Abstract

The invention discloses a ground heating VRF with the antifreezing monitoring function and an antifreezing control method thereof. The ground heating VRF comprises an environment temperature unit, anindoor unit temperature unit, a first temperature unit, and a second temperature unit; the environment temperature unit is arranged at an outdoor heat exchanger and used for detecting and obtaining the environment temperature value; the indoor unit temperature unit is arranged at an indoor unit and is used for detecting and obtaining the indoor unit temperature value; the first temperature unit isarranged on the water flow path of a hydraulic heat exchanger and is used for detecting and obtaining the water temperature value; the second temperature unit is arranged on the outlet of a refrigerant flow path of the hydraulic heat exchanger and is used for detecting and obtaining the temperature value of a liquid pipe; and the ground heating VRF comprises the ground heating mode and the non ground heating mode, effectively improves the linkage antifreezing protection of the indoor unit, the outdoor unit and a hydraulic module, improves the reliability during the using process, finds out the root cause of generating frost crack of the heat exchanger from the entire system and greatly lowers the risks of liquid return and frost crack.

Description

technical field [0001] The invention relates to the technical field of floor heating multi-connectors, in particular to a floor heating multi-connector with antifreeze monitoring and an antifreeze control method thereof. Background technique [0002] In the existing floor heating multi-line dual supply system, there are both multi-line systems and hydraulic module water machine systems. In order to ensure the normal switching operation of the floor heating multi-line systems, it is necessary to effectively prevent freezing of the non-working unit systems in low temperature environments. However, in the existing anti-freezing measures, for the water machine system, it only relies on detecting the temperature of the hydraulic module, and does not involve the detection of the main engine, so it can cure the symptoms, not the root cause; Temperature, which does not involve the detection of the host, is a temporary solution, not a permanent cure. The antifreeze measures of the a...
