Water supply control method, device and system of radiant air conditioner

Abstract

The invention discloses a water supply control method, device and system of a radiant air conditioner. The water supply method comprises the following steps that environmental state information of anindoor space where the air conditioner is located is obtained; at least one control instruction selected from an air supply instruction, a dehumidification instruction, a refrigeration instruction, aheating instruction, a refrigeration air-supply instruction and a heating air-supply instruction is generated according to the environmental state information, wherein the air supply instruction is used for controlling a first water supply unit to supply water to a fan coil, the dehumidification instruction is used for controlling a second water supply unit to supply water to a dehumidification coil, the refrigeration instruction is used for controlling the first water supply unit and the second water supply unit to supply water to a refrigeration / heating coil, the heating instruction is usedfor controlling the first water supply unit to supply water to the refrigeration / heating coil, the first water supply unit is used for supplying water at a first temperature, and the second water supply unit is used for supplying water at a second temperature; and the first water supply unit and / or the second water supply unit are / is controlled to supply water to the fan coil, the dehumidificationcoil and the refrigeration / heating coil based on the control instruction. By adoption of the water supply control method, device and system of the radiant air conditioner, independent control over dehumidification and refrigeration is achieved, and thus, the dew point risk is reduced.

Description

technical field [0001] The present application relates to the field of air conditioning, in particular to a water supply control method, device and system for radiant air conditioning. Background technique [0002] As we all know, the energy consumption of air conditioners accounts for more than half of the energy consumption of the entire building. Therefore, it is imminent to reduce the energy consumption of air conditioners. Radiant air-conditioning has become the direction of future air-conditioning development due to its advantages of energy saving and no wind feeling. [0003] For radiant air conditioners, the conventional air conditioning treatment method generally adopts the regulation and control principle of thermal coupling. In summer, a low-temperature cold source is used to cool and condense and dehumidify the air through air-cooled cookies, so as to provide dry and clean air indoors and realize heat dissipation and cooling. The joint treatment of dehumidificat...

Problems solved by technology

[0004] However, since cooling and dehumidification share a set of water systems for unified treatment, considering that the temperature of the cold source is limited by the dew point of the indoor air, usually only a cold source with a temperature of 15-18°C is required to meet the cooling requirements. The process of removing waste heat has to Share with the dehumidification process the low-temperature refrigeration of 5-7°C

It can be seen that the heat-humidity combined system of the traditional radiant air conditioner will not only lead to waste of energy utilization grade, but also the low-temperature cold source may cause condensation on the radiant panel, causing mold to multiply and affecting the indoor environment
