Energy-saving air conditioning box capable of achieving accurate control over high, medium and low temperature and humidity

Abstract

The invention belongs to the technical field of energy-saving air conditioners, and particularly relates to an energy-saving air conditioning box capable of achieving accurate control over high, medium and low temperature and humidity. The air conditioning box comprises an air inlet section fan, a filter section filter, a surface cooling section heat exchanger, a front heating section electric heater, a direct expansion section direct expansion type coil pipe, a heat recovery section heat exchanger, a rear heating section electric heater, a humidifying section electric humidifier and a micro heating section electric heater which are connected in sequence; a dry-bulb temperature sensor and a humidity temperature sensor are arranged at an air supply outlet of the air-conditioning box; the compression condensing unit comprises a loop connected with an inlet and an outlet of the direct-expansion coil of the direct-expansion section; an inlet of the condenser is connected with an outlet of the heat source tower through a first pipeline, and an outlet of the condenser is connected with an inlet of the heat source tower through a second pipeline. An outlet of the heat recovery section heat exchanger is connected with the first pipeline through a third pipeline, and an inlet of the heat recovery section heat exchanger is connected with the second pipeline through a fourth pipeline.

Description

technical field [0001] The invention belongs to the technical field of energy-saving air conditioners, and in particular relates to an energy-saving air conditioner box capable of realizing precise control of high, medium and low temperature and humidity. Background technique [0002] In the refrigeration and air conditioning industry, the electric energy consumed by air conditioners in large public buildings accounts for about half of the total electric energy; in the medium and low temperature refrigeration industry, precision industry, refrigeration and air conditioning industry and other occasions, the accuracy requirements for the temperature and humidity of the storage environment and living and working environment are also increasing day by day. Therefore, it is of great significance to save the energy consumption of air-conditioning equipment and develop energy-saving air outlet equipment that can achieve precise control of high, medium and low temperature and humidi...

AI Technical Summary

Problems solved by technology

The problems in the above system are as follows: screw compressors, scroll compressors or piston compressors are coupled to meet the needs of high, medium and low temperature air outlets at the same time, but it causes an increase in initial investment costs and operating costs; the air conditioning box has no front Electric heating has caused serious frosting and difficult defrosting problems when the air is blown at low temperature; the air conditioning box is not equipped with front and rear heat exchangers, and the cold heat of the cold and hot media inside and outside the system is not effectively used to cool down, dehumidify and heat up the air, which does not fully save energy ;Traditional air-conditioning boxes can not meet the requirements for precise control of high, medium, low temperature and humidity

[0004] At present, in low-temperature freezers such as seed banks and flower banks, the storage requirements for the accuracy of the ambient temperature and humidity are very high, and the storage requirements cannot be well met only by using a compression condensing unit; in some air-conditioning equipment tests In the room, the accuracy requirements for the ambient temperature and humidity are also very high, and the temperature range is also very wide, and the traditional air-conditioning box cannot meet the requirements; in some production workshops and warehouses of the pharmaceutical industry, leather goods warehouses and leather materials in leather goods factories, The precision workshop of the precision equipment factory, the storage of classical calligraphy and painting, and the storage of agricultural and sideline products also have high requirements for the accuracy of environmental temperature and humidity, and new energy-saving and precise control equipment is needed to meet their use requirements.
