Abstract
The utility model discloses a high-efficient energy-saving variable capacitance air conditioning compressor; wherein, at least two compressors with different powers are fixed on a machine base to form a combined machine set, while one-way check valves are arranged on the high-pressure outlet pipes of each branch machine in the combined machine set, and outlet pipes of each one-way check valve are connected as an integration and formed into a common outlet pipeline. The lower ends of each one-way check valve are respectively connected with a return-flow depressurizing electric-control regulating valve and the valve gate of the regulating valve, the valves of each regulating valve are connected with the low-pressure inlet-end pipes of each compressor which are parallelly connected with a low-pressure pipe, a circuit-control plate of the compressors is provided with a power supply-control circuit which is connected with power supply interface ends of each compressor, and a controlling circuit is connected with the return-flow depressurizing electric-control regulating valve. The utility model has the advantages of simple structure, adjustable power in working, high efficiency and energy saving.
Description
Technical field: the utility model relates to a kind of energy-efficient variable capacity air condition compressor.
Background technique:
At present, commercially available general air conditioning compressor has various specifications, and design power all is specified.In the work, no matter load size, the power of operation can't change.Reactive loss is serious like this, and the mechanical wear loss of compressor is big.
Summary of the invention:
The purpose of this utility model is to improve the shortcoming of prior art, and a kind of energy-efficient variable capacity air condition compressor is provided, with power variable, efficient, purpose of energy saving in the realization work.
For achieving the above object, the utility model is taked following design proposal: be fixed on by the compressor of at least two different capacity specifications and constitute a combination unit on the same support, the high-pressure outlet pipe of each extension set is provided with an one way stop peturn valve in this unit, the outer pipe parallel connection of described each one way stop peturn valve is an one, constitute a common outlet conduit, the lower end of described each one way stop peturn valve is connected with the valve of an electronic control mediation valve of backflow step-down and control thereof respectively by pipeline, each mediation valve valve is connected the low-pressure inlet end pipe of each compressor again respectively by pipeline, the low-pressure inlet end pipe of each extension set is connected in parallel on the common low-voltage tube, this low-voltage tube and vaporizer, condenser, the high-pressure outlet pipe of compressor is connected and forms a sealed circulation system.On the compressor circuit control panel power control circuit is housed, be connected each power of compressor interface end, under the control of control centre, according to the size of operating load, select the power of associated compressors, the motor-driven operational system that is combined into a best is carried out work.Other has a control wiring to be connected on the electronic control mediation valve of backflow step-down.Its working principle is, under the high pressure effect of compressor bank, be sealed in the gas of the medium generation High Temperature High Pressure in the air-conditioning system, transfer to condenser by high-pressure outlet end through one way stop peturn valve, cooling has formed the liquid of low-temp low-pressure under the effect of condenser, the evaporator evaporation refrigeration, it is identical with existing air conditioner refrigerating working principle.Load on when compressor bank under the load signal effect of circuit control centre, when selecting compressor operating according to the load size, in order to reduce the starting duty of compressor, the electronic control mediation valve of the step-down that at this moment refluxes will be opened automatically, make compressor be in low-pressure state; When the compressor normal operation, above-mentioned mediation valve is in the extensive next time normal operation position of circuit control, after interior periodic duty of operation of air conditioner, the medium of low-temp low-pressure is under the parallel connection effect of the low pressure pipeline of compressor bank, transfer to each compressor of compressor bank respectively, to guarantee the circular flow work of each compressor.
The utility model is simple in structure, do in adjustable power, efficient height, energy-conservation.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Embodiment:
The utility model is fixed on by the compressor 1,2,3 of three different capacities and constitutes a combination unit on the same support 4.The high-pressure outlet pipe of each compressor of this unit is provided with an one way stop peturn valve 11,21,31, described each one way stop peturn valve 11,21,31 outer pipe parallel connection is an one, constitute a common outlet conduit 5, described each safety check 11,21,31 lower end is respectively by pipeline and the electronic control mediation valve 12 of backflow step-down, 22,32 and the valve 13 of its control, 23,33 link to each other, described conciliation valve 13,23,33 connect the low-pressure inlet end pipe 14 of compressor again respectively by pipeline, 24,34, described each entry end pipe 14,24,34 are connected in parallel on the common low-voltage tube 6.This low-voltage tube 6 is connected with the high-pressure outlet pipeline 5 of vaporizer, condenser, compressor, forms the circulatory system of a sealing.In order to overhaul conveniently, on outlet conduit 5, be provided with a compressor bank maintenance control valve 7.In order to control compressor bank work, on a circuit control panel 8, be connected to compressor bank power control circuit 9 and the electronic control mediation valve of backflow step-down control wiring 10.
