Embodiment
The utility model is described further below in conjunction with Figure of description.
As shown in figure 1, the air-source carbon dioxide heat-pump system of the present utility model that formula throttling is combined with double capillary
System, including compressor 1, air cooler 2, evaporator 9, air cooler 2 has heat exchange with water inlet, heat exchange delivery port, and evaporator 9 has
There is heat exchange with air inlet, heat exchange air outlet, the heat pump also includes the Combined throttling device 10 of adjustable throttling capacity,
Compressor 1, air cooler 2, Combined throttling device 10, evaporator 9 are successively connected to carbon dioxide according to the flow direction of carbon dioxide
In circulation line.
Especially, Combined throttling device 10 include different capillary A4, capillary B8 and the magnetic valve A5 of throttling capacity,
Magnetic valve C7, capillary A4 and magnetic valve A5 first throttle passage 101 in series, capillary B8 and magnetic valve C7 are in series
Second throttling passage 102, first throttle passage 101 is in parallel with the second throttling passage 102.First throttle passage 101 and second section
It is connected between circulation road 102 on series connection capillary A4, capillary B8 series pipe 103, series pipe 103 and is connected with electromagnetism
Valve B6.
The heat pump also includes regenerator 3, and regenerator 3 has high-pressure channel, low-pressure channel, and high-pressure channel is connected to gas
Between cooler 2 and Combined throttling device 10, low-pressure channel is connected between evaporator 9 and compressor 1.
When unit works, according to the evaporator EAT checked, appropriate is turned on and off each electromagnetism in device
The state of valve realizes the self-control of Combined throttling device 10, is specially：When EAT is too low, magnetic valve is closed
A5, magnetic valve C7, opens solenoid valve B6, longer capillary 4 and the shorter tandem working of capillary 8；When EAT is relatively low
