Control system obtains the condensing pressure of the refrigerant of certain level height.Using the condensing pressure of the level height as base Standard keeps the second valve if level height condensing pressure below keeps the closed state of the second pressing member 182 without decline The open state of door 184.At this point, refrigerant is fed directly to indoor heat exchanger 140 through the second valve 184 by tracheae 112.If The condensing pressure of the level height or more has decline, and when being lower than the second preset pressure, then controls the closing of the second valve 184, Second pressing member 182 is opened.It is pressurizeed by the second pressing member 182 to the refrigerant in tracheae 112, adds refrigerant Indoor heat exchanger 140 is transported to after pressure.The pressure loss for reducing refrigerant in this way, reduces the energy consumption of heat pump unit 100.
When condensing pressure reaches the second preset pressure, the second valve 184 of control is opened, and the second pressing member 182 is closed.? That is after condensing pressure restores, the second pressing member 182 and the second valve 184 with restore original state, i.e. holding the The closed state of two pressing members 182 keeps the open state of the second valve 184.
If condensing pressure continues to decline, 182 persistent pressure of the second pressing member is controlled, until condensing pressure reaches second in advance If pressure.That is, being needed by 182 persistent pressure of the second pressing member, i.e., if the problem of pressure drop of condensing pressure is unresolved The revolving speed of the second pressing member 182 is improved, until condensing pressure is after the zone of reasonableness of setting, then opens the second valve 184, is closed Close the second pressing member 182.
Assuming that be illustrated for ten layers, when ten layers of condensing pressure decline, and nine layers and steaming below condensation pressure Power is normal, ten layers or more of condensing pressure decline.At this point, nine layers and the second pressing member 182 below and the second valve 184 Operating status it is constant, ten layers or more of the second pressing member 182 is opened, and the second valve 184 is closed.Pass through the second pressurization part Part 182 pressurizes to the refrigerant in tracheae 112.When condensing pressure reaches the second preset pressure, the second valve 184 of control is beaten It opens, the second pressing member 182 is closed.If condensing pressure continues to decline, 182 persistent pressure of the second pressing member is controlled, until cold Solidifying pressure reaches the second preset pressure.

In one embodiment, heat pump unit 100 further includes support frame (not shown), is used to support pressure-applying unit 180.Support Frame is external support members, is set at corresponding floor, and corresponding first pressing member 181 and the second pressurization are used to support Component 182 avoids the gravity of the first pressing member 181 and the second pressing member 182 that main connecting tube 110 is caused to fall.
Referring to Fig. 1 and Fig. 9, it is possible to understand that, the first pressing member 181 at runtime, can be due to pressure reduction or confession Liquid measure deficiency leads to the cavitation of the first pressing member 181, i.e. pressure in the first pressing member 181 is lower than liquid refrigerants Evaporating pressure leads to flash gas occur, thus to 181 corrosion phenomena inside of the first pressing member.Based on this, this is practical The heat pump unit 100 of a novel embodiment provides two kinds of settling modes:
One is the abundant degree of supercoolings by refrigerant liquid before guaranteeing into the first pressing member 181.It can drop in this way The probability of low liquid flashes.Principle is can also to be obtained from liquid internal due to the condition of liquid flashes except through reducing pressure Heat obtains, therefore ensure that the sufficient degree of supercooling of liquid refrigerant is can to prevent to flash, optional to avoid cavitating , outdoor heat exchanger 130 further included cold part, crosses cold part and is used to that the refrigerant for entering the first pressing member 181 to be subcooled. It is exemplary, the length of the first heat exchanger components 1312 can be increased to guarantee suitable degree of supercooling.Certainly, the utility model its In his embodiment, it can also be used and increase in outdoor heat exchanger 130 means such as rotation speed of fan flexibly to guarantee suitable degree of supercooling.
Another kind is not stopped by guaranteeing that the suction inlet of the first pressing member 181 goes out refrigerant liquid, that is, guarantees sucking Mouth adequately liquid refrigerants flowing also can avoid cavitation erosion.The utility model is equipped with liquid storage component 190 by the first pressing member 181 To guarantee that the liquid refrigerant of suction inlet uninterruptedly flows.Specifically, heat pump unit 100 further includes liquid storage component 190 and position Controlled valve (not shown) in 190 both ends of liquid storage component, one end of liquid storage component 190 are connected to liquid pipe 111, liquid storage component 190 other end is connected to the entrance of the first pressing member 181, and controlled valve pressurizes for realizing liquid storage component 190 and first On-off between component 181.
Liquid storage component 190 has sufficient liquid at the suction inlet to guarantee the first pressing member 181 for storing refrigerant State refrigerant, so that the liquid refrigerant at suction inlet does not stop, to avoid cavitation erosion.Exemplary, liquid storage component 190 is liquid storage Tank, controlled valve are solenoid valve.One end of liquid storage component 190 is connected with liquid pipe 111, between installation controlled valve control enter storage The refrigeration dose of liquid component 190, the other end of liquid storage component 190 are connected with the suction inlet of the first pressing member 181, between install The control of switch valve gate valve enters the refrigeration dose of the first pressing member 181.When heat pump unit 100 is run, liquid pipe is periodically opened 111 guarantee there is refrigerant liquid in liquid storage component 190 with the controlled valve of liquid storage component 190.
When 181 suction pressure of the first pressing member is too low, the switch between liquid pipe 111 and liquid storage component 190 is closed Valve opens the controlled valve between liquid storage component 190 and the first pressing member 181, guarantees the refrigerant in liquid storage component 190 Liquid can continuous influent Pump Suction Nozzle, to avoid cavitating.
