Description

Technical Field

[0001] This application relates to the field of temperature control, and in particular to an intelligent temperature control device for central air conditioning and underfloor heating based on dynamic dew point regulation. Background Technology

[0002] Modern users have increasingly sophisticated requirements for indoor comfort, no longer satisfied with simple "cold" or "hot," but pursuing a comfortable experience with constant temperature and humidity, no drafts, no noise, and uniform temperature distribution. Currently, most central air conditioning and underfloor heating systems are physically and independently controlled. Users need to operate two different thermostats (or even multiple zone thermostats) and set different temperature targets. This prevents energy optimization (e.g., underfloor cooling not being utilized in summer), and using underfloor cooling mode in summer can easily cause condensation on the floor. Furthermore, the freeze protection of the temperature control equipment relies solely on the main unit (wall-hung boiler, air source heat pump, etc.), and there is a risk of the system pipes freezing and cracking when the manifold valve is closed.
