Radiant Air Conditioning System with Variable Refrigerant Flow Rate

Abstract

A variable-refrigerant-flow radiant air-conditioning system, comprising an indoor unit (2), an outdoor unit (1), a distribution manifold (3), a radiating end (4) and a dew point temperature controller (49). The indoor unit (2) is in serial connection with the outdoor unit (1), the radiating end (4) is connected to the indoor unit (2) via the distribution manifold (3), and the dew point temperature controller (49) is connected to the distribution manifold (3), and is configured to sense an indoor temperature change and humidity change, and prevent, by closing a water-recycling valve in advance, potential condensation on a radiant surface when an airflow system malfunctions. The radiant air-conditioning system can heat and humidify in winter, cool and dehumidify in summer, and purify outdoor air before allowing the outdoor air to flow into indoor space, ensuring optimal indoor temperature, humidity and cleanliness for living comfort.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a radiation air conditioning system with variable refrigerant flow. Background technique [0002] The radiant air-conditioning system is an air-conditioning system that uses the principle of radiation to adjust the indoor temperature, and uses fresh air to control and adjust the indoor humidity and air cleanliness. Compared with the traditional air conditioner that relies on air supply to adjust the indoor temperature, the radiant air conditioning system has obvious advantages, such as: no strong wind feeling, no indoor air conditioner wall-mounted or floor machine noise, and the indoor temperature can be adjusted at the same time. Humidity, indoor air is permanently fresh and clean, energy-saving operation, etc. [0003] At present, most of the radiant air conditioners in the market are centralized systems. The centralized radiant air conditioner system is mainly reflected in th...

AI Technical Summary

Problems solved by technology

At present, the household radiant air conditioning system is mostly composed of air-cooled heat pump units combined with fresh air processing units, water heat exchangers, humidifiers, filters, radiation terminals and other equipment. However, there are generally problems such as poor performance coupling of equipment, too many types of equipment, large installation space, complex control, poor stability, limited scope of application, complex installation and debugging, high cost, easy to freeze, and poor energy-saving effect.
