The energy-saving type two-stage dehumidifier is characterized in that the pre-cooling coil pipe, the evaporator, the condenser and the cooling coil pipe are sequentially arranged in the shell, and the pre-cooling coil pipe, the evaporator, the condenser, the cooling coil pipe and the fan jointly constitute an air processing unit; air is pre-cooled and dehumidified by the cooling coil pipe and then enters the evaporator to undergo refrigeration dehumidifying, so that the air processing range of a refrigerating system is reduced, the energy efficiency of the dehumidifier is increased, and the dehumidifying capacity per unit electric quantity is increased; the dehumidified air takes away condensation heat of the refrigerating system after passing through the condenser and is then cooled by the cooling coil pipe, so that the air-blowing temperature is moderate; and the dehumidifier is simple in structure and simple and convenient to install and maintain.
Description
Technical field
The present invention relates to conditioner, is the good energy-saving double-stage dehumidifier of a kind of compact conformation, result of use specifically.
Background technology
Cooled dehumidifier unit in the market mainly is to remove the water in air steam through the direct-expansion type evaporimeter of refrigeration system and the direct positive energy exchange of air, reaches the purpose of dehumidifying.Air themperature after the dehumidifying is lower, and all or part of condensation heat with refrigeration system adds hot-air again, delivers to indoor then.There is following problem in traditional freeze drying: the first, and to remove humidity load and bear by refrigeration system fully, the unit of electrical energy moisture removal is little, function singleness; The second, utilize partial condensation heat to add hot-air, control is complicated; Utilize the air behind whole condensation heat heating and dehumidifications, leaving air temp is higher, increases the air-conditioned room refrigeration duty, causes energy waste.
Summary of the invention
The present invention is directed to the deficiency that exists in the prior art, the cooling of proposition collection, freeze drying are one, the energy-saving double-stage dehumidifier that Energy Efficiency Ratio (COP) is high.
The present invention reaches through following measure.
A kind of energy-saving double-stage dehumidifier; Be provided with casing; Desuperheating coil, evaporimeter, condenser, cooling coil, blower fan, compressor, choke valve, device for drying and filtering are installed in the casing, it is characterized in that desuperheating coil, evaporimeter, condenser, cooling coil in-line arrangement successively are installed in the casing, air conditioner unit of the common composition of desuperheating coil, evaporimeter, condenser, cooling coil and blower fan; Desuperheating coil is to the preliminary precooling cooling of air; Get into the evaporimeter cool-down dehumidification again, reduce the energy consumption of refrigeration system, improve efficiency COP of the present invention.
In the above-mentioned energy-saving double-stage dehumidifier, air flows through desuperheating coil, evaporimeter, condenser, cooling coil successively, and medium is adverse current in air flow and each parts.
The present invention earlier through getting into evaporimeter freeze drying again after the cooling coil precooling dehumidifying, reduces the air-treatment scope of refrigeration system with air, improves unit efficiency COP, improves the unit quantity of electricity dehumidifying effect; Air process condenser after the dehumidifying is taken away the condensation heat of refrigeration system, and through the cooling coil cooling, wind pushing temperature is suitable again, and set structure is simple, and installation and maintenance are easy.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
As shown in Figure 1; A kind of energy-saving double-stage dehumidifier; Be provided with casing 1; Be provided with desuperheating coil 2, evaporimeter 3, condenser 4, cooling coil 5, blower fan 6, screen pack 7, compressor 8, choke valve 9, device for drying and filtering 10 in the casing 1; Characteristic of the present invention be desuperheating coil 2, evaporimeter 3, condenser 4, cooling coil 5 successively in-line arrangement be fixed in the casing 1, they and blower fan 6 be common forms a closed air processing unit, for indoor delivery temperature is suitable, the dry new wind of low humidity; Above-mentioned desuperheating coil 2, evaporimeter 3, condenser 4, cooling coil 5, blower fan 6, screen pack 7, compressor 8, choke valve 9, device for drying and filtering 10 are identical with prior art, and this does not give unnecessary details.
Establish desuperheating coil 2 before the evaporimeter 3, the high-grade low-temperature receiver reduces the process range of evaporimeter 3 to the preliminary cool-down dehumidification of air, dwindles refrigeration system, effectively improves unit efficiency COP, improves the dehumidifying effect of unit quantity of electricity; Air themperature after evaporimeter 3 freeze dryings is lower, heats up through condenser 4 heat absorptions and all takes away condensation heat, does not need extra heat abstractor, and set structure is simple, and installation and maintenance are easy; Air themperature behind condenser 4 is higher, utilizes the high-grade low-temperature receiver to handle to suitable wind pushing temperature through cooling coil 5 again, does not increase the room conditioning load; Desuperheating coil 2 and cooling coil 5 series connection.For strengthening the heat exchange effect, airflow direction becomes countercurrent direction with desuperheating coil 2, evaporimeter 3, condenser 4, cooling coil 5 medium.
Above-mentioned unit is made up of three systems: the air treatment system that desuperheating coil 2, evaporimeter 3, condenser 4, cooling coil 5, blower fan 6 constitute; The refrigeration system that compressor 8, evaporimeter 3, condenser 4, choke valve 9, device for drying and filtering 10 are formed; The water circulation system of desuperheating coil 2 and cooling coil 5 compositions.
The present invention has established desuperheating coil 2 before evaporimeter 3; Pending air is after screen pack 7 at first gets into desuperheating coil 2 and cools; Get into evaporimeter 3 freeze dryings; Low temperature drying air after the dehumidifying absorbs heat to heat up through condenser 4 and takes away condensation heat, handles to suitable wind pushing temperature through cooling coil 5 again.
After the high-grade low-temperature receiver absorbs heat air tentatively lowered the temperature, get into the processing of lowering the temperature of dry air after 5 pairs of intensifications of cooling coil in desuperheating coil 2.
The high temperature and high pressure gas that compressor 8 is discharged gets into condenser 4 heat radiations and is condensed into high-temp liquid, gets into choke valve 9 through device for drying and filtering 10, lowers the temperature into low-temp low-pressure liquid through choke valve 9, gets into evaporimeter 3 heat absorption evaporations, gets into the compressor compresses circulation again.
