The floor radiant coil used can switch the refrigerant or heat medium according to the needs of users to meet the comfort requirements in different seasons. The realized laying of the surface does not need to be provided with a thermal insulation layer and a concrete filling layer, which increases the heat transfer and reduces the construction cost at the same time. The realized laying method does not need to be provided with expansion joints and reduces the construction process.

detailed description

In order to make the above purpose, features and advantages of the present utility model more obvious and understandable, the specific implementation of the present utility model will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a full understanding of the present invention. However, the utility model can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below .

It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical", "horizontal", "left", "right" and similar expressions used in the present invention are for the purpose of illustration only, and do not represent the only embodiment.

Unless otherwise defined, all technical and scientific terms used in this utility model have the same meaning as commonly understood by those skilled in the technical field of this utility model.

It can withstand large floors and loads, and there is no need to set up insulation layers and concrete filling layers in the surface layer. At the same time, the refrigerant or heat medium can be switched according to user needs to meet the comfort requirements in different seasons. In summer, the internal cooling source of the buried floor radiant coil 3 can provide cold water for chillers, etc., and the temperature of the supply and return water is 18°C/21°C. , down the floor, and then through radiation heat exchange and convection heat transfer to the rooms on the upper and lower floors of the floor; in winter, the heat source in the buried floor radiant coil 3 can be a boiler, etc., and the temperature of the supply and return water is 35°C/25°C , the heat transfer mode is the same as in summer.
