Description

Technical Field

[0001] The invention relates to the technical field of air conditioning, and in particular to an air supply system for a zone-regulated refrigeration constant temperature and humidity air conditioning unit. Background Art

[0002] In the current refrigeration and air conditioning equipment manufacturing process, the constant temperature and humidity air conditioning system is widely used in some high-end residential, office and hospital buildings. The constant temperature and humidity air conditioning system is a form of independent temperature and humidity control air conditioning system based on independent dehumidification and fresh air, radiant cooling and heating. In the independent temperature and humidity control air conditioning system, the independent dehumidification and fresh air system is the key to ensure that no condensation water is generated at the air conditioning terminal and that it operates in a dry working state. At present, there are mainly the following forms of independent fresh air systems: one is to use ordinary heat recovery fresh air units, and use 7 / 12°C low-temperature cold water in summer to dehumidify the fresh air while cooling it down. It is still a method of combined temperature and humidity control. The surface cooler is prone to mold growth, the fresh air quality is poor, and the efficiency is low; the second is a solution dehumidification fresh air unit made by using salt solutions such as LiBr and CaCl2 at different concentrations to absorb different water vapor capacities. The solution dehumidification fresh air unit has the functions of full heat recovery, independent dehumidification, and sterilization, and the equipment itself also has the functions of dehumidification in summer and humidification in winter, but the structure is complex and the volume is large; the third is a dual-cold source fresh air unit made of high and low temperature cold sources. The high-temperature cold source is borne by a centralized high-temperature chiller for pre-cooling the fresh air, and the low-temperature cold source is generally borne by a built-in compression refrigeration cycle for deep dehumidification of the fresh air, but in winter, a humidification function section needs to be configured separately to realize the humidification function. A Chinese patent discloses a household constant temperature and humidity air conditioning system based on dual cold source heat recovery and dehumidification of fresh air (authorization announcement number CN206709326U). The patent technology discloses a household constant temperature and humidity air conditioning system based on dual cold source heat recovery and dehumidification of fresh air, including a household dual cold source heat recovery and dehumidification fresh air system and a radiant temperature adjustment system. The household dual cold source heat recovery and dehumidification fresh air system includes a household dual cold source heat recovery and dehumidification fresh air ventilator, a fresh air supply system and a return air system. The household dual cold source heat recovery and dehumidification fresh air ventilator includes a fresh air ventilation module and a dehumidification module. The fresh air supply system includes a fresh air duct, an air supply duct, an air distributor and a flat air supply duct; the return air system includes a return air duct and an exhaust duct; the radiant temperature adjustment system includes an air source hot and cold water unit and a radiant cooling and heating system. The utility model adopts a user-type dual cold source heat recovery dehumidification fresh air ventilator to supply dehumidified fresh air to the residence, and combines it with a radiant temperature control system to provide a constant temperature and humidity air-conditioning environment for the household residence, achieving the same constant temperature and humidity effect as a large-scale centralized air conditioner. This patented technology solves the problem that most of the currently applied projects use a centralized air-conditioning system, that is, a centralized chiller, boiler, etc. are used to centrally process the cold and heat sources required by the air-conditioning system, and the cold and hot media water is transported to the building through a centralized circulation pump, and the indoor temperature is treated by a fan coil or a radiant terminal. In residential buildings, the fresh air required by the air-conditioning system is usually processed by a centralized fresh air unit installed on the roof. The treated fresh air is sent down to each floor through a centralized vertical air duct, and the air-conditioning return air is also concentrated through the vertical air duct to the roof for discharge.In this process, the fresh air and exhaust air of each household cannot be controlled individually, and the centralized cold and heat sources are difficult to adjust according to the occupancy rate of the residents. The centralized constant temperature and humidity air conditioning system is difficult to achieve energy saving effects. The current fresh air treatment equipment is large equipment for centralized air conditioning systems. Ordinary household fresh air systems can meet this fresh air demand, but cannot achieve the dehumidification function.

[0003] However, in the existing technology, in scenarios such as laboratories that require zoned air supply, the indoor air is very dry when the internal humidity is reduced after the wind air is filtered and air supply is required for a long time. At the same time, heating and cooling as well as air exhaust from indoor zoned spaces are required in laboratories, workshops and other places. It is necessary to solve the problem of simultaneous heating and cooling of zoned spaces and exhaust of dirty spaces in zoned spaces in the existing technology.

The hot air is transmitted to the plurality of partition regulating air duct structures 1 5 and the plurality of partition regulating air duct structures 2 6 through the constant humidity air cylinder 401 connected to the air duct 3. The hot air is transmitted to the indoor partition space through the partition regulating air duct structure 1 5 and the plurality of partition regulating air duct structures 2 6, thus completing the working mode of the hot air supply mode.
