Abstract
The invention discloses a multi-evaporator parallel energy regulating and energy saving air conditioner which comprises a compressor which can regulate energy, n evaporators, n expansion valves, n minus 1 electromagnetic valves, a condenser and a centrifugal fan and is characterized in that: the n evaporators are connected in parallel, each evaporator is connected with one expansion valve and each evaporator is connected with one electromagnetic valve expect the first evaporator. The technical effects of the air conditioner lie in well solving dry friction of the compressors caused by unfavorable oil return, greatly protecting the compressors, improving the service life of the energy saving air conditioner which utilizes the compressors to regulate energy.
Description
Technical field
The present invention relates to a kind of multiple-evaporator parallel type energy adjusting energy-saving air conditioner.
Background technology
At present, existing air conditioner all only adopts regulate compressors to reach purpose of energy saving, but because unit evaporimeter heat exchange area designs according to peak load, when load is little, compressor can carry out corresponding coupling, output cold still less, at this moment, cold-producing medium reduces, but through evaporimeter the time, because evaporimeter is excessive, the cold-producing medium flow velocity is slack-off, cause compressor lubricant oil not get back to compressor, cause the compressor oil return unfavorable, make compressor produce dry friction and the life-span significantly reduces with cold-producing medium.
Summary of the invention
The object of the present invention is to provide multiple-evaporator parallel type energy adjusting energy-saving air conditioner a kind of, it can protect compressor of air conditioner better, improves the service life of compressor energy adjusting energy-saving air conditioner.
The present invention is achieved like this, but it comprises energy adjustment compressor, n platform evaporimeter, a n expansion valve, a n-1 magnetic valve, condenser and centrifugal blower, it is characterized in that n platform evaporimeter is connected in parallel, connect an expansion valve on every evaporimeter, except that first evaporimeter, connect a magnetic valve on every evaporimeter, but condenser connects the energy adjustment compressor, but the energy adjustment compressor connects evaporimeter, and the evaporimeter next door is connected with centrifugal blower.With the form of a plurality of evaporimeter parallel connections, make evaporimeter and compressor energy adjustment section mate, when the load maximum, the compressor standard-sized sheet is controlled the magnetic valve of each evaporimeter and is all opened, the unit full-load operation, when load hour, compressor carries out energy adjustment, when energy is output as (n-1)/n times of compressor ceiling capacity, closed electromagnetic valve, that is, the evaporimeter shielding, the evaporimeter heat exchange area reduces, make the cold-producing medium flow velocity of process evaporimeter remain unchanged, the compressor oil return is normal.By that analogy, evaporimeter can keep exporting the heat exchange area that energy is complementary with compressor, thereby does not influence the cold-producing medium flow velocity, keeps the compressor oil return normal.
Technique effect of the present invention is; after the evaporimeter segmentation; its heat exchange area can be flux matched with compressor output; flow velocity is constant during cold-producing medium process evaporimeter; the compressor oil return is normal; thereby solved the dry friction that compressor causes because of oil return is unfavorable well, protected compressor greatly, improved such and utilized compressor to carry out the service life of the energy-saving air conditioning machine of energy adjustment.

But 1 energy adjustment compressor 2, condenser 3, magnetic valve 4, expansion valve 5, evaporimeter 6, centrifugal blower in the drawings
The specific embodiment
As shown in Figure 1, but the present invention includes energy adjustment compressor 1, three evaporimeters 5, three expansion valves 4, two magnetic valves 3, condenser 2 and centrifugal blower 6, it is characterized in that three evaporimeters are connected in parallel, connect an expansion valve 4 on every evaporimeter 5, except that first evaporimeter, connect a magnetic valve 3 on every evaporimeter, but condenser 2 connects energy adjustment compressor 1, but the energy adjustment compressor connects evaporimeter 5, and the evaporimeter next door is connected with centrifugal blower 6.Form with three evaporimeter parallel connections, make evaporimeter and compressor energy adjustment section mate, when the load maximum, the compressor standard-sized sheet, controlling the magnetic valve of each evaporimeter all opens, the unit full-load operation, when load hour, compressor carries out energy adjustment, when energy is output as (n-1)/n times of compressor ceiling capacity, one of them closed electromagnetic valve, that is, wherein evaporimeter shielding, the evaporimeter heat exchange area reduces, make the cold-producing medium flow velocity of process evaporimeter remain unchanged, the compressor oil return is normal.By that analogy, evaporimeter can keep exporting the heat exchange area that energy is complementary with compressor, thereby does not influence the cold-producing medium flow velocity, keeps the compressor oil return normal.
