The energy-conservation cold-heat air-conditioning, water-heating device of the four seasons of meaning shown in the accompanying drawing 1 is in the operation of " cold air [M1] " mode, and electric heater (U) closes.This mode control scheme is: compressor (C), outdoor, internal fan (F1), (F2) leave, and four way solenoid valve (T) is in refrigerating state (outage attitude), and two reversing solenoid valves of gas circuit threeway (D) and electric heater (U) close; Opening/stopping of compressor (C), outdoor, internal fan (F1), (F2) also is controlled by indoor temperature sensor (K1) and indoor temperature setting value and indoor pipe temperature sensor (K2); Opening or stopping of wind direction air deflector (FD) arbitrarily determined by the user.Each heat exchanger working condition: the electric heater (U) of off-premises station air cooling heat exchanger (S) heat release, water-cooled coil pipe (A) and water cooling heat exchanger (B) heat exchange, indoor machine wind cold heat exchanger (V) heat absorption, water heater is not worked.Its function: refrigeration gas, the heat supply water of before not increasing power consumption, holding concurrently under the dike, the cold increase refrigerating capacity of available cold water, hot water economize on electricity 100%, refrigerating capacity increases by 10～20%, and economic benefits and social benefits are energy-conservation.Generally select this mode operation for use in summer.Its refrigerant circulation loop is: (the D of compressor (H) → two reversing solenoid valves of gas circuit threeway (D) 1→ D 2Path (the T of) → four way solenoid valve (T) 1→ T 2) → outdoor air cooling heat exchanger (making condenser uses) passage (S (S) 1→ S 2) coolant channel (B of " heat release " → check valve (P1) → water cooling heat exchanger (B) 1→ B 2) interior air cooling heat exchanger (the making evaporimeter uses) coolant channel (V (V) of " heat exchange " → filter (G) → capillary (J1) → check valve (P3) → interface (O1) → indoor cabinet 1→ V 2) " heat absorption " → interface (O 2Path (the T of four way solenoid valve (T) in the) → outdoor cabinet 4→ T 3) → receiver (Q) → compressor (C).At this state, water storage tank (H) is filled water earlier.Water in water cooling heat exchanger (B) is subjected to the heat density that adds of cold-producing medium condensate liquid to diminish and rise, and causes the self-loopa of water thus, and its closed circuit is: water storage tank (H) (h 1Water stream channel (the b of) → water route check valve (SP1) → tube connector (L1) → water cooling heat exchanger (B) 1→ b 2) → tube connector (L3) → water-cooled coil pipe (A) → tube connector (L2) → water storage tank (H) (h 2→ h 1); Open water intaking valve (W1) when taking hot water, running water enters water storage tank, and hot water flows out in the overflow pipe of box top; When the water tank bottom hot water temperature is also higher, can directly open outlet valve (W2) and take hot water, but when water storage tank (H) water level was lower than the height of recirculated water oral siphon, water system can not circulate, must replenish cold water.
When cold air [M1] mode is moved, principle or heat exchanging process that refrigeration gas, not only double not power consumption heat water but also increase refrigerating capacity are such: be warming up to about 50～80 ℃ after the compressed machine supercharging of refrigerant vapour, after refrigerant vapour flows to off-premises station air cooling heat exchanger (S) (making condenser uses), because fan (F1) blows outdoor air and flows through off-premises station air cooling heat exchanger (S), take away the heat of high temperature refrigerant, cold-producing medium becomes highly pressurised liquid from gaseous state, at this moment 10～14 ℃ of the high approximately outdoor environment temperatures of temperature ((about 45～50 ℃) of refrigerant liquid; After the hot high pressure refrigerant liquid flows to water cooling heat exchanger (B), because of its temperature is higher than water temperature in the water cooling heat exchanger (B), just the water in the water cooling heat exchanger (B) is heated, refrigerant liquid temperature reduces simultaneously, water in the water cooling heat exchanger (B) produces lift because of diminished by heat density, drives the water circulation; After capillary section (J1) throttling, become the low-pressure low-temperature liquid vapour mixture by cold excessively refrigerant liquid and enter indoor set air cooling heat exchanger (V) (making evaporimeter uses) by the high pressure refrigerant liquid, because indoor machine fan (F2) rotates, make outside the indoor air stream pervaporation organ pipe, air flowing and refrigerant of low temperature are carried out heat exchange, air cooling-down becomes cold air, refrigerant liquid flashes to gas, (Q) is inhaled into compressor again through receiver, finishes the circulation of cold-producing medium and the heat exchange of each circulation link.Wherein, the utility model proposes utilization is difficult to be heated domestic water by the heat that air is taken away from the condensation of refrigerant liquid that air-cooled condenser flows out, and utilize the cold of domestic water to cross the method for cold raising refrigerating capacity by making condensation of refrigerant liquid, have kill two birds with one stone, effect that economic benefits and social benefits are energy-conservation, this is a key point of the present invention, is the key technique of realizing this utility model key point and set up water cooling heat exchanger (B) after the air-cooled cold doubtful device of air-conditioner.The reasonability of this utility model key point is: optimum temperature is at 40～45 ℃ when directly using because of the domestic hot-water, the hot water of high-temperature needs blending cold water to use again, and the temperature of condensation of refrigerant liquid is greater than or equal to this temperature, possesses the temperature difference condition that adds hot tap-water; In addition from 1 ℃ of the every reduction of energy balance examination refrigerating fluid, it is about 0.8% that refrigerating capacity will increase, and as if reducing to 28 ℃ of calculating by it from 50 ℃ (design standard is 54 ℃), it can increase by 17.5% refrigerating capacity; In addition, because of the exchange heat that equates with the increase cold being arranged in hot water, making cold operation by the air-conditioner of 3.5 kilowatts of 1.1 kilowatts of refrigeratory capacitys of compression acc power calculates, its every operation can provide again and be equivalent to the heat that 600 watts of electricity add the device generation in one hour, move the hot water that 20 ℃ of 200 kg of water intensifications just can be provided in 8 hours every day, satisfy three-person household substantially and use.Mostly the scheme of many inventions and utility model is to increase water cooling heat exchanger between exhaust outlet of compressor and outdoor air cooling heat exchanger, though, these schemes have the little advantage of heat exchange area greatly because of cold-producing medium and water temperature difference and can obtain the hot water ability of higher temperature, but utilize it summer, then can not utilize the cold of cold water to cross the cold refrigerating capacity that increases by making cold-producing medium, just the single-action power save mode utilizes it to reduce Central Heating Providing again winter, is not ideal scheme; If condensation heat is used to heat water entirely, produce nearly 1 ton hot water daily, home-usely do not fall, cause the water waste; Therefore the economic benefits and social benefits characteristics of energy saving of cold-heat air-conditioning, water-heating three-purpose machine of the present utility model in summer is distinguished; In addition, compressor electric motor, valve block friction, gas compression etc. all make compressor heat up, and the intensification of compressor increases work done during compression consumption, and water cooling coil (A) makes it cooling, and the hot water temperature was raise, and has improved compressor efficiency again, also is that economic benefits and social benefits are energy-conservation; Water-cooled coil pipe (A) also has advantage simple for production.
