Description
Technical field
The utility model relates to the water source heat pump units technical field, particularly a kind of water source heat pump units that is applicable to cold and heat combined supply.
Background technology
Water resource heat pump is to have utilized earth surface or shallow-layer water source; Like the solar energy that absorbs in underground water, river and the lake and geothermal energy and the low-grade heat source that forms; Adopt heat pump principle,, carry out the heating air-conditioner system of power conversion through a spot of high-order electric energy input.Because its energy-conserving and environment-protective characteristic is classified as the regenerative resource category by country.
Because environmental protection, requirements of saving energy, the burning coal boiler room of domestic hot-water supply is transformed one after another, but no matter fuel oil still burns natural gas, and the cost of hot water is all very high.Therefore research can supply cold (heat) water of idle call and domestic hot-water's source pump to have good economy and environmental benefit simultaneously.
China's utility model patent 03266196.7 disclosed a kind of cold and heat combined supply heat pump hot water unit provides a kind of source pump that can realize above-mentioned functions, shown in accompanying drawing 1.The concrete operation principle of this utility model is: the liquid refrigerant that is in the low-pressure low-temperature state is sent into evaporimeter 21 through pipeline; The indoor air evaporimeter of flowing through under the driving of blower fan 18; Be evaporated to gas behind the heat of the working medium absorption room air in the evaporimeter; Through compressor 2 actions, become high-temperature high-pressure state, deliver to condenser 14; The recirculated water of water circulating pump 17, is guided to hot water in the water storage box 16 through pipeline heat transferred water through condenser 14 again.Pass through the liquid state that flow controller 15 becomes low-temp low-pressure again from the working medium that condenser 14 comes out, carry out returning in the compressor after the heat exchange with air; Through the air of evaporimeter 21 cooling, send into the cooling of room conditioning room summer, winter or need not lower the temperature the time, discharge outdoor through reversal valve 19.At this moment need window in the room, makes room air and atmosphere through evaporimeter 21.It is thus clear that this device can not solve cold and hot imbalance problem in summer, this possibly cause the hot water temperature higher, can not play good cooling effect to condenser, has a strong impact on the coefficient of performance of refrigerating of system.
In addition, Chinese utility model patent 200620086384.4 disclosed a kind of complete recuperation of heat cold water source pump also can realize the function that above-mentioned cold and heat combined supply heat pump unit is provided, shown in accompanying drawing 2.The operation principle of this device is: it is divided into the identical two parts of structure with the water system in the condenser 14; Left side cavity is connected with the air conditioner water circulation line as condenser use normally, and right cavity is connected as the health hot water heat exchanger with the health hot water circulation line and uses.Refrigeration, when heating, the left cavity work of evaporimeter 21 and condenser 14 is supplied with user terminals through air conditioner water circulation line 22.When producing health hot water, the right cavity work of condenser 14 for the user provides hot water, can hot water storage tank in replenish running water during use through health hot water circulation line 23-hot water storage tank 9, hot water storage tank 9-delivery port 24.In the course of work, only need the health hot water circulating pump work on the pipeline, and the circulating pump on the air conditioner water circulation line 7 need not be worked.This patent is divided into two kinds of independently operating modes with hot water production and cold and heat supply, can not well realize supplying air conditioner water and hot water production function real the time, has seriously limited it and has used popularization.
