Abstract

The utility model relates to a water heater type dual-purpose air conditioner, which is an improvement for the existing air conditioners. Only on the basis of the air conditioner, a thermal insulating water tank is added and a water-cooling heat exchanger is added at the side of a compressor, and the utility model can realize the refrigeration and simultaneously can use the waste heat to produce the hot water. The utility model has the advantages of simple structure, convenient installation and operation, good energy saving effect, etc. The utility model is also suitable for the refrigerating equipment, such as the freezers, cold rooms, refrigerators, etc.

Description

Water heater type's air conditioner for both device

The utility model relates to a kind of air-conditioner, and particularly a kind of superheated vapor that utilizes the high pressure-temperature that compressor discharges heats water earlier before condensation and produces the air-conditioning of hot water, the air-conditioner of hot water two purpose.

One cover refrigerating plant is all arranged in the existing air-conditioner, cold-producing medium is compressed into the refrigerant gas of the superheated vapor of HTHP with compressor, cool off through condenser, the refrigerant liquid of warm high pressure in making it to become, after throttling mechanism throttlings such as capillary, heating power expansion valve, become the refrigerant liquid of low-temp low-pressure again, enter then that evaporimeter absorbs the external heat gasification and the refrigerant gas that becomes low-temp low-pressure, the refrigerant gas of the low-temp low-pressure after gasification enters the refrigerant gas that compressor is compressed into HTHP again, so circularly cooling.During work, what blow out at the condenser place with fan is hot blast, and what blow out at the evaporimeter place with fan is cold wind, by solenoid operated four-way valve, the function of indoor evaporator and outdoor condenser can be exchanged arbitrarily and air-conditioning become by refrigeration and heat.Because condenser is to discharge heat, especially in summer, environment temperature was original just very high, added that temperature that a large amount of heats that discharged by air-conditioning impel the city is higher and produced tropical island effect.

The purpose of this utility model is to make full use of the heat of air-conditioner to outdoor discharging, and the superheated vapor that designs a kind of HTHP with compressor output heats recirculated water earlier before entering condenser condenses and produces water heater type's air conditioner for both device of hot water.

Water heater type's air conditioner for both device of the present utility model, mainly form by air-conditioner, water-cooled heat exchanger and attemperater, water-cooled heat exchanger is installed near the interior compressor of air-conditioner, the air inlet pipe of described water-cooled heat exchanger is connected with the escape pipe of compressor, the escape pipe of water-cooled heat exchanger is connected with the high-pressure pipe of condenser or cross valve, and the delivery port of water-cooled heat exchanger is connected with the middle and lower part of attemperater with the water inlet water pipe.

Accompanying drawing 1 is the structural representation sketch of an embodiment of the present utility model.

Referring to accompanying drawing, 1 in the accompanying drawing is compressor, the 2nd, and the escape pipe of compressor, the 3rd, the air inlet pipe of compressor, the 4th, the air inlet pipe of water-cooled heat exchanger, the 5th, the escape pipe of water-cooled heat exchanger, the 6th, coil pipe, the 7th, insulation shell, the 8th, water inlet, the 9th, delivery port, the 10th, water inlet pipe, the 11st, outlet pipe, the 12nd, attemperater, the 13rd, cross valve, the 14th, condenser, the 15th, throttle mechanism, the 16th, evaporimeter.Wherein, water-cooled heat exchanger comprises insulation shell 7, coil pipe 6, water inlet 8 and delivery port 9, coil pipe 6 is contained in the insulation shell 7, the upper end of coil pipe 6 is the air inlet pipe 4 of water-cooled heat exchanger, the lower end of coil pipe 6 is the escape pipe 5 of water-cooled heat exchanger, the bottom of insulation shell 7 has water inlet 8, the top of insulation shell 7 has delivery port 9, in coil pipe 6 can be selected for use through being made into spirality or serpentine coil for the copper tube of 5-20MM or stainless steel tube, the volume of insulation shell 7 can be decided according near the space the compressor, for domestic air conditioning, the height of insulation shell is chosen as 100-300MM, the optional 50-200MM of internal diameter, the air inlet pipe 4 of water-cooled heat exchanger is connected with 2 solderings of compressor escape pipe or is threaded, the escape pipe 5 of water-cooled heat exchanger is connected with the high pressure admission mouth soldering of condenser or cross valve 13 or is threaded, and the delivery port 9 of water-cooled heat exchanger is connected with the middle and lower part of attemperater 12 with 10 with water inlet 8 difference water pipes 11.During work, the refrigerant gas that compressor is compressed into HTHP with the low-temperature low-pressure refrigerant gas that sucks is sent into the high pressure admission mouth of delivering to cross valve 13 behind the coil pipe 6 of water-cooled heat exchanger again from the escape pipe 2 of compressor, deliver to condenser 14 coolings again from the high pressure gas outlet of cross valve 13, become the refrigerant liquid of low-temp low-pressure again through throttle mechanism 15 step-downs, when evaporimeter 16 absorbing environmental temperature, flash at last refrigerant gas again and get back to from the air inlet pipe 3 of compressor and be compressed into the superheated vapor of HTHP again the compressor 1 and finish once circulation.When the superheated vapor of HTHP passes through the coil pipe of water-cooled heat exchanger, recirculated water heating to the coil pipe outer wall, water in the attemperater can be heated into wash and use hot water, the temperature that will enter the overheated gas of condenser again suitably reduces in advance, the heat that distributes through condenser is also just less again, reduced the problem that produces tropical island effect because of air-conditioning, simultaneously again because of twice cooling, make also corresponding the decreasing of temperature of compressor escape pipe place cold-producing medium, the noise and the power consumption of compressor can both be decreased, help improving the operating condition of compressor.When water receiving pipe 10 not and 11, air-conditioner also can operate as normal.When influencing air-conditioning work, water-cooled heat exchanger can be used as radiator cooler and uses when environment temperature is too high, makes air-conditioning can recover operate as normal.

The utility model only needs at attemperater of the basis of existing air-conditioner increase with at the air-conditioner compressor Water-cooled heat exchanger of other increase gets final product, and can produce hot water in refrigeration, and not increase energy consumption, and is real Existing dual-use has the advantages such as simple and reasonable, easy to install, good energy-conserving effect, is adapted at each Plant on the refrigeration plants such as refrigeration air-conditioner, heat pump type air conditioner, refrigerator, freezer and refrigerator and install and use.
