Abstract
The utility model relates to a separating cold and hot water machine set. An indoor heat exchanger with side water and refrigerant and a circulating water pump are arranged in the other independent box body which is arranged indoors, and therefore, the problem that the present cold and hot water machine set which is arranged outdoors is generally frozen when outdoor temperature is lower than 0 DEG C is solved.
Description
The utility model is a kind of vapor compression refrigeration device, is specially adapted to apartment and flats, villa and the hotel in a plurality of rooms.
The compressor of known its refrigeration system of hot and cold water unit, outdoor air--refrigerant heat exchanger, indoor water--refrigerant heat exchanger; And water circulating pump all places in the casing, usually place outdoor, the shortcoming of its existence is, when outdoor temperature is lower than 0 ℃, for anti-water-stopping system freezes, must take antifreezing measures or whole box body is placed indoor, must be with outdoor air--the cold-producing medium heat exchange winter cold air and the summer fever air drain into outdoorly, it can not provide life hot water simultaneously.
Task of the present utility model is a kind of convenient and practical, split-type cold and hot water supply unit that must be not antifreeze.
Another task of the present utility model provides a kind of convenient and practical, must be not antifreeze and can provide simultaneously life with hot water and energy-conservation split-type cold and hot water supply unit.
Following technical scheme can be finished the task that the utility model proposes.
The compressor of known its refrigeration system of hot and cold water unit, outdoor air--refrigerant heat exchanger, four-way change-over valve, indoor water--refrigerant heat exchanger and water circulating pump all place in the casing, indoor water--the refrigerant heat exchanger that is characterised in that of the present utility model, and water circulating pump places another independently in the casing, connects into a refrigeration system by the refrigeration tube connector between the two tanks.
The compressor of known its refrigeration system of hot and cold water unit, outdoor air--refrigerant heat exchanger, four-way change-over valve, indoor water--refrigerant heat exchanger and water circulating pump all places in the casing, a water--refrigerant heat exchanger is arranged on the pressure duct that is characterised in that between compressor and the four-way change-over valve of the present utility model, this heat exchanger and indoor water--refrigerant heat exchanger and water circulating pump places another independently in the casing, connects into a refrigeration system by the refrigeration tube connector between the two tanks.
Accompanying drawing has been described two embodiment of the present utility model, and the utility model is further described.
Accompanying drawing 1 is the refrigeration system and the water circuit system figure of split-type cold and hot water supply unit;
Accompanying drawing 2 is refrigeration system and water circuit system figure of the split-type cold and hot water supply unit of domestic hot-water supply.
Shown in Figure 1:
The 1-compressor; 2-four-way change-over valve 3-outdoor air--refrigerant heat exchanger; The two-way expansion valve of 4-; 5-indoor water--refrigerant heat exchanger; The 6-water circulating pump; The 7-stop valve that freezes; The 8-tube connector that freezes; 9-room fan coil; 10-water stop valve; 11-water tube connector; The A-casing; The B-casing
Split-type cold and hot water supply machine set compressor (1) shown in Figure 1, four-way change-over valve (2), outdoor air--refrigerant heat exchanger (3), two-way expansion valve (4) and refrigeration stop valve (7) place casing (A), casing (A) places outdoor usually, can land and also can be hung on the wall, because it does not have water circuit system, be not afraid of yet and freeze even outdoor temperature is lower than 0 ℃; Indoor water--refrigerant heat exchanger (5), water circulating pump (6) and water stop valve (10) place another casing (B), to have water circuit system to be that anti-freeze places usually indoor because of it, casing (B) links to each other with the refrigeration stop valve (7) of casing (A) by refrigeration tube connector (8), and each room fan coil (9) is connected with the water stop valve (10) of casing (B) by water tube connector (11).
Shown in Figure 2:
The 201-compressor; The 202-four-way change-over valve; 203-outdoor air--refrigerant heat exchanger; The two-way expansion valve of 204-; 205-indoor water--refrigerant heat exchanger; The 206-water circulating pump; The 207-stop valve that freezes; The 208-tube connector that freezes; 209-room fan coil; 210-water stop valve; 211-water tube connector; 212-water--refrigerant heat exchanger.
The split-type cold and hot water supply unit of domestic hot-water supply shown in Figure 2, compressor (201), four-way change-over valve (202), outdoor air--refrigerant heat exchanger (203), two-way expansion valve (204) and refrigeration stop valve (207) place casing (2A), because it does not have water circuit system, usually place outdoor, indoor water--refrigerant heat exchanger (205), water circulating pump (206), water--refrigerant heat exchanger (212) and water stop valve (210) place another casing (2B), indoor because of there being water circuit system to place usually, casing (2B) links to each other with the refrigeration stop valve (207) of casing (2A) by refrigeration tube connector (208), each room fan coil (209) is stopped (2B) by water tube connector (211) with case water stop valve (210) is connected water--and the two ends water stop valves (210) of refrigerant heat exchanger (212) link to each other with cold water pipe and hot-water line respectively.
The course of work of the split-type cold and hot water supply unit of domestic hot-water supply is when freezing summer, the high-temperature high-pressure refrigerant gas of compressed machine (201) compression enters water--and refrigerant heat exchanger (212) is condensed into highly pressurised liquid, making and enter water--the cold water heat absorption of refrigerant heat exchanger (212) becomes life and flows out with hot water, the cold-producing medium highly pressurised liquid is through four-way change-over valve (202) inlet chamber outside air--and refrigerant heat exchanger (203) continues cooling, become low-pressure low-temperature degree liquid by two-way expansion valve (204) throttling, through the inboard water of refrigeration stop valve (207) inlet chamber--refrigerant heat exchanger (205) evaporation heat absorption, the temperature of the water of flowing through is reduced, water at low temperature is delivered to the fan coil (209) in each room by water circulating pump (206), make the room cooling, evaporation back refrigerant gas is got back to compressor (201) by refrigeration stop valve (207) and four-way change-over valve (202) and is finished circulation.During winter heating, the high-temperature high-pressure refrigerant gas of compressed machine (201) compression enters water--refrigerant heat exchanger (212), when the needs domestic hot-water, the cold water temperature of flowing through is raise become hot water, condensation of refrigerant becomes liquid, by inboard water--the refrigerant heat exchanger (205) of four-way change-over valve (202) inlet chamber, this moment inlet chamber inboard water--the temperature of the water of refrigerant heat exchanger (205) can not raise, the blower fan of the fan coil in each room (209) does not start, therefore each room can not heat up, refrigerant liquid becomes low-temp low-pressure liquid through the reverse throttling of refrigeration stop valve (207) by two-way expansion valve (204), evaporation is got back to compressor (201) through four-way change-over valve (202) and is finished circulation in inlet chamber outside air--the refrigerant heat exchanger (203); When not needing the domestic hot-water, high-temperature high-pressure refrigerant gas is through water--refrigerant heat exchanger (212), inboard water--refrigerant heat exchanger (205) condensation of four-way change-over valve (202) inlet chamber, make the inboard water of inlet chamber--the water temperature rising of refrigerant heat exchanger (205), fan coil (209) by each room is delivered to each room with heat, and room temperature is raise.
