Description

Technical Field

[0001] The invention relates to the technical field of air treatment, and in particular to an energy comprehensive recovery and utilization type air treatment system. Background Art

[0002] In the summer, air conditioning systems used in areas with high outdoor temperature and humidity will generate a large amount of condensed water during operation, and consume a large amount of cooling capacity. The condensed water generated in this process is generally discharged directly. Therefore, if the sensible heat and latent heat of the condensed water can be fully utilized, it will be of great significance to reduce the energy consumption of the entire air conditioning system.

[0003] The traditional evaporative cooling method using water is generally used to cool the fresh air, which requires a large amount of fresh water. Moreover, although the temperature of the fresh air will be reduced by this treatment method, the humidity will increase. Therefore, it can only achieve better results when used in an environment with high outdoor temperature and low humidity in summer. Therefore, the scope of application of this treatment method is limited, and it requires a large amount of fresh water. Generally speaking, areas with high outdoor temperature and low humidity in summer are often areas with more serious water shortages.

[0004] Therefore, developing a new air treatment system to comprehensively recycle and utilize energy has become one of the technical problems that urgently need to be solved in this field. Summary of the invention

[0005] The purpose of the present invention is to provide an energy comprehensive recovery and utilization air treatment system and working method, which is an air treatment system that recovers energy in air conditioning condensate and DC exhaust air for energy saving and cools or heats and dehumidifies fresh air.

[0006] The present invention develops an air treatment system with the function of comprehensive energy recovery and utilization by adopting a series of methods such as collection, storage and release to the air conditioning exhaust through atomization at an appropriate time period, so that this new air treatment system can make full use of the energy contained in the air conditioning condensate, improve the energy recovery rate of the heat exchange between the air conditioning exhaust and the fresh air, effectively improve the cooling efficiency of the air conditioning refrigeration system, and thus effectively reduce the operating costs of the air conditioning refrigeration system.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is as follows:

[0010] An exhaust fan is arranged behind the air heat pipe located in the indoor exhaust processing section; an air-cooled condenser is arranged behind the exhaust fan, and the air-cooled condenser includes two groups of interfaces, one of which is connected to one interface of the four-way valve, and the other is respectively connected to the first throttle valve and the one-way valve through two parallel pipelines; the remaining three interfaces of the four-way valve are respectively connected to the inlet of the compressor, the outlet of the compressor, and the refrigerant inlet of the surface cooler in the cooling state;

[0011] The refrigerant outlet of the surface cooler in the cooling state is connected to the second throttle valve, and the second throttle valve is respectively connected to the refrigerant outlet and the one-way valve of the heat recovery reheater through two parallel pipelines; the refrigerant inlet of the heat recovery reheater is connected to the first throttle valve;

[0012] It also includes a condensed water storage tank, which is connected to an atomizing water tank via a delivery water pump, and the atomizing water tank is connected to an atomizing nozzle via an atomizing water pump.

[0013] Among them, outdoor fresh air flows in through the inlet of the outdoor fresh air treatment section and is delivered to the room through the outlet; indoor exhaust air flows in through the inlet of the indoor exhaust air treatment section, is mixed with outdoor air and then discharged through the fan of the air-cooled condenser; behind the inlet of the outdoor fresh air treatment section is a fresh air filter; behind the indoor exhaust air treatment section is an exhaust filter.

[0014] Wherein, a drip tray is provided below the surface cooler, and the drip tray is connected to the condensed water storage tank.

[0015] Among them, the atomizing nozzle includes a first atomizing nozzle, a second atomizing nozzle and a third atomizing nozzle, the first atomizing nozzle is located between the exhaust filter and the air heat pipe, the second atomizing nozzle is located between the exhaust fan and the air-cooled condenser, and the third atomizing nozzle is located at the outdoor air inlet of the air-cooled condenser.

[0016] Wherein, an air blower is provided between the fresh air filter and the air heat pipe.

[0017] Among them, a first bypass valve is provided on one side of the air heat pipe located in the outdoor fresh air processing section, a second bypass valve is provided on one side of the surface cooler, a third bypass valve is provided on one side of the heat recovery reheater, and a fourth bypass valve is provided on one side of the air heat pipe located in the indoor exhaust air processing section.

[0018] Among them, the condensed water from the energy comprehensive recovery and utilization air treatment system and other air-conditioning units flows into the condensed water storage tank, passes through the delivery water pump, and is then connected to the atomizing water tank and the condensed water inlet of other air-conditioning units respectively; the other air-conditioning units refer to air-conditioning units other than the energy comprehensive recovery and utilization air treatment system.

[0019] Among them, the water delivery pump, the atomizing water pump, the air supply fan, the exhaust fan, the air-cooled condenser, the first bypass valve, the second bypass valve, the third bypass valve, the fourth bypass valve, the first throttle valve, and the second throttle valve are all controlled by the electronic control system.

[0020] The working method of the energy comprehensive recovery and utilization air treatment system of the present invention is as follows: condensed water of air conditioning units at various locations is collected, and the indoor exhaust air of the air conditioner is cooled after atomization at a specific time period, and heat is exchanged with outdoor fresh air through an air heat pipe;

[0021] The indoor exhaust air and outdoor air after heat exchange are mixed with atomized condensed water and then enter the air-cooled condenser; when the relative humidity of the outdoor fresh air is too high and affects the indoor comfort, the heat recovery reheater can be turned on to recover the condensation heat while heating the outdoor fresh air to increase the relative humidity and ensure indoor comfort. The energy of the indoor exhaust air of the air conditioner can be effectively recovered through the air heat pipe and air-cooled condenser.

[0022] The air conditioning condensate generated in various places is collected and stored, and the collected condensate is delivered to the water tanks of various water use points including the atomizing water tank by a delivery water pump according to the liquid level of the water tanks at each water use point; the users of each water use point can monitor the changes in indoor and outdoor air through the automatic control system, and start the corresponding atomizing water pump to implement spraying during the period of higher temperature and higher electricity price during the day based on the liquid level of the condensate storage tank.

[0023] The outdoor fresh air is filtered, pressurized by the blower, and then heat exchanged with the indoor exhaust air of the air conditioner through the air heat pipe to avoid infiltration and contamination between the exhaust air and the fresh air; then it is dehumidified, cooled (in summer) or heated (in winter) by the surface cooler and then sent into the room; when the surface cooler is not working in the transition season, the bypass valve of the surface cooler can be opened to reduce the system resistance; the condensed water generated during the cooling and dehumidification process of the surface cooler is discharged to the condensed water storage tank through the drip tray for collection and utilization; in summer, when the relative humidity of the outdoor fresh air is too high, causing the indoor relative humidity to be too high and affecting the indoor comfort, the heat recovery reheater can be used to heat the fresh air, and the heating amount can be controlled by controlling the temperature of the refrigerant entering the heat recovery reheater to reduce the relative humidity of the supply air, thereby improving the indoor comfort; when the heat recovery reheater is not needed to work, the bypass valve of the heat recovery reheater can be opened to reduce the system resistance.

[0024] There will be certain impurities in the indoor exhaust air, and an exhaust filter is set to remove dust in the exhaust air; the atomizing water pump draws water from the atomizing water tank for pressurization, and then sprays it into the exhaust air purified by the filter after atomization through the first atomizing nozzle, so as to cool the exhaust air, increase the temperature difference between the fresh air and the exhaust air, and improve the heat recovery efficiency of the heat pipe; when the air heat pipe is not needed for heat exchange in the transition season, the first bypass valve and the fourth bypass valve of the heat pipe are opened to reduce the system resistance; the condensed water pressurized by the atomizing water pump is atomized through the second atomizing nozzle, and the exhaust air and the indoor air after the air heat pipe heat exchange are The outside air is mixed and enters the air-cooled condenser together to cool the high-temperature gaseous refrigerant. Since the mixed air containing atomized water has a low temperature and a high water content, the condensing temperature can be more effectively reduced under refrigeration conditions, thereby improving the efficiency of the refrigeration system and saving operating costs. Under heating conditions, the heat in the exhaust air can be recovered through heat pipes. Under heating conditions, the average air temperature of the exhaust air and the fresh air is relatively high, which can improve the efficiency of the heating system, save operating costs, and reduce the frequency of defrosting, thereby improving the comfort of the air-conditioned room.

[0025] Specifically, the following steps are included:

[0026] The condensed water generated by the surface cooler and other air-conditioning units is collected through the drip tray and stored in the condensed water storage tank, and then sent to the atomizing water tank and other water points of the air-conditioning units through the delivery water pump for buffer storage;

[0027] According to the liquid level of the condensate storage tank, during the hotter hours of the day or the higher electricity prices, the electronic control system automatically controls the atomizing water pump to pressurize the first atomizing nozzle to spray to cool the indoor exhaust air of the air conditioner and reduce the temperature of the indoor exhaust air; the cooled indoor exhaust air of the air conditioner exchanges heat with the outdoor fresh air through the air heat pipe to recover the cold in the exhaust air; the second atomizing nozzle and the third atomizing nozzle spray, and the indoor exhaust air and outdoor air that have undergone heat exchange are mixed with water mist and enter the air-cooled condenser respectively, and the high-temperature gaseous air conditioner refrigerant is condensed by using the mixed air and water mist that are lower than the outdoor ambient temperature to improve the condensation efficiency;

[0028] The air supply fan is arranged before the air heat pipe, and the exhaust fan is arranged after the air heat pipe. The outdoor fresh air processing section forms a positive pressure relative to the indoor exhaust air processing section to prevent the exhaust air from penetrating and polluting the fresh air.

[0029] When the relative humidity of outdoor fresh air is too high and affects the indoor comfort, the electronic control system adjusts the refrigerant temperature at the outlet of the air-cooled condenser so that the liquid refrigerant with a higher temperature enters the heat recovery reheater to heat the outdoor fresh air to increase the relative humidity of the outdoor fresh air. The electronic control system automatically adjusts the opening of the first throttle valve to control the heating amount of the heat recovery reheater, thereby maintaining the indoor comfort.

[0030] The upward airflow generated by the fan of the air-cooled condenser and the higher air temperature after passing through the air-cooled condenser ensure that the exhaust air discharged from the indoor exhaust air treatment section and the fresh air at the entrance of the indoor fresh air treatment section will not cross due to wind force when they are at a close horizontal distance, ensuring that the fresh air will not be polluted by the exhaust air;

[0031] In winter heating conditions, heat is exchanged with outdoor fresh air through air heat pipes to recover heat from indoor exhaust air; the flow direction of the refrigerant in the pipeline is switched through the four-way valve, so that the surface cooler is switched to the condenser and the air-cooled condenser is switched to the evaporator, thereby achieving heating of outdoor fresh air in winter conditions; the refrigerant flows directly into the evaporator through the pipeline of the one-way valve;

[0032] When the air heat pipe, the surface cooler and the heat recovery reheater are working, the corresponding first bypass valve, the second bypass valve, the third bypass valve and the fourth bypass valve are closed; when the air heat pipe, the surface cooler and the heat recovery reheater are not working (such as in the transition season), the first bypass valve, the second bypass valve, the third bypass valve and the fourth bypass valve are opened through the electronic control system to reduce the system resistance.

[0033] Compared with the prior art, the outstanding effects of the present invention are:

[0034] (1) The system of the present invention collects and stores air-conditioning condensed water generated in other places outside the system, and lowers the exhaust air temperature by atomizing the condensed water at a specific time period, thereby improving the heat exchange efficiency between exhaust air and fresh air; in summer, the air-conditioning exhaust air and the atomized condensed water at a specific time period are used to lower the cooling temperature of the air-cooled condenser, thereby improving the efficiency of the refrigeration system and saving operating costs; in winter, the air-conditioning exhaust air is used to increase the evaporation temperature of the air-cooled condenser, thereby improving the efficiency of the heating system, saving operating costs, reducing the defrosting frequency, and improving comfort; when the relative humidity of the fresh air is too high and affects the indoor comfort, the fresh air can be heated by adjusting the heating amount of the heat recovery reheater to increase the relative humidity, thereby improving the indoor comfort.

[0035] (2) The energy comprehensive recovery and utilization air treatment system of the present invention can effectively recover the energy of air conditioning exhaust, save system operation costs while ensuring indoor sanitation, improve the comfort of the air-conditioned room, and the heat recovery system is simple;

[0036] (3) The present invention makes full use of the low temperature and latent heat of vaporization of condensed water, improves the refrigeration efficiency of the air-conditioning refrigeration system, and saves operating costs;

[0037] (4) The air conditioning condensate has low hardness and no impurities. After being sprayed on the surface of the heat exchanger, it will not scale or corrode, thus reducing maintenance costs.

[0038] (5) The system does not consume fresh water, which greatly saves water resources.

[0039] The energy comprehensive recovery and utilization air treatment system and working method of the present invention will be further described below in conjunction with specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

The upward airflow generated by the fan of the air-cooled condenser and the higher air temperature after passing through the air-cooled condenser ensure that the exhaust air discharged from the indoor exhaust air treatment section and the fresh air at the entrance of the indoor fresh air treatment section will not cross due to wind force when they are at a close horizontal distance, ensuring that the fresh air will not be polluted by the exhaust air; In winter heating conditions, heat is exchanged with outdoor fresh air through air heat pipes to recover heat from indoor exhaust air; the flow direction of the refrigerant in the pipeline is switched through the four-way valve, so that the surface cooler is switched to the condenser and the air-cooled condenser is switched to the evaporator, thereby achieving heating of outdoor fresh air in winter conditions; the refrigerant flows directly into the evaporator through the pipeline of the one-way valve; When the air heat pipe, the surface cooler and the heat recovery reheater are working, the corresponding first bypass valve, the second bypass valve, the third bypass valve and the fourth bypass valve are closed; when the air heat pipe, the surface cooler and the heat recovery reheater are not working, the first bypass valve, the second bypass valve, the third bypass valve and the fourth bypass valve are opened through the electronic control system to reduce the system resistance.
