The specific embodiment: as shown in Figure 1, the auxiliary hot type Teat pump boiler of this combustion gas comprises the water source port one, water port 2, hot water storage tank 3 and heat exchanger 4, hot water storage tank 3 is provided with water tank water intake port 31 and water tank water outlet port 32, heat exchanger 4 is provided with heat exchanger water inlet port 41 and heat exchanger water outlet port 42, heat exchanger water outlet port 42 is communicated with water tank water intake port 31, simultaneously, it also comprises water source check valve 5, electric T-shaped valve 6, combustion gas heating unit 7, water circulating pump 8, the water inlet port 51 of water source check valve 5 is communicated with the water source port one, the water outlet port 52 of water source check valve 5 respectively with heat exchanger water inlet port 41, the water inlet port 81 of water circulating pump 8 is communicated with, the water outlet port 82 of water circulating pump 8 is communicated with first port 61 of electric T-shaped valve 6, second port 62 of electric T-shaped valve 6 is communicated with water tank water outlet port 32, the 3rd port 63 of electric T-shaped valve 6 is communicated with the water inlet port 71 of combustion gas heating unit 7, and the water outlet port 72 of combustion gas heating unit 7 is communicated with water port 2.
The auxiliary hot type Teat pump boiler of this combustion gas also comprises circulation check valve 9, and the water inlet port 91 of circulation check valve 9 is communicated with the water outlet port 72 of combustion gas heating unit 7, and the water outlet port 92 of circulation check valve 9 is communicated with water tank water outlet port 32.
The level height of water tank water outlet port 32 is greater than the level height of water tank water intake port 31 in the utility model, thereby can utilize hot and cold water to go up the physical effect of lower leaf automatically, improve Temperature Distribution in the hot water storage tank, improve water-heater efficiency, improve the heat storage capacity of hot water storage tank simultaneously.
The method of operation of the auxiliary hot type Teat pump boiler of this combustion gas is as follows:
Heat pump preheating operation pattern.The high-pressure gaseous refrigerant that compressor A discharges enters heat exchanger 4, cold-producing medium is condensed into liquid state after heat exchanger 4 release heat, inlet chamber external heat exchanger C after restricting element B decompression, the blower fan forced air flow is crossed outdoor heat exchanger C, air and cold-producing medium carry out the heat transmission by outdoor heat exchanger C, be vaporizated into gaseous state by liquid refrigerant after outdoor heat exchanger C absorbs heat, low-pressure gaseous refrigerant enters compressor A.Meanwhile, cold water enters heat exchanger 4 from the water source port one through water source check valve 5, and the heat that absorption refrigeration agent condensation process discharges enters hot water storage tank 3 from water tank water intake port 31 then.
The regenerative operation pattern.The high-pressure gaseous refrigerant that compressor A discharges enters heat exchanger 4, cold-producing medium is condensed into liquid state after heat exchanger 4 release heat, inlet chamber external heat exchanger C after restricting element B decompression, the blower fan forced air flow is crossed outdoor heat exchanger C, air and cold-producing medium carry out the heat transmission by outdoor heat exchanger C, be vaporizated into gaseous state by liquid refrigerant after outdoor heat exchanger C absorbs heat, low-pressure gaseous refrigerant enters compressor A.Meanwhile, the water that the temperature in hot water storage tank 3 bottoms is lower enters heat exchanger 4 from water tank water intake port 31, the heat that absorption refrigeration agent condensation process discharges, and 8 pressurizations enter electric T-shaped valve 6 through water circulating pump again.At this moment, first port 61 of electric T- shaped valve 6 and 62 conductings of second port, hot water directly enters hot water storage tank 3 from water tank water outlet port 32, so circulation, the hot water temperature reaches setting value in water tank; If the water temperature of hot water does not satisfy the accumulation of heat requirement, and satisfy combustion gas heating unit 7 and start service condition, then first port 61 of electric T- shaped valve 6 and 63 conductings of the 3rd port, hot water enters hot water storage tank 3 through circulation check valve 9 from water tank water outlet port 32 again by 7 heating of combustion gas heating unit.
The sterilization operational mode.The temperature of hot water is heated to more than 60 ℃, and the lasting regular hour, can realize disinfecting and sterilizing functions to hot water.Sterilization operational mode and regenerative operation pattern is basic identical, just sets the hot water temperature and should reach sterilisation temp more than 60 ℃, is incubated under sterilisation temp then, and makes temperature retention time satisfy the requirement of sterilizing.
Operational mode is heated in combustion gas separately.If the EAT of outdoor heat exchanger C does not allow operation of heat pump, cold water directly enters hot water storage tank 3 from water tank water intake port 31.When the 7 operation heating water outlets of needs combustion gas heating unit, second port 62 of electric T- shaped valve 6 and 63 conductings of the 3rd port, hot water enters combustion gas heating unit 7 from the water tank water outlet port 32 of hot water storage tank 3 through electric T-shaped valve 6, and after combustion gas heating unit 7 heated up, flow of hot water was to water port 2.For avoiding combustion gas heating unit 7 phenomenon to occur frequently starting in short-term, stopping, for stablizing the leaving water temperature of water port 2, after combustion gas heating unit 7 started, water circulating pump 8 started synchronously simultaneously.Specifically be, when the flow of water port 2 just often, second port 62 of electric T- shaped valve 6 and 63 conductings of the 3rd port, water circulating pump 8 moves with the low discharge state; When the flow of water port 2 reduces in short-term, first port 61 of electric T- shaped valve 6 and 63 conductings of the 3rd port, water circulating pump 8 is sent the lower water of hot water storage tank 3 temperature of lower into 7 heating of combustion gas heating unit with suitable flow, enters hot water storage tank 3 through circulation check valve 9 from water tank water outlet port 32 then.In addition, when the cold water that flows into from the water source port one when combustion gas heating unit 7 can satisfy instructions for use, first port 61 of electric T- shaped valve 6 and 63 conductings of the 3rd port, water circulating pump 8 is sent the lower water of hot water storage tank 3 temperature of lower into combustion gas heating unit 7 with suitable flow, directly flow to water port 2, at this moment, if regulate the flow of water circulating pump 8, part hot water hot water storage tank 3 tops be can also be entered through circulation check valve 9, thereby the water supply flow and the adjustment performance of water heater improved.
Because the auxiliary hot type Teat pump boiler of this combustion gas is provided with circulation check valve 9, thereby make the combustion gas heating unit 7 can be according to actual needs and participate in regenerative operation pattern, sterilization operational mode, combustion gas and heat operational mode separately, combustion gas heating unit 7 auxiliary heating functions be not fully exerted in Teat pump boiler.
The combustion gas heating unit 7 of the auxiliary hot type Teat pump boiler of this combustion gas is a gas heater.Combustion gas heating unit 7 is carried out suitable transformation, it is replaced with the auxiliary heating unit that adapts to use liquid fuel, solid fuel, electric power or other external heat source heat energy.Utilize liquid fuel or solid fuel to replace combustion gas, can improve the adaptive capacity of water heater variety classes fuel; Utilize electric power to replace fuel that auxiliary heat energy is provided, can simplify the structure and the operational management of auxiliary heating unit, reduce the manufacturing cost of water heater.
Outdoor heat exchanger C is carried out appropriate reconstruction, it is replaced with the low-temperature heat source heat exchanger, can make Teat pump boiler will utilize surrounding air other low-temperature heat source in addition, for example with the heat energy of water or other carrier transfer, make it be applicable to application scenario widely, for example, low-temperature water source waste heat recovery, surface water heat utilization etc.
