Description

A ground radiation cooling and heating module

technical field

The utility model belongs to the technical field of home flooring, and relates to a ground radiation cooling and heating module of a ground radiation air conditioning system.

Background technique

The floor radiant air conditioning system is a method in which cold or hot water at a specific temperature circulates in the coil system buried under the floor to cool or heat the entire floor, and radiates cooling or heating to the room evenly through the ground. Because the indoor temperature of the ground radiation air-conditioning system changes evenly, there is no sense of blowing, it is soft and quiet, the human body feels comfortable, and it does not affect the overall appearance of the room. Therefore, the plane radiation air-conditioning system that provides heating in winter and cooling in summer has gradually been widely adopted.

Common ground heating and cooling methods are very complicated in the laying process. The traditional wet engineering method commonly used at present is the landfill type. Generally, the base layer of the floor slab is leveled with cement mortar, and then a thermal insulation board with a thickness of not less than 20mm is laid on it. The upper part of the board is often compounded with a layer of tin foil or aluminum foil, and then The water pipes are evenly arranged according to a certain geometric shape and fixed on the ground or insulation board, and finally poured 50mm thick concrete as the filling layer. Other decoration works on the ground can only be carried out after the concrete is dry (usually about 10 days). This kind of laying has the disadvantages of long construction period, high labor intensity of construction personnel, and slow heat transfer of the cement layer, which often leads to high temperature near the heating water pipe, low temperature far away from the heating water pipe, and uneven temperature of the ground. Moreover, the construction operation procedure is complicated. After curing and forming, once the water pipe is aged or broken, it is not easy to move and repair. At the same time, the initial investment of this laying method is relatively high; the laying layer is thicker, which wastes the space of the floor height and increases the structural load of the slab.

Utility model content

The purpose of this utility model is to overcome the shortcomings of the prior art that the wet type is a landfill type project, to provide a single structure, convenient laying, light and thin itself, and good heat preservation effect, which is suitable for dry splicing, assembly, laying, easy disassembly, repair, movement and The ground radiation cooling and heating module for secondary use.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a ground radiant cooling and heating module, including a thermal insulation layer and a heat transfer aluminum plate, which is characterized in that: the thermal insulation layer and the heat transfer aluminum plate are closely bonded and integrated, and the The insulation layer and the heat transfer aluminum plate are provided with grooves, and the two sides of the notch of the groove are facing inwardly, forming an inverted Ω arc-shaped groove. The surface of the heat transfer aluminum plate is provided with a far-infrared radiation coating.

The diameter of the groove matches the diameter of the hot and cold water pipes, and is a 180° curved groove, or a 90° curved groove, or a straight groove, or a combination of grooves.

The far-infrared radiation coating is permeated with nanometer tourmaline powder.

The positive effect of the utility model is that: the connection between the insulation layer and the aluminum plate is firmly bonded together through the viscosity of the polyurethane foam material itself, no other fixing is required, and the hardness of the polyurethane insulation layer is sufficient to withstand the floor and its upper surface. load, so that the thickness of the cooling and heating module is reduced, the quality is reduced, the floor height of the room is saved, and the structural load of the floor is reduced; , so as to clamp the water pipe and connect firmly; the aluminum plate is coated with far-infrared radiation coating, and the far-infrared coating can realize more choices of far-infrared bands by changing the composition or proportion of the coating, which can promote blood circulation, balance pH value, and promote cell activation Regeneration, improvement of disease resistance and other beneficial effects on human health; the modular unit of the utility model can be put into mass production in the factory, dry-laid and assembled on site, without concrete backfill, quickly spliced and formed, and the construction process is simple; once the cooling and heating module fails, it needs to be dismantled It is fast and convenient to repair and move, and can be used for subsequent secondary use. The cooling and heating module of the utility model can be laid solidly or on the ground.

Detailed ways

The structure of the cooling and heating module is shown in Figure 1. It is a ground radiation cooling and heating module, which includes a thermal insulation layer 6 and a heat transfer aluminum plate 7. The layer 6 and the heat transfer aluminum plate 7 are provided with a groove 4, and the two sides of the notch of the groove 4 are buckled inwardly, forming an inverted Ω arc-shaped groove.

The diameter of the groove 4 matches the diameter of the hot and cold water pipes, and the trend is a 180° curved groove 1, or a 90° curved groove, or a straight groove 2, or a combined direction groove 3.

The surface of the heat transfer aluminum plate 7 is provided with a far-infrared radiation coating 8 .

The far-infrared radiation coating 8 is impregnated with nanometer tourmaline powder.

The production method of the ground radiation cooling and heating module:

1. Cut the aluminum plate according to the preset size of the cooling and heating module, put the aluminum plate into a special stamping die, and stamp it multiple times by the stamping machine to form an inverted Ω arc-shaped groove of the specified size;

2. Spray polyurethane foam material on the back of the aluminum plate to form a polyurethane insulation layer. If the temperature in winter is cold, you can preheat the aluminum plate first, and then spray polyurethane foam material. Due to the viscosity of the polyurethane foam material itself, the polyurethane insulation layer and the aluminum plate Closely fit and firmly bonded; then cut and shaped to make the bottom and side of the polyurethane insulation layer flat;

3. Finally, select the far-infrared coating according to the required infrared band, spray the far-infrared radiation coating on the surface of the aluminum plate, and dry it in the shade.

As shown in Figure 2, it can be seen that in application, several ground radiating grooves are composed of 180° curved groove 1, straight groove 2, 90° curved groove, and combined trend groove 3 (combined by straight groove and 90° curved groove in Figure 2). The heating and cooling module units are spliced and assembled, so that the inverted Ω arc-shaped grooves on each unit are naturally connected, the cold and warm water pipes are placed in the inverted Ω arc-shaped grooves 4, and the water pipes are arranged along the grooves 4 to form a circuit, and the grooves 4 The two sides of the notch are buckled inwardly, forming an inverted Ω arc-shaped arc groove, and the water pipe is firmly clamped in the groove 4; the cold and warm water pipes can be PP-R pipes, PERT pipes, PE-X pipes, PB pipes, etc., the hot water in the pipes is used for heating the room in winter, and the cold water in the pipes is used for cooling the rooms in summer. The specific number of modules required for a complete ground radiation cooling and heating module can be determined according to the required laying area.

The preferred laying scheme of the ground radiant cooling and heating module involved in the utility model is to adopt the ground-floating method to lay. The structure is shown in Figure 1. Each module unit makes the aluminum plate 7 on the insulation layer 6 wider than the insulation layer 6 by 20mm on both sides. The module unit is embedded between two adjacent floor panels 5, and the aluminum plates 7 left on both sides are rested on the floor panels 5. This design reduces the load-bearing of the insulation layer 6, and part of the load-bearing transfer is supported by the aluminum plate 7. Certainly the utility model also can be used for actual paving, and the aluminum plate 7 and the insulation layer 6 below it are made into equal width, thereby realizing no ground corrugated 5 laying.
