Description
Technical field
The utility model belongs to air-conditioner set equipment technical field, and in particular to a kind of energy saving anti-freezing type constant temperature and humidity fresh air
Unit.
Background technique
For some special occasions for generating pollution, such as Animal Lab., hospital infectious disease operating room or the ward ICU,
To avoid cross contamination, air-conditioning system is generallyd use entirely into all fresh air air-conditioning system of full row's mode.It is indoor simultaneously to have again strictly
Temperature and humidity requirement, therefore, air-conditioning system need to be set as constant temperature and humidity Fresh air handling units.Season in summer, constant temperature and humidity Fresh air handling units
The processing task of indoor humidity load is undertaken, which uses traditional way, is sent with chilled water by surface-cooler handle
Wind drops to certain temperature, is cooled down air themperature with the mode of freeze drying, moisture in air is precipitated, humid air is become dry
Dry air, then Cryogenic air is heated to suitable supply air temperature, reach the requirement of constant temperature and humidity.
As shown in Figure 1, constant temperature and humidity Fresh air handling units are in summer, by be located at Fresh air handling units fresh air air inlet 101 it is new
Pressure fan 7 that air-valve 1 drives through motor 6 conveys, through cabinet 10 inside primary filter 2 and the purification of medium effeciency filter 8 after, by
Table is cold/and heating coil 40 carries out cooling and dehumidifying, and it is heated to suitable supply air temperature using heating device or electric heater 41, is passed through
It is sent into air conditioning area positioned at air outlet 102, reaches the water capacity and supply air temperature in air simultaneously and meets humidity load and heat and bear
The requirement of lotus.When winter, to meet the requirement of constant indoor temperature constant humidity, humidifier 5 puts into operation, and table is cold/and heating coil 40 leads to hot water,
Outdoor low temperature and low humidity fresh air through table it is cold/heating coil 40 heat, and by humidifier 5 humidify after blow.
As shown in Fig. 2, constant temperature and humidity Fresh air handling units are in summer, the new air-valve 1 of the fresh wind port 101 by being located at Fresh air handling units
The pressure fan 7 that drives through motor 6 conveys, through cabinet 10 inside primary filter 2 and the purification of medium effeciency filter 8 after, by table it is cold/
Heating coil 40 carries out cooling and dehumidifying, suitable supply air temperature is heated to using heating device or electric heater 41, through being located at
The blow valve 9 of air outlet 102 is sent into air conditioning area, make the water capacity and supply air temperature in air reach simultaneously meet humidity load with
The requirement of thermic load.When winter, to meet the requirement of constant indoor temperature constant humidity, humidifier 5 puts into operation, outdoor low temperature and low humidity fresh air warp
Heating device or electric heater 41 heat, and blow after being humidified by humidifier 5.
The heat and wet treatment of above two constant temperature and humidity unit is typical coupling processing, and entire dehumidification process is surface cooling drop
Warm cooling and dehumidifying needs air dry-bulb temperature dropping to dew point hereinafter, relative humidity can just make close to 100% when very low
Elutriation in air goes out.Meanwhile in order to guarantee suitable supply air temperature, and air is heated to suitable dry-bulb temperature, existed
Very big energy waste, and need heating equipment of additionally increasing input.In addition, when Fresh air handling units are run in winter, due to outdoor new
Air temperature is lower, especially in northern frore area, as shown in Figure 1, if winter table it is cold/heating coil 40 in hot water temperature it is low and flow
When fast very little, along table it is cold/water at low temperature of the tube wall of heating coil 40 is easy to freeze, cause table it is cold/heating coil 40 exists and freezes
Split risk.Especially for as shown in Fig. 2, summer using table it is cold/heating coil 40, winter use electric heater 41 new blower
Group, table is cold/heating coil 40 do not use in winter, if table it is cold/heating coil 40 in do not drain or drain and be not thorough, table
Wind freezes the pipe internal water accumulation of cold/heating coil 40 to the cold, make table it is cold/40 spalling of heating coil, be commonly called as " freeze coil pipe ".

Recyclable device 3 is arranged in recuperation of heat intracavitary 14, and heat recovery apparatus 3 is thermal wheel.Thermal wheel is metal material
The thermal wheel of matter or cardboard material.
Partition air inlet is provided with air inlet by-passing valve, and air-supply by-passing valve is provided at partition air outlet.Air-supply by-passing valve
It is used for air inlet by-passing valve by being not required to the air by heat recovery apparatus 3.Air-supply by-passing valve is for electric control valve or manually
Regulating valve.When selection is using electric control valve, selection uses air-supply bypass Electric air valve 12.Air inlet by-passing valve is electric control valve
Or manual modulation valve.When selection is using electric control valve, selection uses air inlet bypass Electric air valve 13.
Along air supply direction, air duct is divided by former and later two parts using partition, in addition to air inlet bypass Electric air valve 13, air-supply
Peripheral region except bypass Electric air valve 12 and heat recovery apparatus 3 is all sealed up, to guarantee that it is other that all air all pass through air inlet
Logical Electric air valve 13, air-supply bypass Electric air valve 12 and heat recovery apparatus 3.
Below to use the course of work of the energy saving anti-freezing type constant temperature and humidity Fresh air handling units of the utility model to be retouched in detail
State: when summer, high temperature fresh air cools down after heat recovery apparatus, reduce below table it is cold/40 cool-down dehumidification of heating coil required for
Cooling capacity, table is cold/40 cool-down dehumidification of heating coil after condensed water be discharged by condensate water discharging mouth 11, condensed water passes through condensed water
The discharge of discharge outlet 11 belongs to common knowledge to those skilled in the art, and details are not described herein.By table it is cold/heating coil
Low temperature and low humidity fresh air after 40 cool-down dehumidifications heats up after heat recovery apparatus 3, can be energy saving.What heat recovery apparatus 3 recycled
Heat can bypass Electric air valve and 12 by the air-supply of two sides and adjust with air inlet bypass Electric air valve 13.When winter, low temperature is new
Wind carries out temperature energy transmission by heat recovery apparatus 3 and the high temperature fresh air after being heated by electric heater 41, i.e., low temperature side is new
Wind absorbs the temperature energy of high temperature side fresh air, realizes temperature exchange, make to enter table it is cold/after the fresh air of heating coil 40 becomes preheating
Fresh air, new air temperature will not be too low at this time, will not make the table not used it is cold/40 bursting by freezing of heating coil.
Although the foregoing describe specific embodiment of the present utility model, it should be appreciated by those skilled in the art,
Described embodiment is only a part of the embodiment of the utility model, and instead of all the embodiments, these are only to lift
Example explanation, the protection scope of the utility model is to be defined by the appended claims.Those skilled in the art is without departing substantially from this
It, can be to these embodiments under any creative labor of no process under the premise of the principle and essence of utility model
Various changes or modifications are made, but these change and modification each fall within the protection scope of the utility model.
