Description
Technical field
The utility model belongs to the water dispenser technical field of supplying the hot water or cold water.
Background technology
Because environmental problems such as atmospheric ozone damage layer, global air temperature warming, unusual weather conditions are serious day by day, energy-conservation and environmental protection has become the common problem of paying close attention to of the whole mankind.
Along with the raising of people's living standard, water dispenser is popularized in people's live and work, and China's water dispenser annual production has at present reached 3,000 ten thousand, and people are more and more higher to the water dispenser performance demands, not only can provide hot water, also will provide cold water.The water dispenser heating power is generally 300-1000w, and refrigeration work consumption is generally 80-100w.One day power consumption on water dispenser of one family is the 0.5-1.5 degree, one day power consumption on water dispenser of a medium-sized office block can reach 500-1000w, China's water dispenser annual production reaches 3,000 ten thousand, this shows that the energy-saving potential on water dispenser is considerable.
Water dispenser in the market mainly contains for hot-water type (single warm type) and two kinds of patterns of heat supply water cold water type (two warm type).What adopt for the hot-water type water dispenser is electrical heating, it have simple in structure, to add heat big, heat advantage rapidly, but its power consumption is bigger, and the accident that is short-circuited easily.Cooling water hot-water type can provide hot water can provide cold water again, and its heat form also is electrical heating, but its refrigeration form has two kinds, and a kind of is semiconductor refrigerating, and another kind is a compression-type refrigeration.The refrigerating capacity of semiconductor refrigerating is smaller, and the cold-producing medium that common compression-type refrigeration adopts is a freon, can only provide to be lower than 30-40 ℃ hot water, can not satisfy the demands, need electrical heating to come supplementary heating, make the drinking machine apparatus complexity, and cold-producing medium freon there is certain destruction to environment.
The utility model content
The purpose of this utility model is exactly to overcome above-mentioned many disadvantages, with carbon dioxide heat-pump and water dispenser in conjunction with forming a system, form a CO 2 trans-critical heat pump water dispenser, supply hot and cold water simultaneously, performance carbon dioxide heat-pump system environmental protection and energy-conservation aspect advantage, a kind of energy saving and environment friendly carbon dioxide heat-pump double-temperature drinking machine promptly is provided.
For reaching above-mentioned purpose, the concrete technical scheme that the utility model is taked is as follows:
The carbon dioxide heat-pump double-temperature drinking machine, comprise circulation of heat supply water and the circulation of cooling water, it is characterized in that: circulation of cooling water and the circulation of heat supply water comprise compressor, triple valve A, hot courage or gas cooler, triple valve B (5), expansion valve, triple valve C, cold courage or evaporimeter, triple valve D, and form loop by the pipeline series connection successively.
Above-mentioned carbon dioxide heat-pump double-temperature drinking machine, preferable scheme be, by on cold courage and hot courage thermocouple temperature sensor A, B being set respectively, and thermocouple temperature sensor A, B are connected with corresponding triple valve.So just can judge the opening direction of triple valve A, B, C, D, thereby realize the automatic conversion of different system circulation by detecting cold courage temperature (tL) and hot courage temperature (tR).
The beneficial effects of the utility model:
Double-temperature drinking machine of the present utility model in conjunction with forming a system, forms a CO 2 trans-critical heat pump water dispenser with carbon dioxide heat-pump and water dispenser, supplies hot and cold water simultaneously, bring into play the carbon dioxide heat-pump system environmental protection and energy-conservation aspect advantage.The attainable function of the utility model: can be in hot water cold water or airborne transfer of heat, thus feeding cold water and hot water simultaneously.
From the energy-conserving and environment-protective aspect,, very little to the influence of environment because (1) adopts the carbon dioxide heat-pump circulation; (2) the carbon dioxide heat-pump system can realize refrigeration and heat two kinds of functions, and is simple in structure; (3) exothermic temperature of CO 2 cross-critical heat pump cycle is higher, and has a sizable temperature glide (about 80~100 ℃), is fit to very much the heating to water, and 90 ℃ hot water can be provided; (4) heat pump cycle is the circulation that a kind of energy shifts, and heats the hot water of the same water yield, and energy consumption only is 1/4 of electrical heating and combustion gas heating.
Description of drawings
Further specify concrete structure of the present utility model below in conjunction with accompanying drawing 1:
Fig. 1 is the structure principle chart of carbon dioxide heat-pump double-temperature drinking machine of the present utility model.
The name of each critical piece is called:
1-compressor 2,5,7,10-triple valve A, B, C, the hot courage 4-of D 3-gas cooler
The cold courage 9-of 6-expansion valve 8-evaporimeter 11,12-thermocouple temperature sensor A, B
The specific embodiment
Embodiment 1
Carbon dioxide heat-pump double-temperature drinking machine described in the utility model, the method for its heating and refrigeration are by striding critical CO
2Gas cooler 4 in the heat pump circulating system and evaporimeter 9 add hot and cold courage 8 cooling to hot courage 3 respectively and realize supply hot water or cold water purpose.
Concrete structure as shown in Figure 1, the circulation of cooling water and the circulation of heat supply water of carbon dioxide heat-pump double-temperature drinking machine are made up of compressor 1, triple valve A2, hot courage 3 or gas cooler 4, triple valve B5, expansion valve 6, triple valve C7, cold courage 8 or evaporimeter 9, triple valve D10 successively, and form loop by the pipeline series connection.
Its operation principle is: carbon dioxide is compressed into the supercritical gas of HTHP in compressor 1, again by entering hot courage behind the triple valve B2 by the water cooling in the hot courage, simultaneously water is heated to the temperature of setting.Carbon dioxide becomes low-temp low-pressure liquid by expansion valve after flowing out hot courage, by entering cold courage evaporation heat absorption behind the triple valve C7, cools off the water in the cold courage then, and last carbon dioxide comes back to compressor.
Carbon dioxide heat-pump double-temperature drinking machine described in the utility model can be different according to the user demand, change by triple valve, keep the stable of system works, realize the supply of cold water and hot water.
