Abstract
The invention provides a machine set. An outdoor processing unit heat exchanger consists of two parallel condenser tubes; and a supercooler is positioned between the two parallel condenser tubes of the outdoor processing unit heat exchanger. The refrigeration/heat cycle of the machine set is as follows: in a working condition of refrigeration, a refrigerant is condensed and supercooled, and then sent to an indoor air supply unit heat exchanger for heat exchange, and finally returned to a compressor, and the whole refrigeration cycle process is completed; and in the working condition of heating, the refrigerant is sent to the indoor air supply unit heat exchanger for heat exchange through the compressor, enters the supercooler for supercooling, enters the outdoor processing unit heat exchanger, and finally is returned to the compressor, and the whole heating cycle process is completed. Because the refrigerant is supercooled after a reservoir, the problem of lowering the supercooling degree is solved; because the supercooler is positioned between the two parallel condenser tubes of the outdoor processing unit heat exchanger, a strong airflow field formed on the middle part of a fan can be effectively utilized, and the actual supercooling effect of the system can be improved; and because of big suppercooling degree of the system, the operating stability and reliability of an expanding valve are improved, and the refrigerating capacity and the refrigerating energy efficiency of the system are also improved.
Description
Technical field:
The present invention relates to a kind of brand-new wind air-treatment unit, is a kind of big supercooling degree completely fresh wind air-treatment unit specifically.In this system, cold-producing medium enters the subcooler that is positioned at outdoor processing unit heat exchanger middle part then earlier through the high pressure reservoir.System can stablize and realizes effective cold excessively more than 8 ℃, and this helps the steady operation of expansion valve, improves system's refrigerating capacity, improves the Energy Efficiency Ratio of system.Belong to the Building Environment and Equipment Engineering technical field.
Background technology:
At present, directly the brand-new wind air-treatment of the vaporation-type unit overwhelming majority does not have supercooling apparatus, and the small part system layout has subcooler, often owing to the position of subcooler, has influenced the cold effect of mistake of system's reality greatly yet.Can bring a series of problem like this, such as the expansion valve job insecurity, refrigeration efficiency is not higher than (EER), and refrigerating capacity is not enough etc.These all influence the result of use of the brand-new wind air-treatment of direct vaporation-type unit to a certain extent.
Summary of the invention:
The present invention be directed to the defective that prior art exists,, help the steady operation of expansion valve, improve system's refrigerating capacity, improve the Energy Efficiency Ratio of system, proposed a kind of big supercooling degree completely fresh wind air-treatment unit in order to improve the operating condition of unit.In this system, cold-producing medium enters the subcooler that is positioned at outdoor processing unit heat exchanger middle part then earlier through the high pressure reservoir; System can stablize and realizes effective cold excessively more than 8 ℃ can effectively increasing system's degree of supercooling, improves the self-operating operating mode; Improve refrigerating capacity, improve system's refrigeration efficiency than (EER).
The present invention is for realizing the designed big supercooling degree completely fresh wind air-treatment unit of goal of the invention, and its structure comprises compressor, four-way change-over valve, outdoor processing unit heat exchanger, reservoir, subcooler, expansion valve (choke valve) and indoor blowing unit heat exchanger.Outdoor processing unit heat exchanger is made of two parallel condenser, and subcooler is positioned in the middle of two parallel condenser of outdoor processing unit heat exchanger.Described compressor is connected to outdoor processing unit heat exchanger and indoor blowing unit heat exchanger respectively through behind the four-way change-over valve; Outdoor processing unit heat exchanger is connected via reservoir, subcooler, choke valve and indoor blowing unit heat exchanger.Its refrigeration/thermal cycle is as follows:
Under the cooling condition, cold-producing medium process compressor is by extremely outdoor processing unit heat exchanger (be condenser this moment) condensation of four-way change-over valve, enter reservoir then, cold excessively to subcooler again, and send into indoor blowing unit heat exchanger (this moment for evaporimeter) heat exchange by choke valve, last cold-producing medium is back to compressor once more by four-way change-over valve, finishes whole kind of refrigeration cycle process.
Under the heating condition, cold-producing medium process compressor is by extremely indoor blowing unit heat exchanger heat exchange of four-way change-over valve, enter reservoir then, cold excessively to subcooler again, processing unit heat exchanger outside the choke valve inlet chamber then, last cold-producing medium is back to compressor by four-way change-over valve once more, finishes the whole cyclic process that heats.
The present invention has following beneficial effect with respect to prior art:
1, cold-producing medium was realized coldly after reservoir, effectively solved traditional cold-producing medium and crossed and enter reservoir again after cold, the problem that degree of supercooling reduces.
2, subcooler is positioned in the middle of two parallel condenser of outdoor processing unit heat exchanger, can effectively utilize the powerful air flow field at blower fan middle part, the actual cold effect excessively of increase system.
3, higher system degree of supercooling does not have bubble and exists when guaranteeing cold-producing medium by expansion valve, strengthened the stability and the reliability of expansion valve work.
4, the increase of degree of supercooling has effectively improved the refrigerating capacity of system, has improved the refrigeration efficiency ratio of system
(EER)。
