As a further improvement on the present invention, the temperature controlling range of glycol water is subzero four in the liquid reserve tank
Degree Celsius to subzero six degrees Celsius.
The effective effect brought due to the utilization of above-mentioned technical proposal, the present invention：The technical program is by applying ethylene glycol
The aqueous solution simultaneously enters trip temperature transmission with the use of heat exchanger, and with avoiding, heat exchanger internal-external temperature difference is excessive to cause frost, drop
The live load of low compressor, the advantageous effects of the service life of extension device；The technical program by using holding vessel,
Heat exchanger tube, first pump housing, second pump housing, circulation pipe and evaporator, circulating cooling is carried out by evaporator to glycol water,
The glycol water in liquid reserve tank is subjected to temperature exchange by heat exchanger tube and conventional refrigerants on heat exchangers again, not only had
There are the leakage of reduction end or the risk fired, improve the advantageous effects of device security, also with stopping in short-term running into
With certain cold-storage ability when electric, cushioning effect is played, prevents cold in-cabinet temperature from raising too fast advantageous effects；This skill
Glycol-cooled system is used split arrangement form by art scheme with traditional cooling down system, with avoiding refrigerator by heat
It is directly emitted to use region, reduction equipment noise is to the advantageous effects that are had undesirable effect using region.

Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further detail to the present invention.
As shown in figure 1, a kind of refrigerator of application ethylene glycol refrigerating, including compressor 1, blast pipe 2, condenser 3, condensate pans
Pipe 4, condenser fan 5, device for drying and filtering 6, expansion valve 7, heat exchanger 8, refrigerant outlet 9, refrigerant inlet 10, air inlet pipe 11,
Liquid reserve tank 12, glycol water 13, heat exchanger tube 14, first pump housing 15, second pump housing 16, circulation pipe 17, evaporator 18, evaporation
Tubule 19, evaporating fan 20 and return duct 21, the both sides of heat exchanger 8 are provided with refrigerant outlet 9 and refrigerant inlet 10；
The port of export of the compressor 1 is connected with condenser 3, device for drying and filtering 6 and expansion valve 7 in turn after blast pipe 2；The expansion
Valve 7 is connected with the refrigerant inlet 10 of the heat exchanger 8；Condenser coil 4 and condenser fan 5 are provided with the condenser 3；
The refrigerant outlet 9 of the heat exchanger 8 is communicated to the inlet end of the compressor 1 by air inlet pipe 11；In the liquid reserve tank 12
Equipped with glycol water 13；The bottom of liquid reserve tank 12 is connected after first pump housing 15 with the upper end of heat exchanger 8；Institute
The upper end for stating heat exchanger 8 is connected to the upper end of the liquid reserve tank 12 by heat exchanger tube 14；Second pump housing 16 passes through circulation pipe
17 form circulation loop using return duct 21 after evaporator 18 with the liquid reserve tank 12；Steaming is provided with the evaporator 18
Send out tubule 19 and evaporating fan 20；The allotment concentration of the glycol water 13 is 30 percent；The liquid reserve tank 12 is
Stainless steel material is made；The temperature controlling range of glycol water 13 in the liquid reserve tank 12 is subzero four degrees Celsius to zero
Lower six degrees Celsius.
For the refrigerator using inflammable, explosive working medium such as R290, R600a, the equipment completely avoid end risk of leakage
And risk is fired, ensure the life and property safety of people；Noise of the refrigerator in sales field is greatly lowered；Avoid refrigerator
The heat extraction into sales field, substantially improves sales field environment, reduces the energy consumption of whole sales field air-conditioning；And it is environmentally safe.
Relative to remote mounted refrigeration mode can solve low-temperature receiver to end pipeline it is lack of standardization it is bad walk the trouble brought, for example
Can not it is smooth vertical and horizontal, can not oil return bend etc.；Other feed pipe and liquid back pipe can use the lower-cost pipe chariots such as galvanized pipe, and
And pipeline is longer relative to what refrigerant-cycle systems can allow to walk, 20 ~ 80m really needs long pipe road to increase pump and water tank i.e.
Can；Evaporate and glycol water is full of in tubule, improve solution heat-exchange temperature in pipe, heat transfer temperature difference is reduced, so as to reduce unlimited
Place the drying loss of food；Because glycol water gradient of temperature amplitude fluctuation is small, the operation amplitude that cabinet temperature heats up therewith
Also can be smaller, thus cabinet temperature directly evaporates stabilization compared with refrigerant；There is certain cold-storage ability, peak is can adjust there is time-of-use tariffs region
Paddy period start duration has reduced operating cost, for example：Once, Feng Jia areas can recover water tank temperature to low flush tank temperature that Gu Jia areas are adjustable
Degree setting.
It the above is only the concrete application example of the present invention, protection scope of the present invention be not limited in any way；It is all to use
Technical scheme formed by equivalent transformation or equivalent replacement, all falls within rights protection scope of the present invention.
