Description
Technical Field
The invention relates to an air conditioning system, in particular to a re-adsorption energy storage type air conditioning system and a control method thereof.
Background
With the shortage of fossil energy such as petroleum and the serious problems of air pollution, electric automobiles are receiving more and more attention as substitutes for common gasoline vehicles. However, the electric vehicle has disadvantages of short running distance and high finished battery. The air conditioner applied to the electric automobile at present is a compression type air conditioner directly driven by an automobile battery. The traditional compression type air conditioner can consume 30-50% of energy of an electric automobile, and the running mileage is reduced by 40-60%, so that not only is the extra burden of an automobile battery caused, but also the problem of short running distance of the electric automobile is aggravated. One way to solve this problem is to separate the electricity consumption process from the air conditioning process, which would solve the problem of short running distance of the electric vehicle to a great extent and increase its development potential. The process can not be realized by depending on the traditional compression type air conditioner, but depends on the green environment-friendly re-adsorption technology, thereby providing possibility for practical application of the process. The re-adsorption system mainly comprises a high-temperature adsorption bed, a low-temperature adsorption bed, a connecting valve and a pipeline. Different from the adsorption system, the reabsorption system has no flowing liquid ammonia, so that the safety is higher, and the system is more suitable for long-distance transportation working conditions. The re-adsorption system operation generally includes two processes: (1) a desorption process of the high temperature bed, in which the high temperature adsorption bed is heated by an electric heater, and the low temperature adsorption bed is cooled by air, so that the refrigerant in the high temperature adsorption bed is desorbed and flows to the low temperature adsorption bed to be adsorbed therein; (2) in the desorption process of the low-temperature bed, the high-temperature adsorption bed is cooled by air, so that the refrigerant is desorbed from the low-temperature adsorption bed into the high-temperature adsorption bed. The desorption process of the low-temperature adsorption bed and the adsorption process of the high-temperature adsorption bed can respectively generate cold and heat for refrigeration in summer and heat supply in winter.
An analysis of MnCl was performed by a target-oriented inductive-gas thermal absorption boiler for an integrated energy storage and energy anode2-CaCl2-NH3The potential for high energy storage density of the re-adsorption cycle. Banhanshan et al (resource system for cooling and long-distance regeneration) have established a re-adsorption system for cold-storage long-distance operation air-conditioning, and the results show that the coefficient of performance (coefficient of performance-COP) can reach 0.20 to 0.31 under different operation conditions. The inventor of the invention previously researches the performance analysis of direct heat supply and simultaneous heat supply and refrigeration by utilizing a re-adsorption system, and the experimental result shows that the maximum energy storage density can reach 1706kJ/kg, and the maximum average refrigeration power reached in the refrigeration process is 1.07 kW.
However, to date, there has been no research work to analyze the feasibility of applying a re-adsorption cycle to an air conditioner for an electric vehicle.

In order to facilitate understanding of the embodiments of the present invention, the following will be further explained by taking specific embodiments as examples, and each embodiment is not to be construed as limiting the embodiments of the present invention.
In summer, the ambient temperature is often higher than 30 ℃, so the cooling air temperature is selected to be 35 ℃. The cooling temperature in the electric vehicle is selected to be 5 degrees. When the electric automobile does not run at night, the electric heater connected with the mains supply heats the high-temperature adsorption bed, the heating temperature can reach 200 ℃, but the highest heating temperature is lower than 180 ℃ in consideration of safety limitation.
In winter, the ambient temperature is around 10 ℃, and the desorption/adsorption temperature of the cryoadsorption bed is selected as the ambient temperature. When the high temperature adsorbent reaches its equilibrium adsorption/desorption point in the winter season, adsorption/desorption reactions occur in the high temperature adsorbent bed. The maximum desorption temperature of the high temperature adsorption bed is specified to be 180 deg.c, and the minimum adsorption temperature thereof should be higher than 25 deg.c (which is the control temperature of the air in the electric vehicle cabin).
Therefore, taking 35 ℃ in summer and 10 ℃ in winter as examples, the working performance of the embodiment is as follows:
(1) in summer and at night, the ammonium chloride composite adsorbent, i.e., the ammonium chloride composite adsorbent preferably in the packed portion, is located at the initial state of the second adsorption bed 12, and the minimum adsorption amount, for example, 0.32kg of NH is observed3/kg NH4Cl, cooled by a 35 ℃ air source to perform the isothermal adsorption process. Meanwhile, the manganese chloride composite adsorbent is preferably ammonium chloride composite adsorbent in the filling part, and the first adsorption bed 11 in which the manganese chloride composite adsorbent is located is heated by the electric heater 14 to carry out a temperature rise desorption process. During the daytime, the temperature of the second adsorption bed 12 is controlled to a refrigeration temperature of 5 ℃, and the first adsorption bed 11 is cooled by the outside air maintained at 35 ℃, so that the refrigerant ammonia is desorbed from the second adsorption bed 12 into the first adsorption bed 11. The heat of desorption from the second adsorption bed 12 provides a refrigeration effect. In this process, the circulating adsorption amount of the ammonium chloride composite adsorbent in the second adsorption bed 12 is preferably 0.63kg of NH3/kgNH4Cl, and the circulating adsorption amount of the adsorbent in the first adsorption bed 11 is preferably 0.21kg NH3/kg MnCl2. The theoretical COP and the energy storage density are 0.38 and 803kJ/kg, respectively.
(2) In winter, when the ambient temperature is 10 ℃ and the heating temperature in the electric vehicle cabin is controlled to be 25 ℃, the following working conditions are provided. At night, the second adsorption bed 12 with the ammonium chloride composite adsorbent is cooled by a 10 ℃ air sourceAfter cooling, an isothermal adsorption process is performed. Meanwhile, the first adsorption bed 11 where the manganese chloride composite adsorbent is located is heated by the electric heater 14, and a temperature rise desorption process is carried out. During the daytime, the temperature of the second adsorption bed 12 is still controlled at 10 ℃ in heat exchange with the outside air, and the adsorption temperature of the first adsorption bed 11 is maintained at 25 ℃, so that the refrigerant ammonia is desorbed from the second adsorption bed 12 into the first adsorption bed 11. The heat of adsorption of the first adsorption bed 11 provides a heating effect. In this process, the circulating adsorption amount of the ammonium chloride composite adsorbent in the second adsorption bed 12 is preferably 0.63kg of NH3/kg NH4Cl, the circulating adsorption amount of the adsorbent in the first adsorption bed 11 is preferably 0.23kgNH3/kg MnCl2. The theoretical COP and the storage density were 0.69 and 1445kJ/kg, respectively.
