Abstract

The utility model provides a constant-temperature constant-moisture air processing machine set. A draught fan, a filter, a refrigerating water coil pipe, a refrigerant evaporator coil pipe and a refrigerant condenser coil pipe are arranged inside the cabinet in turn. After air is filtered, the air firstly exchanges heat with the refrigerating water coil pipe for cool-down and dehumidification processing and then has further cool-down and dehumidification by the refrigerant evaporator coil pipe. In the process of cooling down, partial moisture is removed in a condensing way. The utility model realizes the adjusting and control of temperature, utilizes the waste heat emitted from the condenser coil pipe to heat after dehumidification, reaches the needing temperature and realizes the adjusting and control of air temperature. The utility model has high control precision so as to realize lower humidity content of blast. And the utility model has less energy consumption, simple structure and convenient installation, being applied to industrial places or other places which is strict in air humidity and temperature.

Description

Constant temperature and humidity air-treatment unit

Technical field

The utility model relates to a kind of constant temperature and humidity air-treatment unit.

Background technology

Constant temperature and humidity air-treatment unit is used for some production place or other places of air humidity and temperature being had strict demand more, its basic technology route is the air cooling-down dehumidifying after will filtering earlier, heat temperature raising is realized the control requirement to the air constant temperature and humidity thus again.

Traditional constant temperature and humidity air-treatment unit can be divided into two classes according to its processing mode, one class is to adopt refrigerant directly to evaporate to carry out cool-down dehumidification, its structure as shown in Figure 3, this unit comprises that two ends are respectively equipped with inlet and outlet 1.1,1.2 wind cabinet 1, be provided with the air-supply arrangement that mainly constitutes successively by the air intake direction in the wind cabinet by blower fan 11, the main filter that constitutes by filter 2, the main reheat machine that constitutes the cool-down dehumidification device and mainly constitute by refrigerant evaporator coil pipe 4 by hot coil 13 again, air is under the effect of blower fan 11, enter the wind cabinet by air inlet, the process filter is removed dust wherein earlier, pass through the evaporator coil cool-down dehumidification again, reach desired water capacity, be heated to desired temperature through hot coil more then, the advantage of this structure: the one, in the cool-down dehumidification process, air themperature can be dropped to lower, therefore the water capacity of air-supply is also just lower, the 2nd, again hot coil can utilize refrigerant condenser coil 6 waste heat as thermal source, to save energy consumption; Its shortcoming is because normally switch control of compressor needs a period of time when compressor start or operation, so control accuracy is lower; The cool-down dehumidification device that the difference of another kind of structure and said structure mainly shows as wherein is made of chilled water coil pipe 3, its structure as shown in Figure 2, this chilled water coil pipe adopts the chilled water of central cooling that air is carried out cool-down dehumidification, behind the cool-down dehumidification again by hot coil 13 heat temperature raisings again, its advantage is to realize high control precision by the continuous adjusting to chilled water, shortcoming one is that the chilled water supply and return water temperature of central cooling is generally 7/12 ℃, and the water capacity of air-supply is higher; The 2nd, the required energy of hot coil all requires to be unfavorable for saving the energy by the outside input again.

The utility model content

For overcoming the above-mentioned defective of prior art, the utility model provides a kind of constant temperature and humidity air-treatment unit, this air-treatment unit gets up the advantages of existing two kinds of constant temperature and humidity air conditioning processing methods, its operating mode is stable, the control accuracy height, can realize lower air-supply water capacity, and the energy that consumes is few.

The utility model realizes that the technical scheme of above-mentioned purpose is: a kind of constant temperature and humidity air-treatment unit, comprise that two ends are respectively equipped with the wind cabinet of inlet and outlet, be provided with air-supply arrangement successively by the air intake direction in the wind cabinet, filter, cool-down dehumidification device and reheat machine, described air-supply arrangement mainly is made of blower fan, described filter mainly is made of filter, described cool-down dehumidification device mainly is made of chilled water coil pipe that is positioned at the front and the refrigerant evaporator coil pipe that is positioned at the back, described reheat machine mainly is made of hot coil again, the water inlet pipe and water outlet pipe of described chilled water coil pipe can connect the chilled water pipeline of central cooling, and described hot coil again can adopt described refrigerant condenser coil.

Because cool-down dehumidification device of the present utility model is provided with chilled water coil pipe and refrigerant evaporator coil pipe simultaneously, air at first is frozen the water coil cool-down dehumidification, absorb its required most of heat of emitting by chilled water, and the air themperature that enters follow up device regulated accurately, the refrigerant evaporator coil pipe is able under stable operating mode the further cool-down dehumidification of air, realize the low water capacity requirement of air-supply, also reduced simultaneously the power of required refrigerant evaporator, equipment investment and maintenance cost have been reduced, in addition the refrigerant condenser coil is used as the hot coil again of reheat machine, the used heat that makes heat temperature raising can all rely on condenser coil to distribute basically, reduce energy consumption significantly, and simplified device structure.
