An integrated air-conditioning device with induced air supply and radiation for a single chiller

Abstract

The invention discloses an induced draught and radiation integrated air conditioning device with a single water chilling unit. The induced draught and radiation integrated air conditioning device comprises a radiation induction unit, a sectional type air handling unit, a dual-evaporator water chilling unit, a cooling tower, a make-up water tank, a circulation pump, an auxiliary electric heater, a flow control electrically operated valve, a circulation water pump and a return duct, wherein all the components are located indoors. An upper return air inlet and a lower return air inlet are formed in the indoor wall face. The radiation induction unit comprises a still pressure box, an aluminum heat exchanging coil and a box body. The sectional type air handling unit comprises a mixing section, a surface cooling section, a heating section, a humidifying section and a fan section, wherein the mixing section, the surface cooling section, the heating section, the humidifying section and the fan section are arranged in sequence and communicated with one another. The dual-evaporator water chilling unit comprises a high-temperature bushing type evaporator, a low-temperature bushing type evaporator, a compressor, a bushing type condenser, a cooling water circulation water pump and a liquid storage tank. The air conditioning device can flexibly meet air conditioning demands of various seasons, and achieves the effects of high comfort and controllability through coupling of the radiation and induced draught technology and the non-azeotropic refrigerant mixture dual-evaporator water chilling unit.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to an air-conditioning device integrating induced air supply and radiation of a single chiller. Background technique [0002] Compared with traditional air-conditioning methods, such as energy loss, high noise, low comfort, and air quality problems, radiant air-conditioning with high comfort, high efficiency and energy saving, easy installation, and space-saving has attracted widespread attention. At present, all-water ceiling radiant air conditioning systems and floor radiant heating systems are widely used in various buildings. However, this technology also has certain defects: 1. Water leakage problem. The cooling and heating medium pipelines of the radiant air conditioning system are all installed inside the decoration layer. Once the pipeline leaks, it will be more troublesome to maintain; The cost of the method is high; 3. There is a possibility...

Problems solved by technology

However, this technology also has certain defects: 1. Water leakage problem. The cooling and heating medium pipelines of the radiant air conditioning system are all installed inside the decoration layer. Once the pipeline leaks, it will be more troublesome to maintain; The cost of the method is high; 3. There is a possibility of condensation. When the surface temperature of the roof radiant panel is lower than the air dew point temperature in the air-conditioned room, condensation will occur, which will affect people's comfort and the cooling capacity of the radiant air conditioner.

On the one hand, this design increases the initial investment and operating costs of the system, and on the other hand, it also increases the difficulty in system operation management and optimization.
