Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning air supply units, and relates to a high-room energy-saving constant temperature and humidity clean unit system. Background Art

[0002] The high-rise constant temperature and humidity clean room system needs to ensure that the cleanliness level of the constant temperature and humidity room with a height of more than 5 meters and less than 10 meters meets the use requirements. Due to process requirements, the room needs a certain height of operating space, and the process environment must meet the requirements of temperature, humidity and cleanliness. When the existing constant temperature and humidity clean room system was implemented, it was found that the air was sent to the room through the primary efficiency, medium efficiency, surface cooling, heating, humidification and high efficiency filter. Due to the wind speed limit of the terminal air supply orifice plate, the room formed a vortex, which could not guarantee the temperature, humidity and cleanliness requirements of the personnel operating surface of the high-rise room. Therefore, it is necessary to develop a high-rise energy-saving constant temperature and humidity clean room system that overcomes the above problems. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies in the above-mentioned background technology and to provide a high-room energy-saving constant temperature and humidity clean unit system in order to meet the customer's requirements for the process environment. The end of the air supply duct is a spherical rotating air supply outlet. The high-speed freely rotating air supply wind speed enhances the circulation of the ventilation times in the room, and the air flow in the room cannot form a vortex. It meets the air supply wind speed in high rooms above 5 meters and below 10 meters, that is, the temperature, humidity and cleanliness requirements of the staff on the operating surface, and comprehensively improves the comfort of the staff and the process requirements for the environment.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a high-room energy-saving constant temperature and humidity clean unit system, including a combined air-conditioning unit; the air outlet at the end of the combined air-conditioning unit is connected to the spherical rotary air supply outlet through an air supply duct, the front end of the combined air-conditioning unit is respectively connected to the return air duct and the fresh air duct, the other end of the return air duct is connected to the return air cavity, the combined air-conditioning unit includes a shell, a fresh air section, a primary filter section, a medium filter section, a surface cooling coil, a heating coil, a humidification section, a fan section, a high-efficiency filter section, and an air supply section are sequentially arranged in the shell; the spherical rotary air supply outlet is arranged at the top of the controlled room, and a return air louver is arranged at the bottom of the controlled room, and the outlet of the return air louver is connected to the return air cavity.

[0005] A primary filter is arranged in the primary filtration section, a medium filter is arranged in the medium filtration section, a wet film humidifier is arranged in the humidification section, a fan is arranged in the fan section, and a high efficiency filter is arranged in the high efficiency filtration section.

[0006] A new return air electric valve is arranged on the fresh air section.

[0007] The primary filter section, the medium filter section and the high filter section are all equipped with a differential pressure switch for detecting the differential pressure.

[0008] A plurality of spherical rotary air supply outlets are arranged in the controlled room, each spherical rotary air supply outlet is connected to the air supply duct through an air supply branch duct, and a pressure difference sensor is arranged at each spherical rotary air supply outlet.

[0009] A pressure sensor A is arranged on the air supply duct.

[0010] A wet film humidifier electric valve is provided at the bottom of the wet film humidifier.

[0011] Temperature sensor B and humidity sensor are installed on the return air duct.

[0012] A temperature sensor A is arranged adjacent to the heating coil.

[0013] The bottom of the surface cooling coil is respectively connected to a cold water inlet pipeline and a cold water outlet pipeline.

[0014] The bottom of the heating coil is respectively connected to a hot water inlet pipeline and a cold water outlet pipeline.

[0015] The system is also equipped with a control cabinet, in which a PLC control system is arranged.

[0016] The working principle of the existing conventional combined clean system: the air passes through the primary filter, first filtering the 5μm~10μm dust particles, then passes through the medium efficiency filter for secondary filtration of the 1μm~5μm dust particles, then passes through the surface cooling section for cooling and dehumidification, the heating section for heating, and the heating section for humidification, and finally the clean air with temperature and humidity meeting the requirements passes through the fan flow section to the end of the room. The high-efficiency filter filters the 0.3μm~0.5μm dust particles and then sends the clean air into the room through the air supply orifice plate. The dust particles and bacteria in the room are brought to the primary filter section of the unit through the return air outlet of the return air sandwich wall and filtered again. This reciprocating cycle achieves a cleanliness and temperature and humidity control of the room. Due to the wind speed limit of the end air supply orifice plate, a vortex is formed in the room, which cannot guarantee the temperature, humidity and cleanliness requirements of the personnel operating surface in the high-rise room, and the high-efficiency filter is set in the room, which often causes failures. It requires an overall investigation, which is time-consuming and labor-intensive.

[0017] The working principle of the high-room energy-saving constant temperature and humidity clean unit system of the utility model is as follows: the air passes through the primary filter to first filter the dust particles of 5μm to 10μm, and then passes through the medium-efficiency filter to filter the dust particles of 1μm to 5μm for the second time, and then passes through the surface cooling section for cooling and dehumidification, the heating section for heating, the humidification section for humidification, the fan flow equalization section, and the high-efficiency filtration section in the unit in turn, and finally the clean air with the temperature and humidity meeting the requirements is sent to the room through the spherical rotary air supply port in the room. The upper end of the spherical rotary air supply port is provided with an electric actuator solenoid valve, which senses the temperature in the room through the temperature sensor and the pressure sensor feedbacks the pressure to adjust the rotation angle and the opening angle of the spherical nozzle, and the dust and bacteria in the room are brought into the primary filtration section through the return air port of the return air wall, and such a reciprocating cycle is achieved to achieve the cleanliness and temperature and humidity control of the room.

[0019] 1. The high-room energy-saving constant temperature and humidity clean unit system provided by the utility model ensures the room requirements of the process environment of large space and high space.

It is simple and easy to operate, reduces the risk of high-altitude operations when replacing filters in high-altitude rooms, reduces the number of filters to be replaced, and saves manpower and material investment costs.
