Description
Technical Field
[0001] This utility model relates to the field of ventilation system technology, and in particular to a ground-based all-air system. Background Technology
[0002] Existing patent CN106016540A discloses a method for controlling floor heating and cooling, but in practice, the following shortcomings have been found:
[0003] 1) The underground convex and concave double-layer module causes insufficient return air during air convection, resulting in noise and greater resistance for the fan in the air outlet;
[0004] 2) The inlet water pipes of the underfloor heating system and the surface cooler in the underground air outlet use the same water line. The water temperature is the same when cooling in summer. The low water temperature causes the surface temperature to be too cold. If the water temperature is set slightly high, the air outlet temperature will not be low enough, resulting in a slow cooling speed.
[0005] 3) The inlet and outlet of the underground surface cooler are both on the same side of the metal box at the air outlet. If a leak occurs, the ground must be disassembled for repair.
[0006] 4) During the plum rain season, when the temperature is low and the humidity is high, it is found that the indoor temperature and humidity drop simultaneously when dehumidifying, which seriously affects the comfort level.
[0007] 5) Because it uses a single water temperature principle, it cannot achieve temperature and humidity separation control in the same time period under low temperature and high humidity conditions;
[0008] 6) Automatic humidification is not possible during dry seasons.
[0009] In summary, this application addresses the shortcomings mentioned above and aims to improve upon them. Summary of the Invention
[0010] The technical problem to be solved by this utility model is to provide a ground-based all-air system that increases the underground air flow space and achieves the dual effects of dehumidification of the air outlet equipment and heating of the ground through the dual water distribution unit.

The surface cooler cleaning high-pressure pipe device includes a high-pressure, high-temperature jet nozzle and an air pipe. The side of the air outlet device is equipped with a ventilation opening. The air outlet device is made of PVC vacuum-formed material or metal.
[0016] The U-shaped or straight surface cooler is installed above the square water tank, with its inlet and outlet located on opposite sides of the air outlet unit. A drain tee is fitted to the drain outlet of the square water tank, with a plug installed at one end and the other end connected to the air outlet unit's drain outlet. The fan is installed inside the automatic lifting box of the air outlet unit, which is located on one side. The negative ion generator, humidifier, and aromatherapy diffuser are installed in front of the automatic lifting box. Multiple protruding support columns are evenly distributed inside the air outlet unit to reinforce the top plate's pressure resistance, with space for airflow between them. A high-pressure cleaning device for the surface cooler is installed next to it. Air outlet vents are located on three sides of the air outlet unit. An automatic dustproof sealing device is installed above the automatic lifting box. A ground-level air outlet is installed on top of the automatic lifting box. One end of the humidifier is connected to a humidifying water pipe, and the other end is connected to a water source.
[0017] The return air equipment includes ultraviolet lamps, fans, filters, multiple support columns, and an automatic lifting box. It has ventilation openings on three sides and is made of PVC vacuum-formed material or metal.

The three sides of the return air equipment are equipped with return air equipment ventilation openings.
[0019] The fresh air equipment includes a small fan and a filter, and the material of the fresh air equipment is ABS or metal.
[0020] The fresh air equipment is equipped with a small fan and a filter. One end of the fresh air equipment is fixed by a duct cap through the wall, and the other end is connected to one side of the air outlet equipment by a duct. It is installed on the bottom of the floor decoration material or on the wall. The movable floor panel is installed above the small fan as an access panel for maintenance.
[0021] The cold and heat source host, circulating pump, first water manifold, second water manifold, solenoid valve, mixing center chamber, fan, negative ion generator, humidifier, aroma diffuser, ultraviolet lamp, fan, heating water tank, automatic dustproof sealing device for air outlet, automatic lifting box for air outlet equipment, automatic lifting box for return air equipment, and central controller control the system components through a temperature controller and a 485 communication line combined with a power control box.
[0022] The central controller receives instructions from the temperature control panel and controls the water supply to the underfloor heating pipes and the water supply to the surface cooler in the air outlet equipment. The temperature control panel is a controller for controlling temperature, humidity, fan, negative ion generator, aromatherapy, ultraviolet lamp, fresh air, automatic lifting box, and dustproof device at the air outlet.
[0023] The underfloor heating pipes are installed on the hook-type underfloor heating pipe installation module. When the underfloor heating pipes transport cold or hot water, the underground air undergoes a temperature change, turning the entire underground area into a large heat exchanger. The fan in the air supply unit blows underground air into the room, while the fan in the return air unit blows indoor air into the underground. When the fans in the air supply and return air units operate simultaneously, the air supply and return air units facilitate thorough exchange between underground and above-ground air through the space within the hook-type underfloor heating pipe installation module, or create air convection through ventilation ducts. This air convection achieves cooling or heating effects. Negative oxygen ions, water mist from the humidifier, and fragrance from aromatherapy are all delivered into the room by the fan in the air supply unit, improving indoor air quality.
[0024] This application includes a heating water tank. In a high-humidity and low-temperature environment, a first manifold connected to the air outlet equipment and a second manifold connected to the underfloor heating pipes operate in a high-temperature and low-humidity environment. The second manifold is supplied with water from the heating water tank and then delivered to the underfloor heating pipes. Under the control of the inter-controller, the two manifolds achieve the dual effects of dehumidifying the air outlet equipment and heating the floor, thus achieving constant temperature and humidity, independent temperature and humidity control, and the effect of separate indoor temperature and humidity control.
[0025] This application features a dual-temperature water control mode. The cooling medium in the air outlet unit is supplied by low-temperature water via the pipes of the first manifold. The mixing center converts the low-temperature water into medium-temperature water, which is then supplied to the underfloor heating pipes of the second manifold. During summer cooling, when indoor air enters the ground, the underfloor heating pipes supplying the medium-temperature medium initially cool the air. The underground air then flows to the low-temperature cooling unit in the air outlet unit, where it is further cooled before being delivered indoors through the vents. This achieves a rapid drop in indoor temperature while preventing the floor temperature from becoming too low, thus improving comfort. During heating, both manifolds simultaneously supply high-temperature hot water, achieving a dual effect of heating the air through underfloor heating. In low-temperature and high-humidity environments, the two manifolds supply water at different temperatures: the first manifold supplies chilled water for dehumidification, while the second manifold supplies hot water for underfloor heating, preventing excessively low indoor air temperatures.
[0026] The air supply equipment, return air equipment, fresh air equipment, underfloor heating pipe installation module with hook, and insulation board are all hidden at the bottom of the floor decoration material.

The solenoid valve ensures that both water tanks are filled with either cold or hot water at the same time, or one tank contains cold water and the other contains hot water.

The mixing center chamber 5 converts the low-temperature water into medium-temperature water for supplying the underfloor heating pipes 45 of the second manifold. During summer cooling, when indoor air enters the ground, the underfloor heating pipes supplying the medium-temperature medium initially cool the air. The underground air then flows to the low-temperature surface cooler 14 in the air outlet device 11, where it is further cooled before being delivered indoors through the vents. This achieves a rapid drop in indoor temperature while preventing excessively low floor temperatures, thus improving comfort. During heating, both manifolds simultaneously supply high-temperature hot water, achieving a dual effect of heating the air through underfloor heating. In low-temperature and high-humidity environments, the two manifolds supply water at different temperatures: manifold A7 supplies chilled water for dehumidification, while manifold B6 supplies hot water for underfloor heating, preventing excessively low indoor air temperatures.
