Description

Technical Field

[0001] This utility model belongs to the field of cooling and heating compensation technology, specifically relating to a personalized local compensation air conditioning unit based on a radiant cooling and heating system. Background Technology

[0002] Radiant cooling and heating systems have a lag in regulation. When outdoor solar radiation is strong, buildings with five-balance systems cannot respond quickly to changes in room load, which can easily lead to localized temperature imbalances in the rooms.

[0003] The following situations exist: (1) In large-sized residential buildings 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 skylights, especially those facing west, will allow the interior to receive extremely high solar heat in a short period of time, particularly in the afternoon, causing the temperature to rise sharply, possibly by several degrees Celsius per hour; (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; for the above two situations, the adjustment of the solar radiation cooling and heating 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. The uniform heating and cooling supply standards are 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] This utility model aims to provide a personalized local compensation air conditioning unit based on a radiant cooling and heating system, which can quickly balance indoor temperature differences, regulate local room demand and instantaneous heat load, and solve the problem of excessively high and unbalanced local room temperature caused by the lag in the regulation of the radiant cooling and heating system.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a personalized local compensation air conditioning unit based on a radiant cooling and heating system, including a housing and a filter sterilizer, evaporator, condenser, plate heat exchanger, fan, circulating water pump, and compressor installed inside the housing. The filter sterilizer is installed at the air inlet end of the housing. The compressor is divided into two delivery routes: one connected to the air inlet end of the condenser and equipped with a dehumidification solenoid valve, and the other connected to the air inlet end of the plate heat exchanger and equipped with a cooling solenoid valve. The plate heat exchanger is connected to the circulating water of the radiant cooling and heating system, and a circulating water pump is installed at the water inlet end. The air outlet pipe of the plate heat exchanger and the air outlet pipe of the condenser are merged to form a combined pipe. The combined pipe is connected to the air inlet end of the evaporator, and the air outlet end of the evaporator is connected to the air inlet end of the compressor, thus forming a loop. When only the dehumidification solenoid valve is open, a dehumidification mode is formed; when the cooling solenoid valve and the circulating water pump are started, a cooling mode is formed.

[0006] As a preferred embodiment of the above scheme, the combined pipeline adopts a capillary tube to regulate the gas flow rate from the condenser to the evaporator.

[0007] Preferably, the enclosure is a cabinet type and equipped with a non-contact infrared temperature sensor for detecting the location of living organisms. The air outlet of the enclosure is equipped with adjustable fan blades and a drive motor that provides the adjustment power for the adjustable fan blades. When a person is detected approaching, the adjustable fan blades adjust to blow air upwards. When no one is detected approaching, the adjustable fan blades adjust to blow air horizontally to avoid cold air blowing directly on the human body and causing discomfort. At the same time, when no one is around, the cold air is directly delivered to the activity area to ensure a comfortable temperature in the activity area and save energy consumption.

[0008] A further preferred embodiment is that the personalized local compensation air conditioning unit shares temperature and humidity sensor data with the radiant cooling and heating system. When the indoor humidity is detected to be higher than the set value, the dehumidification mode is activated; when the temperature is detected to be higher than the set temperature, the cooling mode is activated. The personalized local compensation air conditioning unit and the radiant cooling and heating system work together to ensure that the personalized local compensation air conditioning unit provides timely compensation.

[0009] The beneficial effects of this utility model are:

[0010] (1) Compared with the lag in the regulation of radiant cooling and heating systems, this application uses a personalized local compensation air conditioning unit for cooling compensation, which can quickly respond to changes in room heat load and achieve rapid indoor cooling. The air conditioning unit of this application can be placed near the enclosed balcony or large windows of the room to effectively alleviate the impact of strong sunlight on the temperature near the window and improve the overall room comfort.

[0011] (2) In the cooling mode, the gas from the compressor passes through the cooling solenoid valve and the plate heat exchanger in sequence, and uses the circulating water of the radiant cooling and heating system for heat exchange. Then, it enters the evaporator through the combined pipeline of the outlet pipe of the plate heat exchanger and the outlet pipe of the condenser. The evaporator cools the gas and dehumidifies it at the same time. In the dehumidification mode, the gas from the compressor enters the condenser through the dehumidification solenoid valve, and then enters the evaporator through the combined pipeline. After exiting the evaporator, it returns to the compressor. While the evaporator cools and dehumidifies, the condenser dissipates heat, causing the gas in the box to cool down and then warm up. The temperature difference is not large, and it can only achieve the dehumidification function, effectively reducing the system energy consumption.

[0012] In summary, this utility model has the advantages of rapid cooling, balanced temperature difference, flexible control, and energy saving. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0014] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0015] like Figure 1 As shown, a personalized local compensation air conditioning unit based on a radiant cooling and heating system consists of a housing 10 and a filter sterilizer 1, an evaporator 2, a condenser 3, a plate heat exchanger 4, a fan 5, a circulating water pump 6, and a compressor 7 installed inside the housing 10.

[0016] The filter and sterilizer 1 is installed at the air inlet of the housing 10.

[0017] The compressor 7 is divided into two delivery routes: one is connected to the air inlet of the condenser 3 and equipped with a dehumidifying solenoid valve 8, and the other is connected to the air inlet of the plate heat exchanger 4 and equipped with a refrigeration solenoid valve 9.

[0018] The plate heat exchanger 4 is connected to the circulating water of the radiant cooling and heating system, and a circulating water pump 6 is installed at the inlet end.

[0019] The outlet pipe of plate heat exchanger 4 and the outlet pipe of condenser 3 are combined to form a combined pipe 31.

[0020] The combined pipe 31 is connected to the air inlet of the evaporator 2.

[0021] The outlet of evaporator 2 is connected to the inlet of compressor 7, thus forming a circuit.

[0022] The merging pipeline 31 preferably uses a capillary tube.

[0023] The enclosure 10 is preferably a vertical cabinet type and is equipped with a non-contact infrared temperature sensor for detecting the location of organisms.

[0024] The air outlet of the housing 10 is equipped with adjustable angle fan blades and a drive motor that provides the adjustment power for the adjustable angle fan blades.

[0025] When someone is detected approaching, the adjustable fan blades are adjusted to blow air upwards; when no one is detected approaching, the adjustable fan blades are adjusted to blow air horizontally.

[0026] When only the dehumidification solenoid valve 8 is open, the dehumidification mode is activated; when the refrigeration solenoid valve 9 and the circulating water pump 6 are started, the refrigeration mode is activated.

[0027] Personalized local compensation air conditioning units share temperature and humidity sensor data with radiant cooling and heating systems.

[0028] When the indoor humidity is detected to be higher than the set value, the dehumidification solenoid valve 8 is activated to start the dehumidification mode. When the temperature is detected to be higher than the set temperature, the cooling solenoid valve 9 and the circulating water pump 6 are activated to start the cooling mode. When the indoor temperature reaches the set temperature, the operation stops.

[0029] When multiple individualized local compensation air conditioning units are in operation, if the temperature difference between the supply and return water of the radiant cooling and heating system exceeds the set value, it indicates that the overall building load is too high. The operating parameters of the radiant system host can be optimized in conjunction with the system, such as reducing the supply water temperature.
