TECHNICAL FIELD

[0001] The present application relates to the field of air conditioning technology, and particularly relates to a partition-regulating type air supply system for a refrigeration constant-temperature and constant-humidity air conditioning unit. BACKGROUND

[0002] The current constant temperature and humidity air conditioning system is widely used in some high-end residential buildings, office buildings and hospital buildings in the process of refrigeration and air conditioning equipment manufacturing. The constant temperature and humidity air conditioning system is a form of temperature and humidity independent regulation air conditioning system based on independent dehumidification fresh air and radiation cooling and heating. In the temperature and humidity independent regulation air conditioning system, the independent dehumidification fresh air system is the key to ensure that the air conditioning terminal does not produce condensate water and operates in dry working condition. The current independent fresh air system has the following forms: 1. The ordinary heat recovery fresh air handling unit is used, the low temperature cold water of 7 / 12°C is used in summer, the fresh air is dehumidified while being cooled, it is still a combined temperature and humidity control mode, the surface cooler is prone to mold growth, the fresh air quality is poor, and the efficiency is low; 2. The solution dehumidification fresh air handling unit made of LiBr, CaCl2 and other salt solutions with different concentrations is used, the solution dehumidification fresh air handling unit has the functions of total heat recovery, independent dehumidification and sterilization and disinfection, and the equipment itself has the functions of dehumidification in summer and humidification in winter, but the structure is complex and the volume is large; 3. The double cold source fresh air handling unit made of high and low temperature cold sources is used, the high temperature cold source is borne by the centralized high temperature water chiller unit and is used for pre-cooling the fresh air, and the low temperature cold source is generally borne by the built-in compression type refrigeration cycle and is used for deep dehumidification of the fresh air, but a humidification function section needs to be additionally configured in winter to realize the humidification function. A household constant temperature and humidity air conditioning system based on double cold source heat recovery dehumidification fresh air is disclosed in a Chinese patent (authorized publication number CN206709326U), which discloses a household constant temperature and humidity air conditioning system based on double cold source heat recovery dehumidification fresh air, which comprises a household double cold source heat recovery dehumidification fresh air system and a radiation type temperature regulation system. The household double cold source heat recovery dehumidification fresh air system comprises a household double cold source heat recovery dehumidification fresh air exchanger, a fresh air supply system and a return air system. The household double cold source heat recovery dehumidification fresh air exchanger comprises a fresh air exchange module and a dehumidification module. The fresh air supply system comprises a fresh air pipe, a supply air pipe, an air distributor and a flat air supply pipe. The return air system comprises a return air pipe and an exhaust air pipe. The radiation type temperature regulation system comprises an air source cold and hot water chiller unit and a radiation type cooling and heating system. The utility model uses the household double cold source heat recovery dehumidification fresh air exchanger to supply dehumidified fresh air to the residence, combines the radiation type temperature regulation system to provide a constant temperature and humidity air conditioning environment for the household residence, and realizes the same constant temperature and humidity effect as the large-scale centralized air conditioning. The patent technology solves the problem that most of the current applications use the centralized air conditioning system form, that is, the cold water chiller unit and the boiler are centrally arranged to centrally process the cold and heat sources required by the air conditioning system, the cold and heat medium water is transported to the building through the centralized circulating pump, and the fan coil or the radiation type terminal is used to process the indoor temperature. In the residential building, the fresh air required by the air conditioning system is usually processed by the centralized fresh air handling unit arranged on the roof, the processed fresh air is sent to each floor through the centralized vertical air duct, and the air conditioning return air is also collected to the roof through the vertical air duct.In this process, the new air of each household, exhaust air cannot be controlled individually, centralized cold and heat source is also difficult to better match the occupancy rate of the household to adjust. Centralized constant temperature and humidity air conditioning system is difficult to achieve energy saving effect.

[0074] The hot air heating mode is as follows:

[0075] The air compressor 221 compresses and extracts the air outside the unit case 1 into the arc-shaped double-pass pipeline 202;

[0076] The air outside the unit case 1 is filtered by the filter screen 8 before entering the arc-shaped double-pass pipeline 202;

[0081] The hot air enters the air duct pipe 3 through the concentration box 207, is transmitted to the partition adjustment air duct structure 1 5 and the partition adjustment air duct structure 2 6 through the constant humidity air cylinder 401 connected with the air duct pipe 3, and is transmitted to the indoor partition space through the partition adjustment air duct structure 1 5 and the partition adjustment air duct structure 2 6 to complete the hot air supply mode;

[0082] The cold air cooling mode is:

[0083] The air fan 221 compresses and extracts the air outside the unit case 1 into the arc-shaped double-pipe duct 202;

[0084] The air outside the unit case 1 is filtered by the filter screen 8 before entering the arc-shaped double-pipe duct 202;

[0085] The position of the closed rotating plate 211 inside the arc-shaped double-pipe duct 202 is adjusted, the servo motor 215 is started in reverse to drive the worm 214 in reverse, the worm 214 meshes with the worm gear 213 after rotating, and the worm gear 213 drives the closed rotating plate 211 on the transmission rod 212 to adjust to the constant temperature hot air duct 203 to close the constant temperature hot air duct 203;

The high-temperature and high-pressure state of the compressed refrigerant enters the condenser 220 and exchanges heat with the environment. The gaseous refrigerant in the condenser 220 gradually condenses into a liquid, while releasing a large amount of heat. The refrigerant liquid flowing out of the condenser 220 passes through the expansion valve to reduce the pressure and then enters the evaporator 217 inside. The liquid refrigerant rapidly vaporizes and absorbs heat, and the temperature of the constant temperature cold air duct 204 is rapidly cooled by the evaporator 217 to complete the cooling work of the air. The gaseous refrigerant after evaporative heat absorption is again sucked into the compressor 219 through the connecting pipe 218 to perform a cycle cooling work;
