Description
Technical field
The present invention relates to a kind of air-conditioning system, particularly a kind of air source split-type combined digital compressor capability-variable heat pump hot water air-conditioning system.
Background technology
A main feature of air source split-type combined digital compressor capability-variable heat pump hot water air-conditioning system is along with variation of ambient temperature main frame refrigeration or heating capacity dynamic adjustments, the output of cold and hot amount can so just reach comfortable purpose of energy saving according to the variation user's of indoor load changes in demand.The main frame varying capacity generally has dual mode:
First kind of varying capacity mode is the frequency conversion mode; change the cooling and warming ability that compressor rotary speed changes the suction tolerance of compressor and then changes main frame by changing supply frequency; the shortcoming of this mode is that DC frequency-changing or AC frequency conversion all will adopt frequency-changeable compressor and frequency converter; we know that frequency converter mainly is to change supply frequency by power electronic devices unit commutation inversion; the caloric value of frequency converter is bigger in the process of frequency conversion; the caloric value of this frequency converter derives from the consumption of electric power; the own consumed power of frequency converter about 10%; the present situation of area, Shanghai office building generally is that floor height is higher; office building distributes and compares comparatively dense; can cause like this summer the user all when using air-conditioning intensive relatively heat removal issue more outstanding; the position heat of often placing off-premises station can not discharge rapidly adds the hot stack of floor under sun direct projection; the operating temperature of off-premises station is very high; often will reach 60 spends even spends to 70; the general operating temperature that requires of frequency converter is below 50 degree; so just be easy to occur the heat protection; the form of expression is exactly disorderly closedown; adopt the electric control system complexity of frequency conversion mode in addition; easily break down; easy-maintaining not; easily need change frequency-variable module, later period maintenance cost height.The air-conditioning system that adopts the multi-joint machine in air source of day present technique substantially all is to adopt this technical scheme.
Second kind of varying capacity mode is to adopt digital compressor scheme, digital Compressor Technology is a kind of compressor variable capacity technologies that ancient wheel company introduced to the market August calendar year 2001, its core technology is a pair of whirlpool dish of air-breathing type of cooling screw compressor, one air cavity is arranged at the quiet dish top of top, the bypass pipe of this air cavity by a charged magnet valve links with the air-breathing low-pressure cavity of compressor, when magnetic valve is in conduction position, quiet dish top air cavity is low-pressure state, this moment during compressor operating quiet dish since pressure use and move one millimeter, can not form effective compression chamber between Moving plate and the quiet dish, the invalid compression of boil down to of this moment, also claim the pneumatics contracting, compressor this moment can not suction and discharge, input current is 10% of rated value, when the bypass pipe magnetic valve is in closed condition, quiet dish top air cavity moment becomes high pressure, under the effect of gravity, quiet dish moves down one millimeter, and with the Moving plate close fit, this moment, boil down to compressed at full capacity, also claim effectively compression, be the specified suction tolerance of compressor, this moment, input current was 100% of rated value, regulated the time ratio of bypass pipe magnetic valve break-make, just can regulate the suction tolerance of compressor continuously, closely regulate the capacity of compressor.The advantage one of this compressor variable capacity technologies is that control mode is simple, the 2nd, there is not the existence of harmonic components.The shortcoming of this compressor variable capacity technologies is: the one, and the life-span of compressor requirement is 20 years, and this technology just emerges, and the digital scroll compressor that frame for movement is very complicated does not also carry out the test of reliability through the enough time at present; The 2nd, compressor all is rotation at a high speed as before in any case, consumption with respect to frequency conversion mode energy is apparent, as everybody knows, the large-scale Lodz blower fan of cement industry, mode of speed regulation changes air quantity for making blower fan by fluid-flywheel clutch with motor moment connection or throwing off the earliest, and motor is rotation at a high speed all the time, and this mode is similar with the regulative mode of digital compressor, for various reasons, the back is replaced by the frequency-variable electronic mode of speed regulation; The 3rd, the regulative mode of digital compressor is the moment loading and unloading of compressor, and being changed to of electric current 10% and 100% changes alternately, for electrical network, countless inductance and capacitive means are arranged, the current capacity of a plurality of objects increases severely and subtracts in wink, and the eddy current that causes and heating can be unfavorable to electrical network facilities.
