Each air outlet is an independent temperature control area, with built-in mode conversion thermostat, cooling and heating thermostat, actuator and regulating air valve. The air volume can be adjusted according to the set temperature. The opening degree of the regulating air valve is adjusted by the mode thermostat on the air outlet. The return air part enters the return air static pressure box through the open H(1-3) all-steel passage raised floor, and then merges with the return air from the H(3-2) louvered return air inlet through port H(3-4) and returns to the return air duct. Then it returns to the air handling unit through the primary and secondary return air passages. The air supply from the outer zone is delivered to the coupled zone air-conditioned room via the air duct and the replacement air outlets S(5-1) and S(5-2) through the air supply branch S2.

In this invention, after the air is heated, humidified and filtered by the functional sections ① to ⑩ of the air handling device (air handling unit and energy recovery device), the air in the inner area is sent into the air supply static pressure box through the air supply branch port S (1-1). In the return air static pressure box, the near-end secondary return air electric valve H (2-4) mixes the air sent into the air supply static pressure box according to the indoor set temperature, and then sends it into the coupled zone air-conditioned room through the swirl air outlet S (1-2). It enters the return air static pressure box through 1) the all-steel passage floor with opening H (1-3), and then merges with 2) the louvered return air outlet H (3-2) through H (3-4) and then returns to the air handling device through the primary and secondary return air passages.

In this invention, after the air undergoes heat, humidity, and filtration treatment through the air handling unit (air handling unit and energy recovery device) ①~⑩ functional sections, the air in the inner zone is sent into the air supply static pressure box through the air supply S1 branch port S(1-1). In the return air static pressure box, the near-end secondary return air electric valve H(2-4) mixes the air sent into the air supply static pressure box through S(1-1) according to the indoor set temperature, and then sends it into the coupled zone air-conditioned room through the swirl nozzle S(1-2). It then enters the return air static pressure box through the H(1-3) perforated all-steel access floor, and returns to the air handling unit through the H(3-4) return air port and then through the primary and secondary return air passages. The air supply from the outer zone is delivered to the coupled zone air-conditioned room via the air duct and the replacement air outlets S(5-1) and S(5-2) through the air supply branch S2.

The air in the inner zone is supplied to the coupled zone air-conditioned room by the following: 1) the supply air branch S2 through the air duct and the integrated VAV terminal S (3-1); 2) the air is supplied to the supply air static pressure box through the supply air branch port S (1-1), and then the near-end secondary return air electric valve H (2-4) in the return air static pressure box mixes the air supplied to the supply air static pressure box by S (1-1) according to the indoor set temperature, and then supplies the air to the coupled zone air-conditioned room through the swirl nozzle S (1-2); 3) the near-end secondary return air electric valve H (2-4) in the return air static pressure box mixes the air supplied to the supply air static pressure box by S (1-1) according to the indoor set temperature, and then supplies the air to the coupled zone air-conditioned room through the swirl nozzle S (1-2); After the air supplied to the static pressure box by the temperature and S (1-1) is mixed, the air is then mixed with the secondary return air near the H (2-3) of the ground fan-powered terminal and then sent to the coupled zone air-conditioned room through the primary return air passage S (2-1) and then through S (2-2). At this time, the ground fan-powered terminal is not started. Part of the return air static pressure box under the raised floor through the opening H (1-3) passes through port H (3-4) and merges with the return air returning to the return air duct through the louvered return air outlet. Then, it returns to the air handling unit through the primary and secondary return air passages to maintain the set indoor temperature and meet the comfort of the human body and the process requirements of the indoor equipment. The air supply from the outer zone is delivered to the coupled zone air-conditioned room via the air duct and the replacement air outlets S(5-1) and S(5-2) through the air supply S2 branch. After passing through the return air outlet H(5-3), it merges with the return air that has returned to the return air duct and returns to the air handling unit through the primary and secondary return air passages.

In this invention, after the air is treated by heat, humidity, and filtration in the air handling unit (air handling unit and energy recovery device) ①~⑩ functional sections, part of the supply air in the inner zone is delivered to the coupled zone air-conditioned room through the supply air branch S2 branch, branch duct, and integrated VAV terminal S (3-1). Each air outlet is an independent temperature control zone, with a built-in mode conversion thermostat, heating / cooling thermostat, actuator, and regulating air valve. The airflow can be adjusted according to the set temperature, and the opening degree of the regulating air valve is adjusted by the mode thermostat on the air outlet. The supply air is delivered to the supply air static pressure box through the supply air branch S1 branch port S (1-1). Afterwards, the air returns to the return air plenum through the H(1-3) all-steel passage raised floor with openings. It mixes with the air supplied to the supply air plenum by the near-end secondary return air electric valve H(2-4). Part of this mixes with the air entering the coupled zone air-conditioned room through the S(1-2) swirl outlet. The other part passes through the primary return air passage S(2-1) of the ground-mounted fan-powered terminal, mixes with the near-end secondary return air outlet H(2-3) of the ground-mounted fan-powered terminal (with slight heating in winter), is pressurized by the secondary fan, and then sent to the coupled zone air-conditioned room through S(2-2) to maintain the set indoor temperature, meeting the comfort requirements of the human body and the process requirements of the indoor equipment. Another portion of the return air returning to the return air plenum through the H(1-3) all-steel passage raised floor with openings merges with the return air returning to the return air duct through the H(3-2) louvered return air outlet, and then returns to the air handling unit through the primary and secondary return air passages. The air supply from the outer zone is delivered to the coupled zone air-conditioned room via the air duct and the replacement air outlets S(5-1) and S(5-2) through the air supply S2 branch. After passing through the return air outlet H(5-3), it merges with the return air that has returned to the return air duct and returns to the air handling unit through the primary and secondary return air passages.
