Abstract
The invention relates to a rectifying module applicable to a water-source heat pump and a manufacturing method. In a system, a refrigerating fluid inside a loop flows sequentially in a liquid storage device, a drying filter and a thermal expansion valve through combination of four check valves, the space occupation of the structure and flowing resistance of the refrigerating fluid inside the loop are reduced by the aid of the combination method and the space connection method, a three-way joint is connected with a rectifying module and a system loop, and when a heat pump is switched between a refrigeration function and a heating function, the three-way joint is connected with the system loop and check valves to guarantee the smoothness of flowing. The rectifying module has the advantages that under the condition that functions of the heat pump are required to be switched, reverse flowing of the refrigerating fluid can be achieved successfully through the clover leaf-shaped rectifying module, simultaneously, the flowing sequence of the refrigerating fluid in the liquid storage device, the drying filter and the thermal expansion valve is not changed, and the rectifying module is generally applicable to heat pumps requiring function switching.
Description
Technical field
The present invention is specifically related to a kind of rectification module and preparation method that is applicable to water resource heat pump, belongs to the water resource heat pump refrigeration and heat-production functions and switches the technical field that rectification module is made.
Background technology
General refrigerating plant comprises these four basic building blocks of compressor, condenser, evaporimeter and expansion valve.Be used in combination situation and also need be equipped with other members such as device for drying and filtering, reservoir, cross valve, gas-liquid separator and check valve.When system only need realize can not being equipped with members such as cross valve, check valve under the situation of refrigerating function, and need to realize to freeze and during the function that heats, then need be equipped with suitable cross valve when system; And many when the refrigerant charge of system, when also needing to satisfy the function of freezing and heating, system just needs to be equipped with check valve, reservoir and device for drying and filtering.Under the normal refrigeration situation, cold-producing medium flows through reservoir, device for drying and filtering and device for drying and filtering successively in system's loop.And heat under the situation, operating mode is reverse.The existence of check valve is exactly in order to guarantee that cold-producing medium order successively of reservoir-device for drying and filtering-heating power expansion valve in system's loop flows, to guarantee the work safety of heat pump.
Summary of the invention
Purpose of the present invention provides a kind of simple in structure, economical and practical, safe and reliable exactly for overcoming above deficiency, is applicable to the rectification module that is applicable to water resource heat pump and preparation method that the water resource heat pump refrigeration and heat-production functions switches.
Technical scheme of the present invention is as follows: the described a kind of rectification module of water resource heat pump and preparation method system of being applicable to comprises check valve, elbow and threeway are formed, it is characterized in that arranging condenser and evaporimeter, left end is by the diaphragm check valve, right-hand member is connected by cross valve, connect reservoir on the diaphragm check valve, device for drying and filtering, heating power expansion valve forms the loop, heating power expansion valve connects the temperature-sensitive bag, cross valve connects gas-liquid separator, compressor reducer, oil eliminator, the shock-absorbing pipe forms the loop, at gas-liquid separator, dual pressure controller is set between the compressor reducer, technology interruption-forming system is set on the dual pressure controller.
Described check valve only allows the one-way flow of fluid, and in system, the combination by four check valves has guaranteed that the order of cold-producing medium between reservoir, device for drying and filtering and device for drying and filtering flows in the loop;
Described elbow has reduced taking up room of structure and the flow resistance of cold-producing medium in loop;
Described threeway has connected two check valves and system's loop.When heat pump refrigerating, heat-production functions switched, threeway had connected system's loop and check valve, and what guaranteed to flow is smooth and easy.
Prior art: present heat pump major part has only heating power expansion valve, does not generally select to add reservoir and device for drying and filtering as far as possible.And this structure can guarantee to contain under the situation of reservoir and device for drying and filtering still in system can the free smooth switching of carrying out refrigeration and heat-production functions, can guarantee that the safety of system also helps the Energy Efficiency Ratio of raising system.
Described a kind of rectification module that is applicable to water resource heat pump, system realizes the smooth method of freely switching of heat pump refrigerating heating function, it is characterized in that described method concrete steps are as follows:
(1) when need were realized cooling condition, the flow direction of cold-producing medium was followed successively by A-B-C-D-E-F;
(2) when need were realized heating condition, the flow direction of cold-producing medium was followed successively by F-G-C-D-H-A;
Good effect of the present invention is that the present invention is under the situation of needs switching heat pump functional, cold-producing medium by cloverleaf formula rectification module is realized reverse flow smoothly in the system that contains reservoir, device for drying and filtering and device for drying and filtering equipment, have general applicability for the heat pump that needs function to switch.
