Heat/cold storage type fresh air purifying temperature-regulating combined machine

Abstract

The invention relates to a cold and hot storage fresh air cleaning and adjusting temperature combined machine, characterized in that it comprises all-closed shell and hot storage heat exchanger, air temperature sensor, filter material layer, catalyzing or absorbing material layer, fanner and feed-forward control program, which are installed in turn on the air flow direction; the hot storage heat exchanger comprises refrigerant coil, water storing tank and air flow pipe; the refrigerant coil is set in the water storing tank and inlet-outlet pipes are welt with the wall of water storing tank; electromagnetic valve, thermostatic expansion valve or capillary are set on the inlet pipe of refrigerant out of the water storing tank; the shell of water storing tank is welt with end covers at two sides to form closed tank space; said end covers of water storing tank is also used as pipe plates of air pipes and air flow pipes are welt with pipe plates; liquid irrigation hole, liquid discharging hole and temperature measuring hole are set on the shell of water storing tank; the water temperature sensor is set in the temperature measuring hole.

Description

technical field [0001] The invention relates to air conditioning technology, specifically a heat storage / cooling type fresh air purification and temperature adjustment combination machine used in the air quality control system in the highway toll booth. The international patent classification number is proposed to be Int.Cl.F24F1 / 00 (2006.01) . Background technique [0002] With the rapid development of highway construction in our country, the mileage of various highways is constantly increasing, and the number of matching toll stations is also increasing. The space in the toll booth of the toll station is small, the ventilation conditions are not good, and the air quality in the booth is severely deteriorated. The staff need to work in the toll booth for a long time, which may seriously affect the health of the toll collectors and cause occupational diseases. At present, the highway management department has attached great importance to the air environment quality in the t...

Problems solved by technology

However, application practice and further research have shown that the fresh air purification and temperature adjustment combined machine uses the surface cooler to exchange heat between the refrigerant and the air, and there are deficiencies in the way to adjust the air temperature: according to the operating characteristics of the refrigeration system, the cooling in the coil of the surface cooler The flow of the agent is generally controlled by a solenoid valve. The control strategy is to control the opening and closing of the solenoid valve by measuring the comparison between the fresh air supply temperature and the set temperature, which may lead to severe fluctuations in the supply air temperature, frequent opening and closing of the solenoid valve, and main The frequent start and stop of the refrigerator not only affects the service life of the equipment, but also is not conducive to the thermal comfort requirements of people

Therefore, the design structure and control method of this fresh air purification and temperature adjustment combined machine need to be improved.
