Description
Technical Field
The utility model relates to an air condensing units defrost system of integrated vortex tube and semiconductor refrigeration piece belongs to the air conditioner and maintains the field.
Background
In recent years, with the continuous development of national economy of China and the continuous improvement of living standard of people, air conditioners enter thousands of households. In the south of China, heating is not popularized yet, and an air conditioner is still necessary equipment for the family to pass winter. However, when the ambient temperature is low, the air conditioner heating is difficult to operate, and even if it is operated, the effect is poor, and the lower the temperature is, the more frosting is likely to occur. This is because the air conditioner mainly performs a heating operation during operation in winter, and is in an evaporation and heat absorption state outdoors, and if the outdoor temperature is low during the use of the air conditioner, the evaporation temperature of the heat exchanger of the air conditioner outdoor unit is lower than zero, and moisture in the air is condensed into frost on the air conditioner outdoor unit. The frosting of the air conditioner can seriously affect the heating operation of the air conditioner, directly cause the shutdown of the air conditioner, and generally cause the operation of the air conditioner to consume more electric energy and the heating effect to be poor. How to effectively solve the problem of frosting of the air conditioner external unit causes more and more people to pay attention, and the problem of frosting of the air conditioner external unit by utilizing external heat energy becomes a research direction of the household air conditioning industry.
At present, the frosting of an air conditioner external unit is the main reason influencing the heating of an air conditioner in winter, and the self defrosting of an air conditioning system is the current main mode, which is that the defrosting is controlled by a defrosting scheme set by an air conditioner manufacturer. Generally, the outdoor temperature is about 5 ℃, the air conditioner can defrost normally, and the normal operation of the air conditioner is not affected, but when the outdoor temperature is too low, the defrosting function of the air conditioner is difficult to use effectively. When the temperature is too low, manual defrosting is an effective mode, hot water is used for flushing an air conditioner external unit, or the air conditioner external unit is knocked off to break ice to achieve a defrosting function, but the difficulty coefficient is high, and the practice is inconvenient. In addition, the air conditioner can be adjusted to a refrigeration mode for defrosting, and the method is only suitable for the outdoor unit with serious frosting, the air conditioner is difficult to operate, and the method is not suitable for the household daily air conditioner defrosting. The external heat source is used for defrosting, so that the normal operation of the air conditioner can be ensured in extreme weather, and partial scholars propose to defrost by externally connecting the heat source to an air conditioner external unit. For example, patent 201611160266.8 is used for a vortex tube defrosting system of a heat pump type passenger car air conditioning system, hot air generated by a vortex tube is sprayed to the outer surface of an evaporator through a hot channel, a control valve and a hot air flow nozzle, so that the problems that the system cannot normally heat when the outdoor temperature of the heat pump type passenger car air conditioning system is low in winter, frequent defrosting and incomplete defrosting of an air conditioner are solved, but the working characteristic that the vortex tube can separate cold and hot air flows is not fully utilized, and the waste of resources is caused; for example, patent 201210267469.2 discloses that the problem of frosting of the air conditioner external unit is solved by spraying hot water, but defrosting by spraying hot water is not only energy-consuming and inefficient, but also easily causes water pollution.
The utility model discloses combine vortex tube and semiconductor refrigeration piece two kinds and air conditioning system, when solving the outer machine problem of frosting of air conditioner, supplementary air conditioning system's refrigeration. In winter, the air pump drives gas with a certain speed to enter the vortex tube to generate hot gas to defrost the air conditioner external unit, and one end of the semiconductor refrigerating sheet, which generates heat after being electrified, is attached to one side of the heat exchanger of the external unit to defrost the air conditioner external unit. And simultaneously, the utility model designs a supplementary defrosting function of domestic waste water circulation, the heat that contains in the domestic waste water is the outer quick-witted defrosting of air conditioner through the circulation, has realized the high-efficient utilization of heat energy. In summer, cold air generated by the vortex tube is introduced into the room and the semiconductor refrigerating sheet generates cold energy to be supplied to the air conditioner internal unit to assist the air conditioner in refrigerating. In addition, this external solar panel of system and wind driven generator to store the electric energy that will produce in the battery, solar panel and wind driven generator provide clean environmental protection's green energy for the system, ensure the normal steady operation of this system.

When air with a certain speed enters the vortex tube, hot air is discharged from one end of the vortex tube, cold air is discharged from the other end of the vortex tube, the end of the hot air is arranged above an air conditioner external unit, namely, the hot air is always generated in the running process of the air conditioner, the frosting problem cannot occur, and in summer, the cold air discharged from the vortex tube is directly supplied to indoor refrigeration on one hand, and on the other hand, the cold air is used for cooling the compressor to prevent the compressor from being overheated. Meanwhile, the hot end of the semiconductor refrigerating sheet is attached to an air conditioner outdoor unit, when the semiconductor refrigerating sheet is electrified, heat is directly supplied to the air conditioner outdoor unit, and the temperature of the evaporator is further guaranteed not to be lower than 0 ℃; in summer, the cold end of the semiconductor refrigerating sheet is arranged on an air conditioner indoor unit, and indoor cooling can be facilitated. In order to prevent insufficient storage capacity and poor performance of a semiconductor and vortex tube system in bad weather, a set of domestic wastewater recycling and defrosting system is also arranged. In addition, the system adopts the solar panel and the wind driven generator to generate electric energy to be stored in the storage battery, thereby saving energy and having higher economic benefit.
