Specific embodiment
Illustrate specific embodiment of the present utility model below.
As shown in Figure 1, one to drag six refrigeration heating control systems include expansion drum 1 and more controlled plants 10, expansion drum 1 with
Successively by the first pipeline 6, check valve 5, pump 7, evaporator 8, heating tube 9, the second pipeline 18, gas-liquid point between each controlled plant 10
Independent circulation circuit is formed from device 4 and the series connection of third pipeline 2, one end of third pipeline 2 and between check valve 5 and pump 7
The connection of first pipeline 6, the other end of third pipeline 2 are connected to gas-liquid separator 4, pass through exhaust in the outlet of gas-liquid separator 4
Pipe 15 is connect with expansion drum 1.3 refrigeration train of exhaust valve is also installed on the exhaust pipe 15 between institute's gas-liquid separator 4 and expansion drum 1
Part includes the first refrigeration pipeline 16 connecting with 8 outlet end of evaporator, and the first refrigeration pipeline 16 passes through compressor 14 and bushing type
The input end of heat exchanger 13 connects, and the outlet end of double pipe heat exchanger 13 is freezed by device for drying and filtering 12, expansion valve 11, second
Pipeline 17 is connect with the input end of evaporator 8.It is respectively provided with thermometer on above-mentioned first pipeline 6, the second pipeline 18, in the first system
Pressure gauge is respectively provided on cold pipeline 16, the second refrigeration pipeline 17.
The specific work process of the utility model is as follows:
As shown in the embodiment of fig. 1,6 controlled plants are controlled by expansion drum 1 and is in different temperature, in expansion drum 1
It is added heat-conducting medium (oil, ethylene glycol, aqueous solution, alcohol etc.), by opening check valve 5, makes heat-conducting medium in the first pipeline 6
Flowing exchanges heat by heat-conducting medium is evacuated to evaporator 8 by 7 work of pump when pump 7, and manufacturing cold source by cooling assembly makes to lead
Heat medium temperature reduce, at this time if desired controlled plant 10 when the temperature drops, cooling after heat-conducting medium directly pass through the first pipe
Road 6 flows into controlled plant 10, and heating tube 9 is in close state, and is then subjected to the outlet of control equipment 10, the second pipeline 18 flows out simultaneously
It goes successively to move in circles in the first pipeline 6 with this by third pipeline 2.If desired 10 temperature of controlled plant increases, then
Evaporator 8 is closed, heating tube 9 is opened, enters controlled plant 10 after increasing heat-conducting medium temperature, is then subjected to control equipment 10
Outlet, the second pipeline 18 are flowed out and go successively to be moved in circles in the first pipeline 6 with this by third pipeline 2.Expansion drum
1 is influenced by expanding with heat and contract with cold when heat-conducting medium is inadequate, is shunk and is filled into heat-conducting medium into the first pipeline 6, but is above-mentioned swollen
Swell 1 is not involved in above-mentioned cyclic process, therefore it is not in channeling phenomenon.When heat-conducting medium is added for the first time, due to first
Pipeline 6 has included air, by opening exhaust valve 3, isolates air by gas-liquid separator 4 and by exhaust valve 3 and exhaust pipe
15 discharges.
The utility model structure is simple, easy to use, using the utility model may be implemented an expansion drum to it is multiple by
Control equipment concurrently or separately carries out the adjusting of temperature control, and the temperature of each controlled plant is made by setting check valve and independent circulation circuit
Control is in independent control state always, avoids the occurrence of channeling phenomenon, which save working spaces, greatly reduce use cost.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape
The modification of formula.
