Description

High-temperature direct-heating water outlet heat pump unit

Technical Field

The utility model relates to a high temperature directly-heated goes out water heat pump set belongs to heat pump water heater technical field.

Background

The (water, sewage and air) source heat pump water heater is based on the reverse Carnot cycle principle, a unit takes a small amount of electric energy as a driving force, takes a refrigerant as a carrier, continuously absorbs low-grade heat energy (10-40 ℃) which is difficult to utilize (in water, sewage and air), converts the low-grade heat energy into high-grade heat energy (90 ℃), realizes the transfer of the low-temperature heat energy to the high-temperature heat energy, releases the high-grade heat energy into water to prepare hot water (42 ℃, up to 80 ℃), and conveys the hot water to a hot water tank or required equipment through a hot water supply pipeline to meet the hot water supply or heating requirements.

The (water, sewage and air) heat pump water heater has the advantages of high energy cleaning efficiency, low operation cost, environmental protection, safe operation, no need of guard, suitability for all bathing, breeding and slaughtering industries, and continuously expanded domestic market demands. However, the conventional heat pump water heater adopts 1 condenser, and 2 processes cannot solve the problems of low flow rate and small heat exchange temperature difference (difference between the condensing temperature in the condenser and the hot water outlet temperature), so that the conventional heat pump water heater has the disadvantages of high condensing pressure, large operating current, power consumption, energy saving and unsafety.

Disclosure of Invention

To the above problem, the to-be-solved technical problem of the utility model is to provide a high temperature directly goes out water heat pump set.

The utility model discloses a high temperature directly-heated goes out water heat pump set, it contains first condenser, second condenser, waterway system connecting pipe, freon system connecting pipe, hot water outlet, cold water inlet, freon air inlet, freon liquid outlet, pressure sensor, relief valve, sight glass and filter, first condenser be located the top of second condenser, and pass through waterway system connecting pipe and freon system connecting pipe between first condenser and the second condenser and connect, first condenser be provided with hot water outlet and top freon air inlet, the second condenser be provided with cold water inlet and bottom freon liquid outlet, bottom freon liquid outlet is connected with the filter that sets up below the second condenser, the filter be the dismantlement formula filter, first condenser and second condenser all be provided with the relief valve, the first condenser on be provided with pressure sensor, the second condenser on be provided with and look the liquid mirror.

Compared with the prior art, the beneficial effects of the utility model are that: this high temperature directly-heated goes out water heat pump set adopts two multi-process condensers to establish ties and increases water flow length, guarantee that the intraductal velocity of flow is in design range, reach the purpose that the difference between the condensation temperature in the condenser and the hot water play water temperature diminishes, it is big to realize the business turn over water difference in temperature, high temperature goes out water condensation pressure low, the operating current is little, high efficiency, energy-conservation, the safety purpose, a multi-process condenser system of sharing when two or more compressors are parallelly connected to be used, the condenser is established ties from top to bottom, it does not divide about, when stopping a compressor, the compressor of relative work has increased condenser heat transfer area, make full use of condenser heat transfer area during partial load, improve the energy efficiency ratio.

Reference numerals: the system comprises a first condenser 1, a second condenser 2, a water path connecting pipe 3, a hot water outlet 4, a cold water inlet 5, a pressure sensor 6, a safety valve 7, a liquid viewing mirror 8, a filter 9, a Freon system connecting pipe 10, an air inlet 11 and a Freon liquid outlet 12.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the following technical solutions are adopted in the present embodiment: it contains first condenser 1, second condenser 2, waterway system connecting pipe 3, freon system connecting pipe 10, hot water outlet 4, cold water inlet 5, freon air inlet 11, freon liquid outlet 12, pressure sensor 6, relief valve 7, sight glass 8 and filter 9, first condenser 1 be located the top of second condenser 2, and connect through waterway system connecting pipe 3 and freon system connecting pipe 10 between first condenser 1 and the second condenser 2, first condenser 1 be provided with hot water outlet 4 and top freon air inlet 11, second condenser 2 be provided with cold water inlet 5 and bottom freon liquid outlet 12, bottom freon liquid outlet 12 is connected with the filter 9 that sets up below second condenser 2, filter 9 be the dismantlement formula filter, first condenser 1 and second condenser 2 all be provided with relief valve 7, the first condenser 1 is provided with a pressure sensor 6, and the second condenser 2 is provided with a liquid sight glass 8.

The working principle of the heat pump unit is as follows: compressor is low pressure microthermal freon vapor compression becomes high pressure high temperature's steam, steam discharges into first condenser 1 through freon air inlet 11, carry for second condenser 2 through connecting pipe 10 behind first condenser 1, form microthermal freon liquid of high pressure in the bottom of second condenser 2, freon liquid gets into behind 9 filter filtration moisture content of filter and impurity through freon liquid outlet 12, then get into the evaporimeter through the expansion valve, evaporate in the evaporimeter, become low temperature low pressure steam, it compresses to get into the compressor induction port again, so circulate.

The compressor compression produces the heat that high pressure freon gas produced through condenser shell side condensation and takes away through the intraformational water of pipe, must reduce the heat transfer difference in temperature in order to raise the efficiency, in order to reach the effect, considers intraductal velocity of flow and heat transfer area, and the condenser is two, and every is the multithread, satisfies the requirement. And the purpose of adopting a condensing system is to increase the heat exchange area of other compressors when one compressor is stopped, so that the efficiency is improved.
