Abstract

The invention discloses a radiation cooling control system and method for an embedded tube type enclosure structure. The system includes a radiation cooling terminal mechanism, a dehumidification and ventilation mechanism, a cold and heat source heat exchange mechanism and a control module. The heat mechanism includes a cold and heat source unit and a heat exchange mechanism. The heat exchange mechanism includes a plate heat exchanger, an electromagnetic three-way valve, a first circulating water pump and a second circulating water pump. The room is equipped with an indoor humidity sensor, an indoor dry bulb Temperature sensor, dew point temperature sensor, wind speed sensor, black ball temperature sensor and surface temperature sensor; the method includes the following steps: 1. parameter setting; 2. real-time signal collection and synchronous upload; 3. adjustment of cooling water temperature at the radiation end; , Adjustment of thermal comfort index PMV value. The invention is adapted to outdoor temperature changes and indoor temperature and humidity changes, so that the indoor thermal environment meets the thermal comfort requirements of indoor personnel and saves energy consumption.

Description

technical field [0001] The invention belongs to the technical field of radiant end cooling control of an embedded tube type enclosure structure, and in particular relates to a radiation cooling control system and method for an embedded tube type enclosure structure. Background technique [0002] The embedded tube enclosure structure radiant cooling system is also called concrete radiant cooling system. The water supply pipe is buried in the enclosure structure, such as a concrete floor, and the heat is transferred through the flow of water in the pipe to achieve the cooling effect. Due to the high thermal inertia of the cold roof (floor) plate itself, the control of this system is different from that of conventional air conditioners. When the surface temperature of the radiant cooling component is lower than the dew point temperature of the indoor air, condensation may occur and affect the indoor air quality. In addition, the current radiant cooling system mostly adopts the...
