Description
Technical field
The utility model relates to a kind of air-conditioning technical, a kind of central air-conditioning of the people especially, and specifically a kind of dispensing head is with the air-cooled pipeline formula air-conditioning unit of restriction.
Background technology
The Centralized Air-conditioning in Public Buildings efficiency is high, energy-conserving and environment-protective, function admirable, easy for installation, reliable and stable, therefore is widely used in the big-and-middle-sized buildings such as various hotels, meeting-place, office building.Central air-conditioning mainly comprises four parts: compressor, condenser, throttling arrangement, evaporimeter, wherein, condenser and evaporimeter can be referred to as heat exchanger, are the equipment of quantity of heat given up or cold.At present, the heat exchanger of main flow central air-conditioning generally adopts finned heat exchanger, and this heat exchanger is provided with many heat exchange copper tubes in inside and heat is handed over fin, and heat exchanger tube is communicated with capillary, capillary collects and is connected to dispensing head, then connects the cold-producing medium delivery main by dispensing head.During refrigeration, liquid refrigerants after throttling first passes through dispensing head and then is assigned to each branch road heat exchanger tube by capillary, then refrigerant evaporation endothermic in each branch road becomes the low-temp low-pressure gaseous coolant and divides and arrive the compressor air suction mouth again through gas, the low-temp low-pressure gaseous coolant becomes the HTHP gaseous coolant after compressor compresses, the HTHP gaseous coolant becomes the high-pressure liquid refrigerant through outdoor heat exchanger, then at the process throttling arrangement, becomes the low-temp low-pressure liquid refrigerants and repeats above-mentioned circulation.Due to distribute number of capillaries numerous when and also refrigerant first through dispensing head, could arrive in each capillary, the dispensing head internal structure that we use at present only has a circular cavity, refrigerant enters by dispensing head that each capillary flow velocity is low, resistance causes greatly each branch road refrigerant maldistribution, cause refrigerant evaporation not exclusively, evaporator area do not take full advantage of, thereby cause that air-conditioning unit refrigerating capacity is less than normal, the usefulness of air-conditioning does not reach desirable state all the time, seriously restricted effective raising of air-conditioner efficiency.
The utility model content
When the utility model makes refrigerant enter each capillary for the connection of existing aircondition dispensing head diameter capillaceous is excessive, flow velocity is low, resistance is large, each branch road refrigerant maldistribution, cause refrigerant evaporation not exclusively, evaporator area do not take full advantage of, thereby affect the problem of air-conditioning unit refrigerating capacity and usefulness, design the air-cooled pipeline formula air-conditioning unit of a kind of dispensing head with restriction.
The technical solution of the utility model is:
A kind of dispensing head is with the air-cooled pipeline formula air-conditioning unit of restriction, comprise indoor set blower fan 1, be placed on the evaporimeter 2 of indoor set blower fan 1 back, evaporimeter 2 is connected by copper pipe with indoor the first stop valve 3, indoor the first stop valve 3 is connected tracheae 4 with outdoor the first stop valve 31 by inside and outside machine and connects, outdoor the first stop valve 31 is connected by copper pipe with gas-liquid separator 5, gas-liquid separator 5 is connected by copper pipe with compressor 6 air intake ducts, compressor 6 blast pipes are connected by copper pipe with condenser 7, 8 runnings of off-premises station blower fan make air pass through condenser 7 heat exchange, filter 9 is connected by copper pipe with condenser 7, filter 9 is connected by copper pipe with throttling arrangement 10, throttling arrangement 10 is connected by copper pipe with outdoor the second stop valve 11, outdoor the second stop valve 11 is connected by inside and outside machine connecting fluid pipe 12 with indoor and outdoor stop valve 112, indoor and outdoor stop valve 112 is connected by copper pipe with evaporimeter 2, the liquid pipe collector of evaporimeter 2 is connected with the separatory capillary by dispensing head 13, the liquid feeding end inside that it is characterized in that described dispensing head 13 is equipped with flow regulator pieces 14.
Be formed centrally the restriction that a diameter is less than dispensing head 13 entrance point diameters in described flow regulator pieces 14.
During refrigerating operaton, the liquid refrigerant of HTHP becomes the low-temp low-pressure liquid refrigerants and enters evaporimeter through the separatory capillary module again after throttling arrangement, in evaporimeter, evaporation endothermic becomes the low-temp low-pressure gaseous coolant and enters compressor through gas-liquid separator, refrigerant after overcompression becomes the HTHP gaseous coolant, the HTHP gaseous coolant becomes the liquid refrigerant of HTHP after condenser condenses, repeats above-mentioned circulation.
The beneficial effects of the utility model are:
The utility model is by the inner restriction that increases of the dispensing head to the separatory capillary module, while making liquid refrigerants after throttling by the dispensing head with restriction, flow velocity increases, resistance reduces, finally allow refrigerant be evenly distributed in each branch road, make to enter the interior refrigerant evaporation of evaporimeter complete, reduce the band liquid measure, thereby give full play to the stability of air-conditioning unit capacity, raising unit operation.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-indoor set blower fan, 2-evaporimeter, the 3-the first indoor stop valve, 31, the first outdoor stop valves, 4-inside and outside machine tube connector tracheae, 5-gas-liquid separator, 6-compressor, 7-condenser, 8-off-premises station blower fan, 9-filter, 10-throttling arrangement, 11-stop valve, 112-indoor and outdoor choke valve, 12-inside and outside machine tube connector liquid pipe, 13-dispensing head, 14-flow regulator pieces.
