Side, that is to say, that in the outlet end of the second condenser, the flow to liquid is controlled, relative in input end to gas flow
It is controlled, this structure can make the small in size of device, and at low cost, it is more accurate to control.
Preferably, first condenser and second condenser are all made of the air-cooled type of cooling.
In the present embodiment, the first condenser and the second condenser are all made of air cooling way, to water resource no requirement (NR), therefore answer
It is wide with range.
On above-described embodiment basis, further, in the entrance of first condenser and going out for the compressor
Solenoid valve 124 is equipped between mouthful.In this implementation, when user needs lower leaving air temp, by solenoid valve 124 by reheating portion
Divide and close, also just close the first condenser, stops making fresh air dehumidifier is more convenient to make to indoor air heating is entered and left
With, the switch of solenoid valve can be controlled by controller, it is user-friendly.
On above-described embodiment basis, further, the outlet of first condenser and the first flow are adjusted
Check valve 125 is equipped between element, the check valve 125 is described first-class for flowing to liquid by the outlet of the first condenser
Measure the entrance of regulating element.In the present embodiment, check valve can be avoided refrigerant and reversely flow back towards in the first condenser, further ensures and works as
User needs the first condensation when lower leaving air temp to stop working, thus energy saving.
It should be noted that temperature-sensing element 170 and first flow regulating element can by with the control of fresh air dehumidifier
Device communication connection processed, to realize mutual communication connection, same second flow regulating element is connect with controller communication, control
Device controls according to preset indoor temperature and the aperture of flow-regulating components.
Temperature-sensing element 170 is for detecting the temperature for being blown into indoor gas, that is, temperature-sensing element 170 is to fresh air dehumidifier
Gas temperature at air outlet 180 is detected, depending on position is specifically arranged according to specific needs.
Wherein, temperature-sensing element 170 can be arranged independently of each other with first flow regulating element 132, as shown in Figure 1, at this time
The structure type of temperature-sensing element 170 can be a variety of, such as: temperature sensor, thermometer or temperature sensing package etc., first flow tune
Saving element 132 can be the flow-regulating components such as motor-driven valve, solenoid valve or electric expansion valve.
It is also possible that temperature-sensing element 170 and first flow regulating element can integrate and be integrated, that is, heating power expansion valve is used,
Heating power expansion valve be arranged on pipeline, can to the first condenser close to indoor side gas (i.e. for being blown into it is indoor
Gas) it is detected, the flow of the refrigerant of the first condenser can also be controlled.
On above-described embodiment basis, in order to assist entire fresh air dehumidifier to adjust the temperature for entering and leaving indoor gas,
Fresh air dehumidifier may also include the first temperature sensing package, and the first temperature sensing package is for perceiving the refrigerant flowed out from the first condenser 130
Temperature, to trigger the control opening degree adjustment of first flow regulating element；Wherein, when the temperature of the first temperature sensing package perception is lower than default
The opening degree of value, the first expansion valve of control increases；When the temperature of the first temperature sensing package perception is higher than preset value, the first expansion valve of control
Opening degree reduce.
On above-described embodiment basis, further, fresh air dehumidifier further includes the second temperature sensing package, and second flow is adjusted
Element 122 is the second expansion valve, the second temperature sensing package and the second expansion valve communication connection, and the second temperature sensing package is cold from second for perceiving
The temperature of the refrigerant flowed out in condenser 120 is to trigger the control opening degree adjustment of the second expansion valve；Wherein, when the second temperature sensing package perceives
Temperature be lower than preset value, control the second expansion valve opening degree increase；When the second temperature sensing package perception temperature be higher than preset value,
The opening degree for controlling the second expansion valve reduces.
At work, refrigerant passes through the compression of compressor 110, forms the gas of high temperature and pressure, is entering first
Before condenser 130 or the second condenser 120, the temperature of the refrigerant near the first condenser 130 and the second condenser 120 is
It is identical；However refrigerant have respectively entered the first condenser 130 and the second condenser 120 condensation after, from the first condenser
The refrigerant flowed out in 130 is different with the temperature of the refrigerant flowed out from the second condenser 120, thus first flow regulating element
132 and second flow regulating element 122 can be respectively according to the temperature of refrigerant flowed out from the first condenser 130 and from the
Respective opening degree is adjusted in the temperature of the refrigerant flowed out in two condensers 120.
When the temperature of the refrigerant flowed out in the first condenser 130 is higher than preset value, control first flow adjusts member
132 opening degree of part reduces, so that the flow-reduction of the refrigerant of the first condenser 130 is flowed through, so as to reduce the first condenser
130 heating effect, so that indoor temperature is reduced to keep preset temperature；
When the temperature of the refrigerant flowed out in the first condenser 130 is lower than preset value, control first flow adjusts member
132 opening degree of part increases, so that the flow for flowing through the refrigerant of the first condenser 130 increases, so as to improve the first condenser
130 heating effect, so that indoor temperature is increased to keep preset temperature；
When the temperature of the refrigerant flowed out in the second condenser 120 is higher than preset value, control second flow adjusts member
122 opening degree of part increases, so that the flow for flowing through the refrigerant of the second condenser 120 increases, so as to improve the second condenser
120 condensation effect, so that indoor heat is more transmitted to outdoor, so that indoor temperature is reduced to keep default temperature
Degree；
When the temperature of the refrigerant flowed out in the second condenser 120 is lower than preset value, control second flow adjusts member
122 opening degree of part reduces, so that the flow-reduction of the refrigerant of the second condenser 120 is flowed through, so as to reduce the second condenser
120 condensation effect, so that indoor heat is less to be transmitted to outdoor, so that indoor temperature is increased to keep default temperature
Degree.
Wherein, first flow regulating element 132 and second flow regulating element 122 can be all made of electric expansion valve, temperature-sensitive
Packet and expansion valve are arranged independently of each other, and temperature sensing package in the prior art can be set also can be set in pipeline on pipeline,
In the case that temperature sensing package is arranged in pipeline, the precise measurement of the temperature to the liquid in pipeline may be implemented, to realize
According to the opening degree for controlling the accurate detection of the temperature flowed out in the first condenser 130 first flow regulating element 132, root
According to the opening degree for controlling the accurate detection of the temperature flowed out in the second condenser 120 second flow regulating element 122.
It is also possible that first flow regulating element 132 and second flow regulating element 122 can also be used expansion valve and sense
