Air conditioning system adopting thermoelectric refrigeration as assistant and capable of independently controlling temperature and humidity

Abstract

The invention discloses an air conditioning system adopting thermoelectric refrigeration as an assistant and capable of independently controlling temperature and humidity. Heat exchangers and thermoelectric refrigeration chips are arranged in an air handling tail end and arranged in sequence from an inlet to an outlet, an output end of a low-temperature cold source is connected with the input end of a control valve, the output end of the control valve is connected with the input ends of the heat exchangers, the output ends of the heat exchangers are connected with the input end of the low-temperature cold source, a refrigeration chip controller is connected with the thermoelectric refrigeration chips by leads and controls the thermoelectric refrigeration chips. The air conditioning system has a simple structure, can realize independent control on the temperature and humidity of air, effectively saves energy consumption and achieves the purpose of fast adjusting the comfortable indoor environment.

Description

technical field [0001] The invention relates to an air conditioning system with independently controlled temperature and humidity assisted by thermoelectric refrigeration. Background technique [0002] Air-conditioning systems are widely used in people's daily work and life, providing people with a comfortable working and living environment. Usually suitable environmental indicators include air temperature and humidity, while conventional air-conditioning systems generally only adjust air temperature, and air humidity It cannot be adjusted separately, so for high-demand comfort air-conditioning systems or industrial air-conditioning systems, external heating sources, such as electric heaters or steam heating, are often required to achieve independent control of humidity. This often leads to the offset of cold and heat sources in the air conditioning system, resulting in large energy consumption. In recent years, an air-conditioning system with independent control of tempera...

[0002] Air-conditioning systems are widely used in people's daily work and life, providing people with a comfortable working and living environment. Usually suitable environmental indicators include air temperature and humidity, while conventional air-conditioning systems generally only adjust air temperature, and air humidity It cannot be adjusted separately, so for high-demand comfort air-conditioning systems or industrial air-conditioning systems, external heating sources, such as electric heaters or steam heating, are often required to achieve independent control of humidity

This often leads to the offset of cold and heat sources in the air conditioning system, and the energy consumption is large

In recent years, an air-conditioning system with independent control of temperature and humidity has been proposed, and the air temperature and humidity are processed separately by different adjustment systems to achieve independent control. For the dehumidification function, the cold water produced by the low-temperature chiller is sent to the fresh air unit for dehumidification; this system has the characteristics of energy saving and high efficiency, but the system uses two sets of different equipment to achieve independent control of air temperature and humidity, resulting in a complicated system. The two systems are completely independent, especially the end of the sensible heat treatment cannot dehumidify, resulting in a large humidity load when the air conditioning system is turned on, and the two systems cannot be fully utilized to work together, resulting in the air-conditioned room not being able to quickly achieve dehumidification and cooling, so that it is impossible to quickly achieve suitable indoor comfort surroundings
