Abstract
The utility model relates to an air-source heat pump hot water unit with a refrigerating output recovery function. A compressor, a cold-dispersing coil and a water heater are arranged in a refrigerant circulation pipeline of the unit. The unit is characterized in that: an evaporator, which can be of a shell-tube type, a plate type or a double-pipe type, is arranged in the refrigerant circulation pipeline as well, and is arranged after the water heater in the refrigerant flow direction of the refrigerant circulation pipeline, moreover, an evaporator pipeline with the evaporator is connected in parallel with a cold-dispersing coil pipeline with the cold-dispersing coil, the evaporator pipeline and the cold-dispersing coil pipeline are converged and then connected into the inlet of the compressor, and electromagnetic valves are respectively arranged in the evaporator pipeline and the cold-dispersing coil pipeline.
Description
Technical field
The utility model relates to the refrigeration plant of central air-conditioning, relates in particular to the air-conditioning unit of the cold recovery function of air-source heat pump hot water band.
Background technology
The air-source heat pump hot water group of existing air-conditioning unit only has the function that hot water is provided.The shortcoming of this unit is: function ratio is more single, and the domestic hot-water can only be provided, and the utilization rate of unit is not high enough, in the limited unit placement space of user, can not realize client's multi-functional requirement.Under the increasing situation of the heat-pump hot-water market demand, the client will certainly be also more and more for the requirement of heat pump water-heating machine function.
The utility model content
The purpose of this utility model is to provide the group of the air-source heat pump hot water with cold recovery function, to increase the function of heat pump water-heating machine, can provide function corresponding when the client needs cold water.
Air-source heat pump hot water group with cold recovery function of the present utility model, in its medium circulation pipeline compressor is set, cold elimination coil pipe and water heater, be characterized in, also be provided with evaporimeter in the medium circulation pipeline, the pattern of evaporimeter can be shell-tube type, board-like or bushing type, on the refrigerant flow direction of medium circulation pipeline, evaporimeter is arranged on after the water heater, and, the cold elimination coil pipe pipeline at the evaporator pipeline at evaporimeter place and cold elimination coil pipe place is connected in parallel, the inlet of compressor, evaporator pipeline are inserted in evaporator pipeline and back, cold elimination coil pipe pipeline interflow, magnetic valve is set respectively in the cold elimination coil pipe pipeline.
When the client did not need cold recovery, the control by magnetic valve switched to the cold elimination coil pipe pipeline, by cold elimination coil pipe cold is passed to air.System pipeline switches to the connection evaporimeter by the control of magnetic valve when the client needs cold recovery, by evaporimeter cold is passed to recirculated water, thereby reach the purpose that cold water is provided, therefore the utility model overcomes the defective that the last air-source heat pump hot water group of prior art can not chilled water, the unit of the cold recovery function of a kind of novel air source heat pump hot water unit band is provided, it provides cold water when guaranteeing user domestic hot-water amount, reduced scattering and disappearing of effective cold, increase the function of the chilled water of unit, and improved the utilization ratio of unit.
Description of drawings
Fig. 1 is the system flow simplified diagram with air-source heat pump hot water group of cold recovery function of the present utility model.
The specific embodiment
The air-conditioning unit comprises compressor 1, water heater 2, cold elimination coil pipe 3, evaporimeter 4, heating power expansion valve 5, evaporator tube way solenoid valve 11, cold elimination coil pipe pipeline electromagnetic valve 12 and some system pipeline accessories etc. as shown in Figure 1.Comparing has air source heat driven heat pump hot water unit now, has increased by one road evaporator pipeline 100 after water heater 2 again, and this evaporator pipeline 100 is connected in parallel with the cold elimination coil pipe pipeline, collaborates the inlet of back access compressor 1 at last with the cold elimination coil pipe loop.
Be provided with evaporator tube way solenoid valve 11 in the evaporator pipeline 100.Cold elimination coil pipe pipeline electromagnetic valve 12 is set in the cold elimination coil pipe pipeline.
Freeze by means of 4 pairs of water of evaporimeter, heat by means of 2 pairs of water of water heater.
When the client did not need cold recovery, system pipeline switched to the cold elimination coil pipe pipeline by the control of magnetic valve 11,12, by cold elimination coil pipe cold is passed to air.System pipeline switches to connection evaporimeter 2 by the control of magnetic valve 11,12 when the client needs cold recovery, by evaporimeter cold amount is passed to recirculated water, thereby reaches the purpose that cold water is provided.
Air-source heat pump hot water group with cold recovery function not only can provide living-hygienic hot water to the user individually, can also provide the client needed cold yield when the user provides the domestic hot-water.Unit can also be according to client's setting, switches being with cold recovery and not being with between the cold recovery function.
Claims (2)
1. the air-source heat pump hot water group that has cold recovery function, compressor, cold elimination coil pipe and water heater are set in its medium circulation pipeline, be characterized in, also be provided with evaporimeter in the medium circulation pipeline, on the refrigerant flow direction of medium circulation pipeline, evaporimeter is arranged on after the water heater, and, the cold elimination coil pipe pipeline at the evaporator pipeline at evaporimeter place and cold elimination coil pipe place is connected in parallel, the inlet of compressor is inserted in evaporator pipeline and back, cold elimination coil pipe pipeline interflow, in evaporator pipeline, the cold elimination coil pipe pipeline magnetic valve is set respectively.
