Description

Technical Field

[0001] The invention relates to the technical field of HVAC systems, and in particular to a HVAC system. Background Art

[0002] Heating system is a necessary system facility for all rooms in the world when the temperature is below 10~15℃. Hot water circulation heating system is one of the most commonly used ways to feel comfortable, which dominates the heating system. All water heating systems are composed of three parts: 1. Heating device that heats water with different heat sources. 2. Control device that controls water temperature, water circulation and indoor temperature. 3. Heat dissipation device that dissipates the heat of water into the room.

[0003] Heating sources are divided into two categories according to the type of energy: gas heating and electric heating. Electricity is the most popular energy source in the world, and electric heating furnaces that use electric heaters to heat water are also the most widely used.

[0004] As for electric heating furnaces, although different manufacturers design and produce different products, they are all composed of the following: heating furnace box, electric heater, circulating water pump, development water tank or expansion water tank, temperature sensor, thermostat, control component box, power circuit breaker and other parts or all devices. Even the most integrated electric heating furnace has all these devices. To form a complete heating system, it must also be equipped with a distribution and collector and inlet and return pipes to achieve floor radiation heating. When installing the heating system in the customer's home, various water heating pipes must be assembled and connected on site. The disadvantages are: 1. Increase the working time, workload and construction cost of on-site installation and construction. 2. Increase the cost of connecting water heating pipes. 3. The appearance is messy and occupies a large space. If you want to be neat and beautiful, you must make an overall closed decoration for each heating device, which will incur additional decoration costs. 4. The extension of the connection water heating pipes will inevitably cause heat loss and energy waste. 5. The scattered exposure of some components will inevitably increase the failure rate of the heating system. Summary of the invention

[0028] The structure of the present invention is a plastic plate profile specially developed for indoor radiant cooling and heating, with multiple water channels inside for water to flow. When the plate is laid on the ground and equipped with relevant sealing accessories, hot water can be circulated in the plate with multiple water channels to dissipate heat for heating or cold water can be circulated to dissipate cooling and reduce indoor temperature. The plate described in this solution can also be installed on walls and ceilings for decoration, insulation and sound insulation.

[0029] In the structure of the present invention, the plates can be spliced ​​in a variety of ways. They can be connected and fixed in the length direction by docking pieces, and can be placed side by side in the width direction or connected in the middle by existing clamping methods. The details are not repeated here. The water channel part of the plate can be connected in parallel horizontally and extended in any direction to realize sealed and pressure-resistant water circulation, as follows: A. When the butt joint is extended: a. Cut the plate profile horizontally at 90° perpendicular to the forward direction. b. Place the sealing gasket on the water-permeable plate butt joint 203. c. Use pan head flat tail self-tapping screws to install and fix the sealing gasket and the water-permeable plate butt joint on the neat horizontal end surface of the plate profile. d. Install the sealing ring on the butt pipe of the water-permeable plate and insert it into the round holes of the butt joint installed on the two water-permeable plates to be butt jointed. e. Place the water-permeable plate butt joint fixing plate in the fixed position on the two butt joints, and install and fix the butt joint fixing plate with countersunk flat tail self-tapping screws.

[0030] B. When connecting in parallel horizontally: a. Cut the plate profile horizontally at 90° perpendicular to the forward direction. b. Place the sealing gasket on the water-passing plate water-collecting part. c. Use the pan head and flat tail self-tapping screws to fix the sealing gasket and the water-passing plate water-collecting part on the neat horizontal end surface of the plate profile. d. Use the connecting water pipe to insert the two water-passing plate water-collecting parts equipped with the water pipe sealing kit to complete the horizontal parallel connection.

[0031] C. Classify the interconnecting water pipes according to the water inlet and water return, and then connect them to the heating furnace. Finally, lay the selected decorative surface layer on the several water-permeable panels assembled by the above splicing method.

[0032] It should be noted that the electric heater in this solution is an existing product with dual channels, and the corresponding electrical connection method and other structures not described in detail in this solution are all existing technologies.

[0033] This scheme is essentially different from the principle of temperature radiation conduction of fluid in traditional cylindrical water pipes and plate-type water pipes laid on the ground. The temperature of the fluid in the traditional cylindrical pipe is 360° radiation conduction, and its radiation conduction efficiency decreases with the increase of the upward radiation angle. The cylindrical pipe cannot be laid without spacing, so the cold and heat energy that is not radiated upward must be conducted through the filler in the spacing of the laid cylindrical pipe, so most of the energy is consumed and cannot be fully utilized. In this scheme, the temperature of the fluid in the water pipe can almost 100% radiate the cold and heat energy, because the rectangular channels set in the plate-type water pipe allow the fluid to present a fluid flat layer with almost no spacing and parallel to the ground at a vertical distance of 6~10mm (related to the thickness of the ground decoration material) from the ground. The cold and heat energy can be radiated upward efficiently without obstruction. This is one of the principles that the plate-type water pipe laid on the ground saves 50% energy compared to the radiation conduction of the cylindrical water pipe. In addition, when used in ground radiation cooling and heating, the cooling and thermal resistance is very small. The water layer circulating in the water-passing plate is 6~10mm away from the ground surface (related to the thickness of the ground decoration material), and the temperature difference between the water flow temperature and the ground surface is about 4°C. Therefore, low-temperature water (30~35°C) can be used for ground radiation heating in winter, and high-temperature water (29~21°C) can be used for ground radiation cooling in summer.

[0034] In addition, in this solution, all components of the electric water heating circulation heating system are integrated into one chassis, which reduces the heat loss of exposed pipelines and saves energy. The components of each system do not need to be assembled on site, which saves labor and time for installation and reduces construction costs. There are no holes for entering and exiting the pipelines on the top, front, left and right sides of the floor-standing box, and it can also be used for heating and domestic hot water, saving the cost of covering and decoration, and reducing the space occupied by the beautiful appearance. Through one device, the structures and functions such as heating, water distribution, production water and driving pump are integrated, which effectively solves various technical problems and drawbacks of many existing electric water heating circulation heating systems.
