Description
Description
Technical field
The present invention relates to a kind of refrigerator and water heater double-duty plant, particularly one can be returned refrigerator waste heatReceive in order to heat domestic hot-water's refrigerator and hot water dual-purpose machine.
Background technology
Normal domestic use refrigerator is generally air cooling type refrigerator, and the used heat that compressor is discharged passes through air cooling heat radiatorIn surrounding air, its used heat is not utilized, and surrounding environment has been caused to thermal pollution; Simultaneously byCertain for fluid space in leaving to radiator, require refrigerator to leave approximately 10～20 centimetres, wall limit, wasteValuable living space. Common refrigerator power consumption about 1KWH～2KWH every day in the market, needs dischargeGo out the heat of 2KWH～4KWH, by these heat collection heating water that gets up, can solve people's major partHot water demand; A general refrigerator replaces with residual heat recovery type refrigerator and can save every year water heater power consumption 730KWH～1460KWH, energy-saving effect is fairly obvious. Thus, people can expect the used heat of refrigerator to collect naturallyHot water preparing gets up. Have many sections of inventions and utility model patent Literature Discussion collection refrigerator waste heat produce lifeThe power-saving technology of hot water. The Main of these patents is: by condenser for refrigerator (or comprising compressor)Directly be placed in hot water thermal insulating water tank, can well collect like this refrigerator waste heat, simultaneously can in the time that water temperature is lowTo improve the refrigeration of refrigerator, if but do not have other technical measures to match, when the water temperature liter in water tankGao Hou, can affect the refrigeration of refrigerator greatly, and the operating current of system is increased, and even causes compressorOverheated; If attemperater is arranged on to the top of former refrigerator, not with refrigerator one, need to increase by fourRefrigerant joint, has increased the probability of coolant leakage greatly, has brought difficulty to on-the-spot installation. Thus, afterwardsMany patent documentations in system, increased magnetic valve, temperature controller, threeway, two-bit triplet etc. to system waterWhen temperature rise, process, to ensure the reliability of system works. These patents, technical too complicated,Controlling unit is many, easily occurs various operation troubles, and product cost is high, is not easy to popularize.
Summary of the invention
The object of the invention is to propose a kind of cheap, stable and reliable for performance useless that refrigerator arranges that utilizeHeat is carried out the equipment of heating water---refrigerator hot water dual-purpose machine. It not only can realize the recovery of refrigerator waste heat,Can also lean on wall to place, save space, how high no matter the water temperature in attemperater has, canEnough ensure that refrigerator system normally freezes; Meanwhile, system have simple in structure, with low cost, easy for installation,The feature of stable and reliable operation.

Attemperater arranges auxiliary electrical heater pipe, and the opening of electric heating tube 10 is positioned at the bottom of water tank, vertically peaceDress, and around it, overlap one section of larger a little thermal sleeve 11, the root perforate of thermal sleeve, with convenientSupplement water inlet, the other end opening of thermal sleeve 11 and be positioned at the top of water tank;
Auxiliary electrical heater pipe also can be arranged on the top of water tank, and its installation site is lower than hot water outlet, levelInstall.
Auxiliary electrical heater pipe configuration temperature controller, the position of temperature controller temperature sensing hole is positioned at the middle part of water tank.
The upper lid of system compresses machine 1 is provided with compressor heat absorption cap 2, and described compressor heat absorption cap 2 is by inside and outsideTwo hemispherical corrosion resistant plates are welded, and in it, size and the compressor case of hemisphere match, at twoThe bottom of hemisphere, has a water pipe to be connected with the bottom of water-cooled condenser 4 by four-way, and its top is by insulationWater pipe is in parallel with the upper accepting water mouth of water-cooled condenser 4. Compressor heat absorption cap 2 is by steel wire rope and compressorBase tension, thus ensure there is good heat-transfer effect between compressor heat absorption cap 2 and compressor. CompressorThe outside of heat absorption cap 2 is surrounded by rubber-plastics material and makes muff.
The refrigerant circulation of the dual-purpose machine of a kind of refrigerator water heater of the present invention is as follows: compressor outlet → water-cooled is coldCondenser → device for drying and filtering → capillary → refrigerating chamber → compressor air suction mouth;
The water circulation of a kind of refrigerator hot water dual-purpose machine of the present invention is as follows: the cold water that is positioned at attemperater bottom→ straight-through tube connector 19 → water-cooled condenser → hot water is got back to the top of water tank; For ensureing normally entering of water circulationOK, the water level in attemperater must be higher than the upper surface of interior instlated tubular; When system real work, insulation waterWater in case non-homogeneous heating gradually, but make the water of water tank upper first heated, the water of its underpart will beCould heat after system circulation one time. Water level in water tank is on the low side, and running water entrance is provided with non-return safetyValve. After the water of water tank bottom is heated, system is fallen apart in air or and heat radiation by heat sink by heatIn the body of wall of plate close contact. There is no the parts such as water circulating pump due to system, system have production cost low,The advantage of stable and reliable operation, even temperature control electromagnetic breaks down in patent working example of the present invention, also onlyCan affect system in the refrigeration in summer, can make up by multiplex water, so the reliability of system isHigh.
Attemperater is made airtight pressure-bearing type, and inner bag adopts 304 stainless steels, middle filled polyurethane foaming,Shell all can with color steel or corrosion resistant plate.
