Description
Technical field
The utility model relates to the heating and cooling field, especially relates to a kind of airtight refrigeration heating circulation system.
Background technology
Airtight refrigeration heating circulation system can provide the EGR of low-temperature receiver and thermal source, and working range is wider, is used for the behaviors such as pharmacy, chemical industry, biology, for reactor, groove etc. provides thermal source and low-temperature receiver, also can be used for the heating and cooling of other equipment.Present airtight refrigeration heating circulation system can not make refrigerating medium directly drop to low temperature from a high position, as adds gentle cooling high load capacity work simultaneously, makes it the lost of life, and cost is larger.
Summary of the invention
The utility model purpose is to provide a kind of airtight refrigeration heating circulation system that can fast cooling when high temperature.
For achieving the above object, the utility model can be taked following technical proposals:
Airtight refrigeration heating circulation system described in the utility model comprises refrigerating medium passage and coolant channel, is communicated with to be provided with circulating pump and gas-liquid separator on described refrigerating medium passage, and the inlet of described gas-liquid separator is connected with expansion vessel; Be provided with compressor on described coolant channel; Described refrigerating medium passage and coolant channel the first side runner by pipeline and plate type heat exchanger and the second side runner respectively consist of the loop, are communicated with to be provided with air-cooled condenser, reservoir, device for drying and filtering, magnetic valve and heating power expansion valve between the second side runner of described compressor and plate type heat exchanger; Described circulating pump and gas-liquid separator are parallel with heat tunnel, precooling passage and refrigerating channel by pipeline, be in series with electric heater and add thermoelectrical magnetic valve on described heat tunnel, be in series with air-cooled forecooler and precooling magnetic valve on described precooling passage, be in series with the first side runner and the refrigeration magnetic valve of plate type heat exchanger on described refrigerating channel; Be respectively arranged with check-valves on the fluid pipeline of heat tunnel, precooling passage and refrigerating channel.
Be provided with liquid level gauge on described expansion vessel.
The utility model advantage is can be different according to design temperature, open respectively refrigeration, heating, precooling pipeline and carry out work, realize that different temperature controls, and can use a kind of refrigerating medium directly to drop to low temperature from high temperature.
