Abstract
The invention provides a water path switching system replacing a four-way reversing valve. The water path switching system comprises a ground source heat exchanger, an air conditioner heat exchanger, a ground buried pipe and an air conditioner coil pipe, wherein a switching valve a is connected with a switching valve c through a switching pipe a, a ground source pipe a and an air conditioner pipe a are connected through a switching pipe b, the switching valve b is connected with a switching valve d through a switching pipe d, and a ground source pipe b is connected with an air conditioner pipe b through a switching pipe c. The water path switching system has the beneficial effects that the structure of a ground source heat pump machine unit refrigeration system is simplified, in the air conditioner mode, the system effect is realized through switching the water path system, and the debugging time is reduced, so the system is more stable; through simplifying the internal structure of a ground source heat pump machine unit, the modularization of the refrigeration system can be easily realized; through simplifying the internal structure of the ground source heat pump machine unit, the fault rate of the machine unit is reduced, the maintenance and the repair are convenient, meanwhile, the water path system is arranged outside the machine unit, and the overhaul and the maintenance are also easy; a condenser and an evaporator arranged in the system are not alternately used due to the air conditioner mode replacement, so the performance of an air conditioner is stable.
Description
Technical field
The present invention relates to air-conditioning water route switched system, especially a kind of water route switched system replacing four-way change-over valve.
Background technology
Along with the growth in the living standard of people, require also to significantly improve to the comfort level of living environment, require also more and more higher to the instructions for use of air-conditioning, performance requirement and comfort level like this.In existing air-conditioning equipment, China is still based on air-source, because it requires lower in environmental protection, installation, but in today of energy scarcity, country encourages use geothermal energy air-conditioner set to replace or partly replace existing air source air conditioning group, and in existing earth source heat pump Crew Cooling System, the parts mainly comprised are: compressor, cross valve, condenser, expansion valve, evaporimeter, within the system, freezing with heating is all controlled by cross valve.
Four-way change-over valve carries out work under the driving of coil, in refrigeration with heating mode handoff procedure, the function of plate type heat exchanger also there occurs change, during refrigeration, ground source plate changes and uses as evaporimeter as condenser, air conditioner side plate converter, when switch to heat time, ground source plate changes and uses as condenser as evaporimeter, air conditioner side plate converter, refrigeration mode is different from the heat exchange area of heating mode to evaporimeter and condenser in theory, under this structure, ground source and the plate of air-conditioning side change heat exchange area and can only select the same.
Throttle mechanism within the system generally selects heating power expansion valve, heating power expansion valve has unidirectional and two-way dividing, when employing two-way heating power expansion valve is that refrigeration mode and heating mode realize at same expansion valve, just refrigerant flow direction is contrary, in this case just compare and be difficult to take into account refrigeration and the effect heated, may under certain conditions, refrigeration is fine, but heating effect does not reach requirement, otherwise heating effect is fine, but refrigeration does not reach requirement.
Therefore, the technology being badly in need of a kind of improvement solves above-mentioned technological deficiency.
