Fresh air dehumidifying system for low-temperature radiation air conditioner and control method of system

Abstract

The invention discloses a fresh air dehumidifying system for a low-temperature radiation air conditioner. The system comprises a refrigeration system, a refrigeration system controller, a radiation system capable of exchanging heat with the refrigeration system through a water circulation system, a control panel, a mater control board, a fresh air dehumidifying system and a fresh air dehumidifying system controller; the fresh air dehumidifying system comprises a frequency conversion compressor, a surface air cooler, an evaporator, a condenser and a direct-current frequency conversion draught fan, an air filter net is arranged on one side of the surface air cooler, an outlet of the water circulation system is connected with an inlet of the radiation system and an inlet of the surface air cooler, an inlet of the water circulation system is connected with an outlet of the radiation system and an outlet of the surface air cooler, an exhaust opening of the frequency conversion compressor is connected with an inlet of the condenser, an outlet of the condenser is connected with an inlet of the evaporator, an outlet of the evaporator is connected with an air inlet of the frequency conversion compressor, and the fresh air dehumidifying system controller comprises a communication module, a control module, a drive module and a sensor module. The invention further discloses a control method of the fresh air dehumidifying system for the low-temperature radiation air conditioner.

Description

technical field [0001] The invention relates to the field of radiation-type air-conditioning systems, in particular to a fresh air dehumidification system for low-temperature radiation-type air-conditioning and a control method thereof. Background technique [0002] The blowing of household air conditioners during the heating process makes people feel cold and uncomfortable. In order to solve this problem, two sets of systems, ordinary household air conditioners and floor heating, have appeared in the market to solve the problem of heating discomfort. In fact, the blowing feeling will make people uncomfortable even when cooling, and the use of radiant air conditioners can better solve the discomfort of traditional air conditioners and improve the comfort of users when using air conditioners. The low temperature represented by the capillary end system Since the radiant air conditioner significantly increases the evaporation temperature of the refrigeration system, the energy ...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the refrigerant goes to the waterway, the waterway goes to the proportional regulating valve (optional), and then to the casing heat exchanger, and then exchanges heat with the input indoor air. Obviously, after several conversions, the heat exchange efficiency is greatly reduced, and the entire system Significant increase in energy consumption and cost, which is not conducive to the promotion of low-temperature radiant air-conditioning systems

[0006] 2. The refrigeration system must not only meet the indoor temperature, but also balance the condensation heat and dehumidification effect of the fresh air dehumidifier. Therefore, the compressor capacity of the refrigeration system will take the maximum of the three requirements, which will lead to a significant increase in the energy consumption of the compressor of the refrigeration system.
