Abstract
The utility model relates to a high efficiency water source heat pump air conditioner which can make use of water from river, lake and sea. The utility model comprises a water source heat pump formed by a compressor, an evaporator, a condenser and an expansion valve. A water source connecting system which consists of a filter, a connecting water pipe and a pump is arranged to match the evaporator. An air conditioner terminal system which consists of a circulation pump and air conditioner terminal equipment is arranged to match the condenser. The compressor is a low back-pressure low temperature compressor, and the evaporator is a single water path straight-through full liquid evaporator, and the expansion valve is an electronic expansion valve. The utility model adopts the low temperature compressor so as to adapt to the low water temperature characteristic of river, lake and sea in winter, thus enhancing heating efficiency when the heat pump adopts the low temperature water. The evaporator is designed to be the single water path straight-through full liquid structure which can effectively avoid freezing of evaporator and can guarantee safe and reliable running of the water source heat pump. The adoption of the electronic expansion valve can adapt to a big temperature difference characteristic of river, lake and sea water between winter and summer, thus guaranteeing high efficiency running of the water source heat pump in both winter and summer.
Description
Technical field
The utility model relates to water source heat pump air-conditioner, is specifically related to a kind of high-effect river, river, lake, sea water source heat pump air-conditioning.
Background technology
At present, the main water resource heat pump of forming by compressor, evaporimeter, condenser and expansion valve, because compressor adopts high temperature compressed machine in the middle and high back pressure type, and evaporimeter adopts many water formula structure, institute's treatable water source temperature is more than 3 ℃, and when the water source temperature was relatively low, the heating efficiency of its heat pump was low, and easily in evaporimeter, form and freeze, cause water resource heat pump can't extract river, river, lake, seawater in the winter time and move safely and reliably.
Summary of the invention
The purpose of this utility model be at river, river, lake, seawater water temperature winter, summer the temperature difference big, the characteristics that water temperature is low provide a kind of high-effect river, river, lake, sea water source heat pump air-conditioning.
The technical scheme that realizes above-mentioned purpose is: a kind of high-effect river, river, lake, sea water source heat pump air-conditioning, it includes the water resource heat pump of being made up of compressor, evaporimeter, condenser and expansion valve, matching with the evaporimeter of water resource heat pump is equipped with by filter, is connected the water source connected system that water pipe and water pump are formed, and matching with the condenser of water resource heat pump is equipped with the air conditioning terminal system that is made up of water circulating pump and air conditioner end equipment; Its described compressor is low back pressure type cryogenic compressor; Described evaporimeter is the full liquid type evaporimeter of single water journey through type; Described expansion valve is an electronic expansion valve.
The full liquid type evaporimeter of single water journey through type of the present utility model has horizontal cylindrical shell, cylindrical shell two ends configuration tube sheet, horizontal between two tube sheets have an evaporation-cooled tube, the outside at each tube sheet disposes water cover respectively, on water cover, be respectively arranged with water inlet and delivery port, form the straight-through water flow structure of single current journey, in cylindrical shell bottom configuration refrigerant inlet, in the outlet of cylindrical shell top configuration refrigerant gas.The corresponding water fender that disposes in the water inlet water cover with water inlet.
The utility model adopts low back pressure type cryogenic compressor, the heating efficiency when using water at low temperature in order to adapt to river, river, lake, characteristic that extra large water temperature in winter is low, to improve heat pump.And evaporimeter is set to the full liquid type structure of single water journey through type, by shortening the time of staying of water at low temperature in evaporimeter, effectively avoids evaporimeter to freeze, and guarantees that water resource heat pump moves safely and reliably.Adopt electronic expansion valve, then can adapt to river, river, lake, seawater winter, water temperature difference variation in summer characteristics greatly, guarantee that water resource heat pump all can efficiently move with summer in the winter time.

Fig. 2 is the evaporation structure schematic diagram of this water source heat pump air-conditioner.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing 1, the utility model includes the water resource heat pump of being made up of compressor 1, evaporimeter 2, condenser 3 and expansion valve 4, matching with the evaporimeter of water resource heat pump is equipped with by filter 5, is connected the water source connected system that water pipe 6 and water pump 7 are formed, and matching with the condenser 3 of water resource heat pump is equipped with the air conditioning terminal system that is made up of water circulating pump 8 and air conditioner end equipment 9.Its described compressor 1 is low back pressure type cryogenic compressor; Evaporimeter 2 is the full liquid type evaporimeter of single water journey through type; Expansion valve 4 is an electronic expansion valve.
In conjunction with the accompanying drawings operation principle of the present utility model is described as follows:
As accompanying drawing 1, the high-temperature gas cold-producing medium that compressor 1 is discharged carries out heating operation by the heating system of being made up of water circulating pump 8 and air conditioner end equipment 9 to indoor heat release in once holding of condenser 3 discharges condenser heat in heating water to secondary terminals.Condensed refrigerant liquid absorbs heat in the river, river, lake, seawater of once end input to the evaporation of the secondary terminals of evaporimeter 2 after expansion valve 4 throttlings, gaseous refrigerant is sucked the back by compressor 1 to be continued compression and repeat above-mentioned circulation.River, river, lake, seawater are back to and finish the water source circulation in river, river, lake, the seawater by connecting water pipe 6 through the once end of evaporimeter 2 again through filter 5 to water pump 7.
As accompanying drawing 2, river, river, lake, seawater enter evaporimeter 2 through water inlet 13, are discharged by delivery port 14 by straight-through cooling tube 12 backs.Refrigerant liquid from expansion valve enters evaporimeter by refrigerant inlet 15, and evaporation absorbs and to become gas in the water in the cooling tube 12 of flowing through behind the heat and discharge and be back to compressor through exporting 16.The setting of its water fender 17 can improve the uniformity of current by each cooling tube 12.
Compressor 1 of the present utility model adopts frequency conversion or increases Unloading Control.Evaporimeter 2 adopts the material manufacturing of sea water resistance.
The utility model installs four-way change-over valve or eight conversion valves additional in water source heat pump system, can realize the conversion of heating and refrigerating operaton.
