Radiation air-conditioning system with fresh air dehumidification function and cold supply control method thereof

Abstract

The invention provides a radiation air-conditioning system with a fresh air dehumidification function and a cold supply control method thereof. The radiation air-conditioning system is integrated with cold source refrigeration equipment, so that two types of working media with different temperatures can be generated under a cold supply working condition and are used for radiation cold supply and fresh air dehumidification; a system framework is simplified under the condition that the system has good radiation temperature control and fresh air dehumidification functions, so that the whole construction cost and energy consumption of the system are reduced; the cold supply control method of the radiation air-conditioning system is combined and the system can be operated at a fresh air dehumidification cold supply mode, a radiation cold supply mode, a step cold supply mode or a parallel cold supply mode according to requirements of different conditions, so that respective independent operation control of the radiation temperature control and fresh air dehumidification functions, and cooperative operation control of the radiation temperature control and fresh air dehumidification functions are realized; the wastes and loss of a cold source refrigeration amount under the cold supply working condition of the system are reduced, so that the whole energy consumption of the system is reduced; and a new solution is provided for integration of the radiation air-conditioning system and the fresh air dehumidification function.

Description

technical field [0001] The invention relates to the field of indoor ventilation technology and air conditioning technology, in particular to a radiation air conditioning system with fresh air dehumidification function and a cooling control method thereof. Background technique [0002] With the continuous development of social economy, people's requirements for indoor comfort continue to increase. For the traditional air conditioning system, there are still some problems, such as the loss caused by the coupling of temperature and humidity, the feeling of convection, the noise of the coil air supply, and so on. The radiant air-conditioning system is more and more favored by people because of its low noise, good thermal comfort, energy saving and building space saving. It is a new type of air-conditioning system that has developed rapidly in my country in recent years. [0003] The end of the radiant panel of the radiant air conditioning system is a kind of flat air-conditioni...

AI Technical Summary

Problems solved by technology

[0006] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a cooling system with good radiation control and fresh air dehumidification functions, lower construction cost and energy consumption cost, and less cooling loss under cooling conditions. A radiant air-conditioning system with fresh air dehumidification function to solve the problems in the prior art that the overall cost of the system combined with radiant air-conditioning and fresh air dehumidification is relatively high, the cost of energy consumption is high, and the cooling capacity of the system as a whole is lost under cooling conditions.
