Cold-hot integrated die heater
Technical field
The present invention relates to die heater field, it is more particularly related to a kind of cold-hot integrated die heater.
Background technology
Die heater controls equipment also known as circulating temperature, and conventional die heater typically realizes heating up by electrical heating
Purpose, realizes cooling purpose by cooled circulated medium.In practical application in industry occasion, generally there is one
Mould or other control objects need high temperature and two kinds of temperature of low temperature.Chill and heat is often had in production technology
The situation of mould associated working, general hot-die needs circulating heater to its liter of temperature control, it is achieved material produces
The fusing or hot-forming of product;Chill needs cooling back installation to control its cooling, it is achieved produce material
Product quickly cool down, in order to the demoulding enter lower one production process, also have by cooling realize chemistry or
Physical action thus realize other purpose.
For similar use above occasion, the most existing way is by cold-hot integrated type die heater
Control, also have and realized by a single cooler and another heater.Cooler is the most logical
Crossing vapor-compression chiller to realize, heater is typically realized by electrical heating unit.Owing to steaming
A kind of Energy Transfer Equipment of vapour pressure compression type refrigerating unit, it passes through the heat in material or mould
Heat exchange with evaporimeter is transferred in refrigerant, eventually through condenser discharge to external environment, and adds
Thermal uses by converting electrical energy into heat energy, and actually in discharges heat, another side exists
Produce heat, there is the waste of energy.As described above, if can be by the heat of refrigerating plant discharge
It is recycled and recycles, can cancel or be greatly reduced the power of heater, in whole service
Journey realizes significantly energy-saving benefit.
Summary of the invention
For weak point present in above-mentioned technology, the present invention provides a kind of pump type heat cold-hot integrated mould temperature
Machine, uses the circulation of cascade type steam compressing hot pump to combine energy storage liquor box, is obtained by condenser discharge heat
Recycle, higher hot side can be realized by the circulation of cascade type steam compressing hot pump and use temperature and relatively
Low cold and hot use temperature, cancels electric heater unit, relative existing product, has significant power savings advantages,
And improve the security of unit.
In order to realize according to object of the present invention and further advantage, the present invention is by the following technical programs
Realize:
A kind of cold-hot integrated die heater, includes framework, it is characterised in that: it is provided with pipe on framework
Road connect condenser, the first compressor, first throttle device, evaporative condenser, the second compressor,

The outlet of one throttling arrangement, the evaporation side outlet of evaporative condenser is by pipeline and the first compressor
Inlet communication, the condensation side import of evaporative condenser is passed through pipeline and the outlet of the second compressor, is steamed
Feel cold the condensation side outlet of condenser by the inlet communication of pipeline Yu three-way diverter valve, going out of the first evaporimeter
Mouth passes through pipeline and second section by pipeline and the inlet communication of the second compressor, the import of the first evaporimeter
The outlet of stream device, the import of the second throttling arrangement and three-way diverter valve outlet, the
The outlet of two evaporimeters is by pipeline and the inlet communication of the second compressor, and the import of the second evaporimeter is passed through
Pipeline and the outlet of the 3rd throttling arrangement, another of the import of the 3rd throttling arrangement and three-way diverter valve
Individual outlet;Hot side liquid return hole connects with the inlet of hot side liquor box, the liquid outlet of hot side liquor box
With the inlet communication of hot side circulating pump, hot side circulation delivery side of pump connects with hot side supply opening;Liquid is returned in cold side
Mouth connects with the inlet of cold side liquor box, and the liquid outlet of cold side liquor box connects with the import of cold side circulating pump
Logical, cold side circulation delivery side of pump connects with cold side supply opening.
Described condenser is liquid-cooling type condenser, and the first evaporimeter is coolant build evaporimeter, the
Two evaporimeters are coolant build evaporimeter or cooling air type evaporimeter.
Described condenser immerses hot side liquor box, carries out heat exchange with hot side solution;First evaporimeter leaching
Enter cold side liquor box, carry out heat exchange with cold side solution.
The present invention switching by three-way diverter valve, can realize multiple-working mode.Realized by condenser
Recuperation of heat works, and realizes cold-storage by the first evaporimeter and works, and cold side liquor box to uniform temperature value is changeable
To the second evaporator operation.
When unit is started working, first running hot side circulating pump and cold side circulating pump, three-way diverter valve leads to
Cross manually or electrically changing flow direction, the condensation side outlet of connection evaporative condenser and entering of the second throttling arrangement
Mouthful.
After set steady work, the first compressor and the second compressor both participate in energising and run, the second compression
Machine absorbs the cold-producing medium low-pressure steam in low pressure line in running, is compressed into high temperature and high pressure gas and enters
Entering the condensation side in evaporative condenser, then high-temperature high-pressure refrigerant gas is cooled in evaporative condenser
Medium condensation heat release, becomes and has the liquid of certain degree of supercooling, by the second throttling arrangement or the 3rd throttling
The reducing pressure by regulating flow effect of device becomes the gas-liquid mixture of low-temp low-pressure;The gas-liquid mixture of low-temp low-pressure enters
Enter in the first evaporimeter or the second evaporimeter and be vaporized heat absorption, under being again introduced in the second compressor entering
Circulation once;First compressor absorbs the cold-producing medium low-pressure steam in low pressure line in running,
Being compressed into high temperature and high pressure gas and enter condenser, then high-temperature high-pressure refrigerant gas is the coldest
But medium condensation heat release, becomes and has the liquid of certain degree of supercooling, by the throttling fall of first throttle device
Pressure effect becomes the gas-liquid mixture of low-temp low-pressure;The gas-liquid mixture of low-temp low-pressure enters evaporative condenser
In evaporation side be vaporized heat absorption, then entered the circulation entered in the first compressor next time by pipeline.
Condenser immerses hot side liquor box and realizes heat release, and the first evaporimeter immerses cold side liquor box and realizes heat absorption,
Set required value when cold side liquor box temperature arrives, switch to the second evaporator operation by three-way diverter valve,
Thus maintain the temperature stabilization of cold side liquor box.
