Abstract

The invention discloses a control method and system of a radiant air conditioner. The control method of the radiant air conditioner comprises the following steps that the environmental load information of the environment where at least one indoor unit connected with an outdoor unit is located is obtained; the water temperature of water needing to be supplied to each indoor unit is determined according to the environmental load information of the environment where the indoor unit is located; the highest water temperature of water needing to be supplied to at least one indoor unit is determinedas a first water supply temperature of a first water chilling unit; the lowest water temperature of water needing to be supplied to at least one indoor unit is determined as a second water supply temperature of a second water chilling unit; and a first water supply quantity of the first water chilling unit and a second water supply quantity of the second water chilling unit are controlled according to the dew-point temperature of the environment where each indoor unit is located, so that the air temperature of the environment where each indoor unit is located is made higher than the dew-pointtemperature of the environment where each indoor unit is located. The method capable of adjusting a water system of the air conditioner according to the load requirement of the air conditioner is provided, and thus, an efficient, low-energy-consumption and anti-condensation operation effect of the air conditioner is achieved.

Description

technical field [0001] The present application relates to the field of air conditioners, and in particular, to a control method and system for radiant air conditioners. Background technique [0002] As people have higher and higher requirements for air conditioning comfort and energy saving, radiant air conditioning systems have good application prospects because they can be well combined with low energy consumption or green buildings. Radiant cooling (warming) refers to lowering (raising) the temperature of one or more surfaces in the inner surface of the envelope to form a cold (hot) radiant surface, which relies on the radiation between the radiant surface and the rest of the surface of the human body, furniture and envelope structure. A technical method for cooling (warming) by exchanging heat. The radiant surface can be realized by arranging cold (hot) pipes in the envelope structure, or adding radiant panels on the outer surface of the ceiling or wall. Due to the cha...
