Description

Technical Field

[0001] This utility model belongs to the field of cooling and heating technology, specifically relating to a multi-functional air conditioning unit. Background Technology

[0002] When outdoor solar radiation is strong, buildings with five-balance systems exhibit lag and cannot respond quickly to changes in room load, which can easily lead to localized temperature imbalances of excessively high or low temperatures.

[0003] The following situations exist: (1) In large-sized apartments with good ventilation, the south side receives ample sunlight while the north side receives less sunlight, resulting in a severe imbalance in heat load. Large glass rooms, especially those facing west, will generate extremely high solar heat gain in a short period of time, particularly in the afternoon, causing the temperature to rise sharply, possibly by several degrees Celsius per hour. However, in winter, the rooms become even colder due to the windows. (2) Enclosed balconies, as independent thermal spaces, become "buffer zones" and "temperature amplifiers" for heat / cold storage, which will interfere with the microclimate of the living room. In response to the above two situations, the light balance system is insufficient to quickly balance the temperature difference. (3) For high-rise and low-rise buildings with uniform heating and cooling supply standards, the vertical microclimate, such as temperature and radiation, varies greatly. A uniform heating and cooling supply standard is unfair and difficult to balance. The centralized radiant heating and cooling system provides cold and hot water with basically the same temperature to residents of different heights and orientations throughout the building, or the adjustment range is limited, which basically ignores the huge actual load differences between different floors / or orientations. Utility Model Content

[0004] The present invention aims to provide a multi-functional air conditioning unit that can quickly balance indoor temperature differences, regulate local room demand and instantaneous heat load, and solve the problem of unbalanced local room temperature caused by the inability to quickly respond to changes in room load.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a multi-functional air conditioning unit, including a housing and a fan, condenser, evaporator, evaporator switch valve, plate heat exchanger, compressor, water cooler, and purification filter mechanism, all installed inside the housing. The housing has an air inlet on the lower layer and an air outlet on the upper layer. The purification filter mechanism and water cooler are located on the lower layer of the housing, with the purification filter mechanism close to the air inlet. The condenser, evaporator, and fan are located on the upper layer of the housing. A four-way valve is installed on the compressor output pipe. The first port of the four-way valve is connected to a dehumidification and refrigeration pipe, the second port of the four-way valve is connected to the lower interface of the evaporator to form a heating pipe, and the third port of the four-way valve is connected to the compressor input end to form a recovery pipe. The dehumidification and refrigeration... The pipeline is divided into two parts: a dehumidification pipeline connected to the lower interface of the condenser and a refrigeration pipeline connected to the lower interface of the plate heat exchanger. The upper interfaces of the condenser and evaporator are both connected to the upper interface of the plate heat exchanger, forming four interconnected ventilation paths that share a single one-way throttle valve. Each ventilation path is guided by a one-way valve. The diversion switch valve is flush with the top of the evaporator and aligned with the lower air inlet. A circulating water pump and a three-way valve are installed sequentially along the water flow direction on the inlet pipe connected to the cold and hot water source. The outlet pipe of the three-way valve is connected to the inlet of the water cooler and the outlet pipe is connected to the inlet of the plate heat exchanger. The outlet of the water cooler is connected to the outlet pipe, and the outlet of the plate heat exchanger is connected to the cold and hot water source, thus forming a circulation with the cold and hot water source.

[0006] As a preferred embodiment of the above solution, the purification and filtration mechanism includes a nano-photocatalytic air purification device and a composite filter. The appropriate selection of equipment ensures the air purification effect.

[0007] A further preferred embodiment is that the dehumidification pipe is equipped with a dehumidification valve, and the refrigeration pipe is equipped with a refrigeration valve. When the dehumidification pipe needs to be used, the dehumidification valve is turned on, and when the refrigeration pipe needs to be used, the refrigeration valve is turned on. The two are mutually corresponding and the design is reasonable.

[0008] More preferably, the fan is installed on the upper layer of the housing and equipped with an electric air valve to ensure that air enters and exits in one direction.

[0009] A further preferred embodiment includes an intelligent control system, which comprises a non-contact infrared temperature sensor and a temperature and humidity sensor. The non-contact infrared temperature sensor is used to detect whether a living organism is approaching, and the temperature and humidity sensor can be used in conjunction with the temperature and humidity sensor built into the Five Balances system to detect the ambient temperature in a timely manner and adjust the mode accordingly.

[0010] More preferably, the air outlet is equipped with adjustable angle fan blades and a drive motor that provides angle adjustment for the adjustable angle fan blades, so as to detect whether people are approaching based on a non-contact infrared temperature sensor, and avoid blowing directly on people and affecting their comfort.

[0011] Further preferably, six one-way valves are used, and they are arranged in two groups with opposite directions. The ventilation path from the condenser to the plate heat exchanger passes through a one-way valve located at a high position, a throttling valve, and a one-way valve located at a low position in sequence. The ventilation path from the evaporator to the plate heat exchanger passes through two one-way valves located at high positions, a throttling valve, and a one-way valve located at a low position in sequence. The ventilation path from the plate heat exchanger to the condenser passes through a one-way valve located at a high position, a throttling valve, and a one-way valve located at a low position in sequence. The ventilation path from the plate heat exchanger to the evaporator passes through a one-way valve located at a high position, a throttling valve, and a one-way valve located at a low position in sequence. This ensures that the pipeline is streamlined, reduces the cost of consumables, and avoids the accumulation and redundancy of pipelines.

[0012] The beneficial effects of this utility model are:

[0013] (1) Compared with the current system, which cannot respond quickly to changes in room load, the personalized air conditioning unit of this application can be linked with the original five-balance system and connected to the cold and hot water source of the five-balance system. The cold and hot water source of the five-balance system is used for cooling and heating compensation, which can quickly respond to changes in room heat load and achieve rapid indoor cooling. The air conditioning unit of this application is placed near the enclosed balcony or large glass window of the room to effectively alleviate the impact of strong sunlight or cold air on the temperature near the window and improve the overall room comfort. In the absence of the five-balance system, as long as there is cold and hot water source, it can be connected to the air conditioning unit of this application to achieve independent heating, cooling and dehumidification. The air conditioning unit of this application can quickly respond to the demand and achieve immediate cooling and heating functions.

[0014] (2) The intelligent control system is equipped with energy-saving cooling mode, rapid cooling and dehumidification mode, dehumidification mode and heating mode. It can automatically or manually adjust the mode according to the ambient temperature and humidity. It has a variety of functions to fully meet the diverse needs of residents and improve the comfort of life.

[0015] In summary, this utility model has the advantages of rapid cooling, balanced temperature difference, flexible control, and energy saving. Attached Figure Description
