water. In the process of cooling and dehumidifying the fresh air, only a few water pumps and fans consume electricity, which realizes energy recovery and reduces thermal pollution to the environment. The working process of the adsorption refrigeration device mainly includes two processes: desorption and adsorption. Among them, desorption requires hot water, and adsorption requires cooling water.

[0035] The primary air inlet header 1-7 is located below the primary air outlet header 1-8; the primary air (i.e., outdoor fresh air) enters the heat exchange core 1-1 through the primary air inlet header 1-7, flows from bottom to top, exchanges energy with the spray water located outside the heat exchange unit, and is finally sent to the room or other air treatment equipment through the primary air outlet header 1-8. The primary air and the spray water flow in countercurrent, which can ensure that the primary air is cooled to a maximum temperature.

[0036] In autumn and winter, cooler 1 is the main equipment for fresh air treatment. It pre-treats outdoor fresh air (primary air). Through the energy exchange effect of secondary air and spray water, the fresh air temperature can be reduced to a certain value (the limit temperature is the wet-bulb temperature of secondary air). In autumn and winter, the indoor environment can basically meet the temperature and humidity requirements of fresh air.

[0037] In high temperature and high humidity areas in summer, this specific embodiment adopts a refrigeration device 3 to prepare chilled water for cooling and dehumidifying fresh air. The refrigeration device 3 is composed of three major parts: a cooling circulation system, a hot water circulation system and a chilled water circulation system.
