Embodiment Construction

[0020] In order to facilitate understanding, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiment of the present invention is given in the drawings. However, the present invention can be implemented in many different forms, is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly.

[0021] See figure 1 As shown, a ternary heating polygon having anti-freeze detection, including an indoor unit 100, an outdoor unit 200, and a floor heating module 300, wherein the outdoor unit 200 includes a compressor 210, an outdoor heat exchanger 220, and the first four pass. Valve 230 and the second four-pass valve 240; the floor heating module 300 includes a hydraulic heat exchanger 310 and a thin heating coil 320.

[0022] In the present embodiment, the D, E, C and S interfaces of the first four-pass valve 230 res...

Abstract

The invention discloses a floor heating multi-connection unit with antifreeze monitoring and its antifreeze control method, which also includes an ambient temperature unit arranged at the outdoor heat exchanger and used to detect and obtain the ambient temperature value, arranged at the indoor unit and used for detecting The indoor unit temperature unit for obtaining the temperature value of the internal unit, the first temperature unit arranged on the water flow path of the hydraulic heat exchanger and used to detect the obtained water temperature value, and the first temperature unit arranged on the outlet of the refrigerant flow path of the hydraulic heat exchanger and used for detection The second temperature unit that obtains the temperature value of the liquid pipe; the floor heating multi-connection includes floor heating mode and non-floor heating mode, which effectively improves the linkage antifreeze protection among the indoor unit, outdoor unit and hydraulic module, and improves the floor heating multi-connection and Reliability during use, solve the root cause of freezing and cracking heat exchangers from the system as a whole, and greatly reduce the risk of liquid return and freezing cracks.

Description

Technical field [0001] The present invention relates to the technical field of terminating multi-link, in particular, refers to a ternary heating and aircraft having anti-freeze monitoring and its anti-freeze control method. Background technique [0002] In the existing floor heating multi-link, there are both multiple machine systems, and a hydrofilm system for hydraulic modules. To ensure that the normal switching of the floor heating multi-haircraft, it is necessary to effectively prevent it in low temperature environments. Protection, and existing anti-frozen measures, for the water system, only rely on the temperature of the hydraulic module, does not involve the detection of the host, the standard is not true; and for multi-machine systems, depending on the detection of the indoor unit Temperature, does not involve the detection of the host, and the standard is not true. The above-described multi-haired machine system, the antifreeze measures of the water system system are ...
