In order to more clearly describe the present invention, the work process of the present invention described below such as following table:
Different operation modes electric check valve door state table in experimentation
Sequence number | Pattern | Heat pump | Electric check valve state |
1 | Add heat fusing pattern | Open | SV1 closes, and SV2 closes, and SV3 opens, and SV4 opens, and SV5 opens |
2 | Cooled and solidified pattern | Open | SV1 opens, and SV2 opens, and SV3 closes, and SV4 closes, and SV5 opens |
3 | Out of service | Stop | SV1 closes, and SV2 closes, and SV3 closes, and SV4 closes, and SV5 closes |
First, heat pump starts, and high-temperature gas cold-producing medium is discharged from compressor outlet, enters water cooling cold
Heat is passed to the water in hot water water storage box by condenser, is condensed into liquid, and liquid refrigerant saves through expansion valve
Becoming gas-liquid two-phase cold-producing medium after stream, two phase refrigerant enters vaporizer and absorbs the heat of cold water, becomes gas
Body finally enters compressor and completes a kind of refrigeration cycle.
Then, treat that the water temperature of cold water water storage box and hot water water storage box is reached value set in advance by heat pump
Time, start water circulating pump, carry hot and cold water to sample test district.
Heat fusing and the working method under cooled and solidified both of which of adding set forth below:
1, heat fusing pattern is added: water circulating pump extracts hot water from heating water tank, is transported to sample area,
Hot water returns boiler afterwards, and water circulation route is as shown in red solid line arrow in Fig. 1;Treat that sample is complete
Running down, its temperature rises to default value Thigh and (typically takes higher than this sample phase transition temperature 10
The temperature value of degree), automatic control system regulation electric check valve, operating mode is switched to refrigerating mode;
2, cooled and solidified pattern: water circulating pump (5) extracts cold water from cold water storage cistern, is transported to sample
Product district, afterwards cold water Returning water case, water circulation route is as shown in dotted arrow blue in Fig. 1;Treat
Sample solidifies completely, and its temperature is reduced to default value Tlow and (typically takes less than this sample phase alternating temperature
Spend the temperature value of 10 degree), automatic control system regulation electric check valve, operating mode is switched to heating mode.
After electromagnetic valve switches 2 times, enumerator is designated as 1 circulation;Heating/cooling operating mode is followed repeatedly
Ring, when the counted cycle-index of device to be counted reaches the cycle-index set by system, program can make prompting
And the operation of termination device, stop heat pump and water circulating pump and closedown electric check valve valve successively.
The harvester such as temperature, flow and counting assembly are persistently carried out, and treat that manual operation is stopped.
The preferred embodiment of the present invention described in detail above, it will be appreciated that the common skill of this area
Art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all
Technical staff passes through logical analysis, reasoning according to present inventive concept on the basis of prior art in the art
Or according to the limited available technical scheme of experiment, all should determined by the claims
Protection domain among.
