Description
Technical field
The present invention relates to a kind of variable air rate air-treatment unit, especially a kind of water-cooled refrigerant direct-expansion type variable air rate air-treatment unit.
Background technology
Air conditioning system with variable is to be a kind of air-conditioning system form that purpose grows up with energy-conservation.A kind of form as the all-air conditioning system, because of the indoor quality of system is good, energy-conservation superior performance and air conditioning area control is flexibly during sub-load, become the main flow of world developed country and regional air-conditioning system, be widely used in all kinds of offices, commercial building.
In recent years, along with the raising of China's architectural design standard, air conditioning system with variable is substituting traditional air quantity air-conditioning system of deciding, and progressively obtains promotion and application.
Air conditioning system with variable has all kinds, and they are formed by four essential parts: variable air rate air-treatment unit, air quantity variable end device, air-line system and robot control system(RCS).Variable air rate air-treatment unit is as the element of air conditioning system with variable, also along with obtaining promotion and application.
At present traditional variable air rate air-treatment unit can be divided into two classes according to its processing mode: a class is an air-cooled refrigerant direct-expansion type variable air rate air-treatment unit (being commonly called as roof machine), this series products adopts the direct evaporation of refrigerant to carry out cool-down dehumidification, its operation principle as shown in Figure 3, elder generation's process air cleaner was removed dust wherein after new wind mixed with return air, pass through 4. cool-down dehumidification (heating) of finned refrigerant evaporator again, 6. send by pressure fan then, the advantage of this unit: adopt the refrigerant evaporation cool-down dehumidification to realize cold air distribution easily, the refrigerant system adopts heat pump mode can heat winter, its shortcoming: adopt air cooling energy consumption height, must be installed on outdoor; Another kind of is chilled water type variable air rate air-treatment unit, this series products adopts the chilled water coil pipe to carry out cool-down dehumidification, its operation principle as shown in Figure 4, elder generation's process air cleaner was removed dust wherein after new wind mixed with return air, pass through 1. cool-down dehumidification (heating) of chilled water (hot water) coil pipe again, 2. send by pressure fan then, the advantage of this unit: simple and stable structure is reliable, can realize high control precision by continuous adjusting to chilled water, its shortcoming: refrigeration station must be set in addition, boiler room (heat exchange station) is concentrated provides chilled water, hot water, repeatedly the heat exchange duty loss is big.
Summary of the invention
The technical problem that the present invention solves is: the pluses and minuses of comprehensive above-mentioned two series products, maximize favourable factors and minimize unfavourable ones, provide a kind of water-cooled refrigerant direct-expansion type variable air rate air-treatment unit (include compressor 1., water-cooled condenser 2., heating power expansion valve 3., finned refrigerant evaporator 4., magnetic valve 5., again reheater condenser 6., pressure fan 7., heater 8., casing 9.) it is characterized in that pressure fan air output, water-cooled condenser recirculated cooling water amount, refrigerant compression refrigerating system refrigerant flow all are variable; Solved the direct evaporation type product energy consumption of traditional refrigerant height, can't overcome the big defective of chilled water type product load loss simultaneously, need not refrigeration station to be set, saved the piping shaft space at interior of building in the defective of indoor installation.
