Description
Technical field
The present invention relates to the refrigeration systems that refrigerating field, in particular to a kind of anti-liquid hammer occur.
Background technology
The refrigeration system of freezer is mostly directly evaporated to freezer cooling using refrigerant in the cooling equipment of freezer at present
Refrigeration system, the advantages of this refrigeration system is larger with the refrigerating capacity of the unit mass of refrigerant.But because cooling is set
It is required in standby full of refrigerant, then the refrigerant charge of whole system is larger, and the problem of bringing in this way is：If ammonia system
Cryogen, ammonia are noxious materials, then the danger of entire freezer is larger；If refrigerant is freon, the price of freon is high
High, the construction cost and operation, maintenance cost for making entire freezer are significantly increased.There is directly the feed liquid way of refrigerant at present in freezer
Connect expansion feed flow, gravity force liquid-supply and pump forced circulation feed flow.Shwoot gas when during liquid provision through direct expansion due to refrigerant throttling expansion
Body is more, and cold is less possessed by refrigerant gas, therefore reduces the refrigerating efficiency of cooling equipment.If in addition, cooling
It is not filling refrigerant in equipment, but refrigerating medium, then liquid provision through direct expansion does not just apply to；Gravity force liquid-supply and pump are forced to follow
Flash gas when ring feed flow is because by refrigerant liquid throttling expansion is efficiently separated, and what it is into people's cooling equipment is neat liquid
Refrigerant, therefore the refrigerating efficiency for cooling down equipment is higher, but because pump forced circulation feed flow is more times of feed flows, i.e., set into people's cooling
Standby liquid refrigerant is far longer than evaporation capacity of the liquid refrigerant in equipment is cooled down, and cools down at the liquid refrigerant in equipment
In turbulence state, so the refrigerating efficiency of the refrigerating efficiency force of gravity feed flow of pump forced circulation feed flow is much higher.Pump is forced to follow
Unique shortcoming of ring feed flow is exactly to need to increase liquid pump in systems, that is, adds additional the energy consumption of system.In addition, current is cold
Library achievees the purpose that energy-saving mostly using hot gas defrosting, but there are serious " liquid hammer " risks for hot gas defrosting.If cooling
It is not filling refrigerant in equipment, but refrigerating medium, then the defrosting of warm refrigerant gas is also just inapplicable.

Afterwards, the pressure reduction detected of pressure sensor 21, solenoid valve 23, solenoid valve 13 are closed during less than setting value, solenoid valve 19
It opens.At this moment the pressure that the pressure sensor 22 on 8 water outlet of storage tank detects reaches setting value, and solenoid valve 20 is closed, electromagnetism
Valve 24,14 is opened, the low temperature refrigerating medium of 8 intracavitary of storage tank by chamber outside high pressure be sent to cooling equipment 9,10.
When condenser 3 is run, the solenoid valve 47 on 11 outlet pipe of storage tank is opened, and solenoid valve 37 is opened, in 11 inner cavity of storage tank
Refrigerating medium by chamber outside the water inlet of high pressure from condenser 3 be sent in condenser 3, absorb the heat of high temperature refrigerant gas
It is condensed into room temperature refrigerant liquid.The water inlet solenoid valve 42 of storage tank 12 is opened, and refrigerating medium enters after being heated in storage tank 12.When
Refrigerating medium in storage tank 11 is full of refrigerating medium after pressure sky, in storage tank 12 when, the pressure sensor 45 on 11 water outlet of storage tank is examined
The pressure reduction measured, the pressure rise that the pressure sensor 44 on 12 outlet pipe of storage tank detects, at this moment, 11 water inlet pipe of storage tank
On solenoid valve 43 open, the solenoid valve 47 on outlet pipe is closed, and the solenoid valve 37 in air inlet pipe is closed, on 12 water inlet pipe of storage tank
Solenoid valve 42 close, the solenoid valve 46 on outlet pipe is opened, and the solenoid valve 36 in air inlet pipe is opened, the load of intracavitary in storage tank 12
Cryogen by chamber outside high pressure be sent in condenser, recycle according to this.When the temperature sensor 35 on leaving condenser water pipe detects
Water temperature when being more than setting value, solenoid valve 58 is opened, and the relatively low refrigerating medium of temperature is supplemented into system, it is ensured that the condensation of refrigerant
Moderate pressure.Another program is that solenoid valve 23,13 or solenoid valve 24,14 are opened, and solenoid valve 60 is opened, and is supplemented into cooling equipment
Low temperature refrigerating medium.
Low temperature refrigerating medium can be sent in condenser 3 by opens solenoid valve 59 and be heated in storage tank 7,8, storage tank 11,12
In refrigerating medium can also be sent in evaporator 6 and cool down by opens solenoid valve 61.
Cool down equipment defrosting：Such as cooling down equipment 9 needs defrosting, and the defrosting of opening control system instructs, then solenoid valve 30,32
It closes, solenoid valve 52,54 is opened.The solenoid valve in the opening of solenoid valve 43,47,37 or storage tank 12 on the outlet pipe of storage tank 11
42nd, it 46,36 opens, the hot refrigerating medium in 11 or 12 inner cavity of storage tank is pressed in cooling equipment 9, and the heat of hot refrigerating medium is cold
But the frost layer outside wetting system absorbs, and then enters from the water inlet of condenser 3.Cooling 9 defrosting of equipment terminate, then solenoid valve 52,
54 or 51,55 close.Similarly carry out the defrosting process of next cooling equipment.
Although the present invention is shown and described by reference to preferred embodiment, ordinary skill
Personnel in the range of claims, can make form and details it is to be appreciated that the description that can be not limited to the above embodiments
On various change.
