Description

Technical Field

[0001] The utility model relates to an air conditioning device, in particular to an air conditioning device which utilizes an air flow regulating device to recover condensation heat. Background Art

[0002] In the prior art, in the field of high-precision environmental control, the peripheral environment control + high-precision regional environment control method is adopted. The peripheral environment controls the temperature and humidity of the peripheral environment through refrigeration, dehumidification, humidification and heating; the high-precision regional environment controls the temperature and humidity of the high-precision regional environment through refrigeration, dehumidification, heating and humidification. High-precision temperature control: during the dehumidification process, the return air of the air conditioner flows through the evaporator coil, and the cooling capacity of the unit is increased by increasing the refrigerant flow of the evaporator coil to achieve cooling; then the air temperature is reduced to below the temperature at which the humidity reaches the saturation state by further reducing the air conditioning circulation air volume or increasing the air conditioning refrigeration capacity. The excess water vapor in the air condenses into liquid water on the surface of the evaporator and is discharged from the system through the water collection tray and the drain; then the air conditioning condensation heat is recovered and heated to increase the temperature, and the auxiliary electric heating is precisely adjusted to the target temperature to reduce the supply air humidity.

[0003] The disadvantages of the existing technology are: after passing through the evaporator, all the air flows through the heat recovery condenser or the heat recovery water coil, which has large resistance and high energy consumption of the blower; the air conditioning refrigeration system is complex and adopts a double condensation structure, which has a high failure rate and requires a lot of maintenance.

[0004] In traditional high-precision air-conditioning equipment, the heat exchange regulation response of water coils, evaporators, and condensers is slow; during the refrigeration and dehumidification adjustment process, it is necessary to first over-cool / dehumidify and then adjust the output through high-speed response components such as electric humidifiers and electric heating to achieve high-precision control so that the supply air temperature and humidity meet the supply air requirements.

[0005] The existing double condenser heat recovery structure and the water coil with water-fluorine heat exchanger and the refrigerant double coil heat recovery structure are adopted. The refrigeration system of the double condensation structure air conditioner is complex, the control difficulty is high, and the failure rate is high; due to the large heat capacity of the refrigerant coil and the water coil, the heat control inertia is strong, and the response speed is slow. Although some auxiliary electric heating heat is reduced, the condensation heat utilization rate is not high; the air conditioning airflow all passes through the heat recovery coil, which increases the resistance of the air supply fan, the air conditioning fan energy consumption is high, and the energy saving is not ideal. For this reason, there is an urgent need for a constant temperature and humidity air conditioner with a new cooling and dehumidification device to solve the above-mentioned problem of losing one thing while gaining another.

By increasing the air volume ratio entering the ventilation box, the air conditioning heating amount is increased. Conversely, by reducing the air volume ratio entering the ventilation box 12, the air conditioning heating amount is reduced.

[0093] When the air-conditioning system has no heating demand, the air flow regulating device discharges all the condensed hot air to the outside of the ventilation box through the flow distribution device; when the air-conditioning system has heating demand, the air flow regulating device adjusts the air valve or the variable frequency fan through the flow distribution device's electric proportional integral regulation, and realizes continuous adjustment of the air volume ratio entering the ventilation box by adjusting the air valve proportional regulation / fan analog quantity, thereby realizing continuous adjustment of the heating amount and recoverable heat of 0-100%; the waste heat is discharged from the ventilation box through the proportional air valve flowing through the exhaust port.
