Description
Technical field
The present invention relates to refrigeration air-conditioner and control method thereof, relate in particular to the heat pump and the control method thereof of band hot water function.This heat pump comprises refrigerant side subsystem, water side sub, control system; The refrigerant side subsystem comprises compressor, part heat recovering heat exchanger, four-way change-over valve, source heat exchanger, expansion gear, air-conditioning side heat exchanger, regulates flowing to through four-way change-over valve.
Background technology
Existing heat pump can provide refrigeration, heat, and toward the heat source side release heat, absorbs heat from heat source side when heating during refrigeration, and Along with people's improves constantly what comfortableness required, and the use of heat pump more and more widely.Existing Teat pump boiler absorbs heat from heat source side, rejects heat to then in the water, and the client is provided hot water, belongs to energy-conservation cleaning products.The Along with people's growth in the living standard, the use amount of hot water strengthens; Along with the enhancing of environmental protection and energy saving consciousness, Teat pump boiler obtains use more and more widely.In order to satisfy the demand of freezing, heating, heat water, the simplest way is to purchase heat pump and Teat pump boiler, so relatively takies the place, and investment is also bigger simultaneously.Teat pump boiler adopts steam compression cycle; Cold-producing medium, compressor, condenser, evaporimeter have been used; This point is consistent basically with heat pump; Just guaranteeing that heat pump and Teat pump boiler can adopt same cold-producing medium, same compressor, same evaporimeter on the parts He on the principle, thereby practicing thrift some parts and the shared place of parts; In addition, need discharge used heat when heat pump freezes, Teat pump boiler all heats water throughout the year, if both unifications just can realize the recuperation of heat of freezing, hot water is free; Also have, cooling and warming is not all to need always, just can let heat pump, water heater integrated machine outside cooling and warming, heat water, and heat is accumulated.Based on above-mentioned feasibility analysis, heat pump manufacturer and Teat pump boiler manufacturer are all in the multiple purpose aeroplane group of developing oneself: freeze, heat, add hot water, the thermal source of employing can be air or water or soil or three's combination.
The first generation three alliance units are that portion of hot reclaims unit; Compressor outlet in source pump; The water-heater heat-exchanging device of connecting; Carrying out portion of hot reclaims; Hot water adopts the design method such as the Fig. 1 at water source as the byproduct of cooling and warming, and system comprises compressor A01, part heat recovering heat exchanger A02, four-way change-over valve A03, water source heat exchanger A04, cold-producing medium throttling arrangement A05, air-conditioning side water-to-water heat exchanger A07, gas-liquid separator A08, heat-exchanger pump A09, air-conditioning water pump A10, source water pump A11.Adopt design method such as Fig. 2 of air source, system comprises compressor B01, part heat recovering heat exchanger B02, four-way change-over valve B03, air source heat exchanger B04, cold-producing medium throttling arrangement B05, reservoir B06, air-conditioning side water-to-water heat exchanger B07, gas-liquid separator B08, heat-exchanger pump B09, air-conditioning water pump B10, blower fan B11.The method of direct expansion system such as Fig. 3, system comprise compressor C01, part heat recovering heat exchanger C02, four-way change-over valve C03, air source heat exchanger C04, cold-producing medium throttling arrangement C05, indoor coil C07, gas-liquid separator C08, heat-exchanger pump C09, indoor fan C10, outdoor fan C11.In refrigeration or water when heating, do not freeze or when heating, unit cannot heat water; In order to guarantee sufficient hot water supply, the user needs other hot water solution, such as gas heater, solar water heater, Teat pump boiler, electric heater; When its advantage is refrigeration; Hot water is free, and can reach very high temperature, about 65 degrees centigrade; When heating, the hot water temperature also can reach about 70 degrees centigrade.Chinese patent document number CN00109283.9 has announced relevant method for designing and control method.
The second generation three alliance units are full recuperation of heat units, have drawn the under-supply shortcoming of the first generation three alliance unit hot water, have increased hot water heat exchanger, have improved the system pipeline design, emerge the unit of a lot of forms; Wherein, the most simply be that full heat recovering heat exchanger follows closely after the compressor; During operation, can produce two high-pressure areas: hot water heat exchanger, condenser, its major defect are that the coolant injection amount is big, the refrigerant management is difficult, especially in air source heat pump system, very risky.In water resource system, problem is fewer, like Fig. 4; Heat recovering heat exchanger D02 follows closely after compressor D01, is thereafter condenser D03, is volume control device D04 afterwards; Be water side evaporimeter D05 then, this system is simple, and cooling and warming leans on the water route manual switching; Not only cost is low, and can guarantee all to be the adverse current state at any time, has made full use of heat exchanger performance.Because the cold-producing medium that water-to-water heat exchanger uses is few, this simple system is very practical.Also have heat recovering heat exchanger D02 is done with condenser D03 is in the same place, and such as a case tube heat exchanger, top is the recuperation of heat heat-exchanging tube bundle; The bottom is condensation tube bank, when needing full recuperation of heat, stops the condensation water route to get final product; In service, it is perhaps unnecessary can not cause cold-producing medium to lack.This method is fit to water resource system, is not suitable for the air source system.In the application of water resource system, be not suitable for the frequent occasion of switching of needs very much yet, under the pipe-connecting mode of refrigeration,, just do not produced the function of hot water if there is not the demand of refrigeration, some inconvenience needs a subsequent use thermal water source.
The third generation three alliance units also are full recuperation of heat units, more complicated to be hot water heat exchanger parallelly connected with condenser, evaporimeter, during operation, have only a heat exchanger to be in high pressure conditions; Two other heat exchanger, one is in idle state, and no cold-producing medium is flowed through, and is in low-pressure side, and cold-producing medium is flowed through, and another is in evaporating state, also is in low-pressure side, has cold-producing medium to flow through; Water resource system like Fig. 5, system comprises compressor E01, the first four-way change-over valve E02, the second four-way change-over valve E03, part heat recovering heat exchanger E04, water source heat exchanger E05, air-conditioning side water-to-water heat exchanger E06, the first cold-producing medium throttling arrangement E07a, the second cold-producing medium throttling arrangement E07b, gas-liquid separator E08, heat-exchanger pump E09, air-conditioning water pump E10, source water pump E11, check valve E12; The air source system like Fig. 6, system comprises compressor F01, the first four-way change-over valve F02, the second four-way change-over valve F03, air source heat exchanger F04, part heat recovering heat exchanger F05, air-conditioning side water-to-water heat exchanger F06, the first cold-producing medium throttling arrangement F07a, the second cold-producing medium throttling arrangement F07b, reservoir F08, gas-liquid separator F09, heat-exchanger pump F10, air-conditioning water pump F11, blower fan F12, check valve F13; Carry out the cold-producing medium switching-over through two four-way change-over valve E02 and E03 or F02 and F03, when heating water, compressor air-discharging is imported in the hot water heat exchanger through cross valve; Chinese patent document CN200720124373.5 discloses relevant design and running method.Can realize freezing recuperation of heat, singly heat water, freeze and heat, main problem still is that refrigerant managing is difficult, unit switches and is easy to generate a large amount of problems, causes the construction cycle long, the field failure rate height.
The 4th generations three the alliance unit also be full recuperation of heat unit, it has used for reference third generation pluses and minuses, has increased to heat water and the function that heats simultaneously.Like Fig. 7, system comprises compressor G01, the first magnetic valve G02a, the second magnetic valve G02b, four-way change-over valve G03, air source heat exchanger G04, part heat recovering heat exchanger G05, air-conditioning side water-to-water heat exchanger G06, the first cold-producing medium throttling arrangement G07a, the second cold-producing medium throttling arrangement G07b, reservoir G08, gas-liquid separator G09, heat-exchanger pump G10, air-conditioning water pump G11, blower fan G12, check valve G13; Announced its one step process just among the Chinese patent document CN200520047214.0, opened the first magnetic valve G02a and the second magnetic valve G02b, can realize heating simultaneously water and heat.But it still has the main shortcoming of third generation unit: cold-producing medium is difficult to management, the unit risk of handover is big, the construction cycle is long, fault rate is high, compressor reliability is not high.
When producing the domestic hot-water, also can run into the problem of chloride ion corrosion in the running water.Hot water heat exchanger generally all is that running water directly flows through, and purpose is in order to reduce heat transfer temperature difference, chlorion endlessly to be arranged in the running water, producing certain corrosiveness, so the place that contacts with running water utilizes copper pipe as far as possible.Adopt the heat exchanger of copper pipe at present, the one, case tube heat exchanger, the 2nd, double-tube heat exchanger.The case tube heat exchanger pressure drop is little, can be connected on after the compressor, in R22, R407C, R134a, R123 system, often can use, and cold is big; When adopting R410A as cold-producing medium, heat exchanger tube need increase wall thickness, and cost rises, so seldom use.The double-tube heat exchanger pressure drop is big, and cold is little, generally is not connected on after the compressor.Portion of hot reclaiming type unit adopts stainless steel plate type heat exchanger in addition, owing to receive chloride ion corrosion easily, so do not advise directly contacting with running water, can pass through middle heat exchange mode, and needing increases pump, can produce some losses simultaneously.Plate type heat exchanger is because pressure drop is little, compact, so in heat recovery system, often use.
