Description
Technical field
The hot and cold water unit that the utility model relates to is the equipment that utilizes ground water temperature heat supply or refrigeration.
Background technology
At present, be used for the energy of heat supply or refrigeration, having a kind of is to adopt source pump to extract shallow surface heat energy technology, and this source pump mainly is made up of evaporimeter, compressor, condenser, throttling arrangement.Its operation principle: the liquid refrigerant that temperature is lower rises by the cold and hot exchange back refrigerant temperature pressure with well water, enters compressor after evaporation becomes low-pressure steam, and the well water temperature descends, and is flow back in the well.Low-pressure steam becomes high pressure high temperature vapor and enters condenser by compressor compresses, descends by carrying out cold and hot exchange back temperature, pressure with heating system water, and condensation becomes liquid state.The heating system coolant-temperature gage rises, and heat is exported.The throttling step-down of condensed liquid refrigerant by throttling arrangement, liquid refrigerant temperature, pressure are descended after, get back in the evaporimeter, finish the whole process that heats.But use this unit at extremely frigid zones,, this unit is in operation is in low evaporation operating mode all the time because the temperature of well water is lower, the compressor air suction temperature is low excessively, and efficient is also extremely low, after the heat exchange of heating system water, the heating system water temperature is low, at the substandard heating temperature of cold district.
Summary of the invention
The purpose of this utility model provides a kind of hot and cold water unit, and this unit can improve the heat exchange temperature of heat supply or refrigeration by improving compressor air suction temperature and pressure, satisfies cold district temperature adjustment requirement.
The technical solution of the utility model is: a kind of cold and hot unit, comprise the evaporimeter, compressor, condenser, the throttling arrangement that are communicated with successively by pipeline, be provided with the heat exchanging water pipe in evaporimeter and the condenser, it is characterized in that: on the pipeline between evaporimeter and the compressor, be in series with superheater, be provided with the heat exchanging water pipe in this superheater housing, heat exchanging water pipe's import is communicated with cold water pipe, and heat exchanging water pipe's outlet heat exchanging water pipe import interior with being located at evaporimeter is communicated with.The described cold water pipe of present technique can be well water pipe or air-conditioning system water pipe.
The lower liquid refrigerant of temperature is housed in the evaporimeter, by with the cold and hot exchange of cold water pipe after, liquid refrigerant becomes low-pressure steam and enters superheater, the low-pressure steam that present technique is at first imported cold water pipe in superheater and the superheater carries out cold and hot exchange, cold-producing medium is evaporated fully, make the temperature of low-pressure steam improve about 3-5 ℃ on original basis, simultaneously cold water temperature descends and enters evaporimeter after about about 0.5-1 ℃, carry out cold and hot exchange with the lower liquid refrigerant of temperature again, can improve the flow velocity of cold water, make the leaving water temperature of cold water pipe lower, save the cold water consumption, save the power that water pump consumes, compressor air suction temperature and pressure are improved, thereby have improved heating capacity about about 20%.Make the COP value of whole system obtain improving.Satisfied the temperature requirement of different regions heat supply or refrigeration.
Description of drawings
Accompanying drawing is the structural representation of the utility model hot and cold water unit.
The heat exchanging water pipe of the heat exchanging water pipe of the heat exchanging water pipe of 1 condenser, 2 condensers, 3 compressors, 4 evaporimeters, 5 superheaters, 6 superheaters, 7 evaporimeters, 8 throttling arrangements, 9 well water pipes or air-conditioning system water pipe among the figure.
The specific embodiment
Cold and hot unit mainly comprises by evaporimeter 4, compressor 3, condenser 2, throttling arrangement 8, each equipment is communicated with successively by pipeline, be provided with heat exchanging water pipe 7,1 in evaporimeter 4 and the condenser 2, liquid refrigerant is housed in the evaporimeter, the characteristics of present technique are to be in series with superheater 5 on the connecting pipe between evaporimeter 4 and the compressor 3, be provided with heat exchanging water pipe 6 in this superheater housing, this heat exchanging water pipe's import is communicated with well water pipe or air-conditioning system water pipe 9, exports heat exchanging water pipe 7 imports interior with being located at evaporimeter and is communicated with.This unit connects and composes three closed circuits by pipeline, and the medium in first loop is well water or air-conditioning system water, gets back to well or air-conditioning system by the heat exchanging water pipe 6 of well water pipe or air-conditioning system water pipe 9 outputs in superheater, the heat exchanging water pipe 7 in the evaporimeter; The medium in second loop is a cold-producing medium, and liquid refrigerant evaporates in evaporimeter 4, superheater 5 and becomes steam and enter compressor 3 and get back in the evaporimeter through condenser 2, throttling arrangement 8 liquefies.Medium in the tertiary circuit is heating system water or well water, and heating system water or well water are got back in heating system or the well through the heat exchanging water pipe 1 in the condenser.Heat exchange is carried out in first loop and second loop in superheater, evaporimeter, second loop and tertiary circuit carry out heat exchange in condenser.
Under heating condition, because well water has at first entered superheater and low-pressure steam carries out cold and hot exchange, cold-producing medium is evaporated fully, make the temperature (pressure) of low-pressure steam improve (about 3-5 ℃) on original basis, well water temperature decline (about about 0.5-1 ℃), enter evaporimeter then, carry out cold and hot exchange with the lower liquid refrigerant of temperature again, can improve the flow velocity of chilled water, make the chilled water leaving water temperature of whole device lower, save the well water consumption, save the power that water pump consumes, the heating capacity that improved (about about 20%) makes whole system COP value obtain raising.Under the cooling condition, air-conditioning system water at first enters superheater and low-pressure steam carries out cold and hot exchange, cold-producing medium is evaporated cmpletely, temperature, the pressure of low-pressure steam are improved on original basis, steam temperature improves about 3-5 ℃, the air-conditioning system coolant-temperature gage descends about about 0.5-1 ℃, air-conditioning system water enters evaporimeter more then, the liquid refrigerant lower with temperature in the evaporimeter carries out cold and hot exchange, can improve the flow velocity and the flow of air-conditioning system water, improve evaporation load, obtain more refrigeration capacity, make whole system COP value obtain improving.
