Abstract
The utility model relates to an afterheat energy-saving air source heat pump air conditioning in a metering room in an oil field, which comprises an air source heat pump air conditioner formed by orderly connecting a refrigeration compressor, a four-way change valve, an indoor heat exchanger, an expansion valve, an outdoor heat exchanger and a gas-liquid separator through refrigerant tubes. A bypass refrigerant valve is connected in series in the refrigerant tube which is used for connecting the four-way change valve and the gas-liquid separator. A coupling heat exchanger formed by a refrigerant crooked tube and a fluid tube is connected with the bypass refrigerant valve in parallel. Cut-off valves of the coupling heat exchanger are respectively arranged at the refrigerant inlet end and outlet end of the coupling heat exchanger. By additionally arranging the coupling heat exchanger in a circulation loop of the air source heat pump air conditioner, the coupling heat exchanger is used for obtaining the afterheat of fluid media in the metering room, so the heating efficiency of the air source heat pump air conditioner is improved, and the energy consumption for heating is largely reduced when the heating requirement for a metering room in an oil field at cold area is satisfied.
Description
Technical field
The utility model relates to air source heat pump air-conditioner, is specifically related to afterheat energy-saving type air source heat pump air-conditioner between a kind of petroleum metering.
Background technology
The field produces facility is equipped with numerous metering rooms.Since between petroleum metering mostly away from the central heating heat supply network, so winter heating difficulty relatively.The air source heat pump air-conditioner product heating of using prior art is a kind of solution, and still, because outside air temperature is very low, the heating effect of existing air source heat pump air-conditioner device is relatively poor relatively, and energy consumption is very high at cold district.And the generation in the process of equipment operation of the hot fluid pipeline between petroleum metering has a large amount of waste heats, how to utilize these waste heats, is to produce and service for life, and realization is energy-saving and cost-reducing, is to need one of major issue that solves in the oilfield process.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and afterheat energy-saving type air source heat pump air-conditioner between a kind of petroleum metering is provided.
The technical scheme that realizes above-mentioned purpose is: afterheat energy-saving type air source heat pump air-conditioner between a kind of petroleum metering, it includes by the refrigerant line refrigeration compressor that is linked in sequence, four-way change-over valve, indoor heat exchanger, expansion valve, the air source heat pump air-conditioner device that outdoor heat exchanger and vapour liquid separator are formed, in the refrigerant line of four-way change-over valve and vapour liquid separator, be connected in series with the bypass refrigerant valve, be connected in parallel to a coupled heat exchanger of forming by cold-producing medium crooked pipe and fluid line with described bypass refrigerant valve, be respectively arranged with the coupled heat exchanger Shuttoff Valve at the refrigerant inlet end and the port of export of this coupled heat exchanger.
Above-mentioned bypass refrigerant valve and coupled heat exchanger Shuttoff Valve can be electrically operated valve or electromagnetic valve.
The utility model is by installing a coupled heat exchanger additional in the closed circuit of air source heat pump air-conditioner device, utilize this coupled heat exchanger to obtain the waste heat of metering room fluid media (medium), improve the heating efficiency of air source heat pump air-conditioner device, satisfying between the cold district petroleum metering in the heat supply heating requirement, heating energy consumption is reduced greatly.
Description of drawings
Accompanying drawing is an afterheat energy-saving type air source heat pump air-conditioner structural representation between this petroleum metering.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing, afterheat energy-saving type air source heat pump air-conditioner includes by the refrigerant line refrigeration compressor 1 that is linked in sequence between this petroleum metering, four-way change-over valve 2, indoor heat exchanger 3, expansion valve 4, the air source heat pump air-conditioner device that outdoor heat exchanger 5 and vapour liquid separator 6 are formed, in the refrigerant line that connects four-way change-over valve 2 and vapour liquid separator 6, be connected in series with bypass refrigerant valve 7, be connected in parallel to a coupled heat exchanger 10 of forming by cold-producing medium crooked pipe 8 and fluid line 9 with the bypass refrigerant valve, be respectively arranged with coupled heat exchanger Shuttoff Valve 11 and 12 at the refrigerant inlet end and the port of export of coupled heat exchanger 10.
When the utility model is specifically implemented, cold-producing medium crooked pipe 8 can be wrapped in the outside of fluid line 9 shown in accompanying drawing embodiment, constitute the coupled heat exchanger of external cold-producing medium crooked pipe, also can be assemblied in the fluid line 9, constitute the coupled heat exchanger of built-in cold-producing medium crooked pipe.Bypass refrigerant valve 7 and coupled heat exchanger Shuttoff Valve 11,12 can adopt manually-operated gate, electrically operated valve or electromagnetic valve.In outdoor heat exchanger 5 can be installed in outdoor or is installed between the metering room fluid line.
During the utility model winter heating, by the refrigerant gas after the outdoor heat exchanger 5 evaporation heat absorption after four-way change-over valve 2 and valve 11 are overheated to crooked pipe 8, enter refrigeration compressor 1 by valve 12 and vapour liquid separator 6, improve the suction temperature of compressor, reach the purpose that improves air source heat pump air-conditioner heating operation efficient, cuts down the consumption of energy.
By refrigerant gas indoor heat exchanger 3 evaporation absorption chambers in heat after through four-way change-over valve 2, valve 7 and vapour liquid separator 6 enter refrigeration compressor 1 when freezing summer, does conventional refrigeration air-conditioner operation.
The utility model is particularly suitable for using between petroleum metering.The utility model is applicable to other occasion use that possesses the hot fluid pipeline too.
