Description

Hybrid air-cooled handpiece Water Chilling Units
Technical field
The utility model belongs to field of air conditioning, particularly relates to a kind of hybrid air-cooled handpiece Water Chilling Units.
Background technology
At present, air-conditioning system will be discharged the heat suitable with refrigerating capacity according to conservation of energy principle in ambient atmosphere in refrigeration, so not only cause atmosphere used heat to pollute, but also can produce greenhouse effects.Meanwhile, people consume electric power, natural gas, fuel oil equal energy source again in addition and come heat hot water, as if do not have the loss of heat energy on the surface, yet in fact but be accompanied by the loss of entropy in the transfer process of heat energy form, undoubtedly be a kind of waste of the energy.Therefore, consume the least possible energy and provide comfortable environment, pay attention to energy-conservation and the environmental protection double benefit, become the research and development direction of current air-conditioning system for building.
For addressing the above problem, Granted publication number is: the Chinese utility model patent of CN 2548058Y disclosed a kind of " air-conditioning recuperation of heat unit " on April 30th, 2003, its technical scheme is: " be connected with heat recovering heat exchanger on the pipeline between compressor and the four-way change-over valve; and the delivery port of heat recovering heat exchanger is connected with a boiler, and the water inlet of heat recovering heat exchanger is connected with water inlet pipe." by heat recovering heat exchanger with the cooling of the superheated steam of high temperature, high pressure, be condensed into the liquid of high temperature, high pressure, simultaneously exhaust sensible heat and partial condensation latent heat are heated cold water, the hot water that heat is kept in the boiler, can provide lives uses hot water.
Though above-mentioned CN 2548058Y utility model patent technology is by setting up heat recovering heat exchanger, a large amount of condensation heat can be reclaimed, avoided the thermal pollution of air-conditioning system effectively to surrounding environment, but, this air-conditioning recuperation of heat unit only just can obtain the domestic hot-water under the operation of air conditioner situation, air-conditioning does not just have domestic hot-water's supply under the operation conditions, can't satisfy the demand of people to real-time domestic hot-water.Moreover this air-conditioning recuperation of heat unit can only be converted into the condensation heat of part hot water and realize that portion of hot reclaims, and heat recovery efficiency is low, is difficult to guarantee the normal domestic consumption of user, thereby makes that the use of air-conditioning recuperation of heat unit is limited.
Thereupon, the applicant for the heat recovery system that solves air-conditioning system under the situation that air-conditioning does not move, the problem that does not have the hot water supply, " a kind of recovery type heat air-cooled type air conditioning system entirely " proposed, include compressor, air side fins formula heat exchanger, cross valve, gas-liquid separator, throttle mechanism, heat recovering heat exchanger, liquid reservoir, air-conditioning side heat exchanger, the exhaust end of described compressor is provided with reversal valve, the utility model is connected with reversal valve and cross valve at the exhaust end of compressor, the superheated vapor that makes compressor discharge can all flow to heat recovering heat exchanger by reversal valve, also can perhaps get and all flow to air-conditioning side heat exchanger under the electric situation by all flowing to air side fins formula heat exchanger behind reversal valve and the cross valve at cross valve.This structure that realizes the refrigerant line switching by the mode that adopts reversal valve, cross valve and a plurality of magnetic valves, not only make cold-producing medium have multiple circulation style, and air-conditioning system is under the situation of operation and use hot water, realize the recovery of whole condensation heat, guaranteed heat recovery and reuse, improved the thermal efficiency, also strengthened simultaneously the hot water deliverability of air-conditioning system; Meanwhile, can be implemented in the function that air-conditioning can not provide hot water under the running status yet, can guarantee real-time hot water supply by control to the reversal valve in the refrigerant line, cross valve and a plurality of magnetic valves.
Although, this full the recovery type heat air-cooled type air conditioning system solved air-conditioning system of the prior art heat recovery system under the situation that air-conditioning does not move, do not have the problem of hot water supply.But,, from air, draw thermal source, so single recuperation of heat unit is to carry out air-conditioning heating mode and domestic hot-water's pattern simultaneously because heating with two kinds of mode of operations of domestic hot-water of this air-conditioning system is to use same heat-exchange system.
Therefore, at deficiency of the prior art, needing badly provides a kind of air-conditioning that can either guarantee under the operation conditions hot water supply not to be arranged, and can guarantee the hybrid air-cooled handpiece Water Chilling Units that air-conditioning winter heating and domestic hot-water use simultaneously again.

Full heat recovery type air cooling cold water machine pack module 41 heat workflow: heat start → 1S → water pump of air conditioner 31 prerun times of 31 operation → water pump of air conditioners (electric expansion valve of 60~180S) → first throttle mechanism 7 close 0 step → 1S → first magnetic valve 6 power on → 3S → the 3rd magnetic valve 9 powers on → 1S → first four-way change-over valve 4 powers on → electric expansion valve of 1S → reversal valve 3 power down → 5S → first blower fan high-speed cruising → 5S → first throttle mechanism 7 reaches the automatic adjusting of the automatic control → 60S of the electric expansion valve that heats initial opening → 10S → the first compressor 1 operation → 30S → first throttle mechanism 7 → first blower fan.
Common wind-cooled cold-water machine pack module 42 heat workflow: after receiving the enabled instruction of master controller → electric expansion valve of driving second four-way change-over valve, 17 → 1S → second blower fan high wind speed operation → 2S → second throttle mechanism 19 reaches the automatic adjusting of automatic control → 80S → second blower fan of the electric expansion valve of initial opening → 10S → unlatching second compressor 16 → 10S → second throttle mechanism 19.
During air-conditioning domestic hot-water mode operation: have only full recovery type heat wind-cooled cold-water machine pack module 41 operation domestic hot-water patterns this moment.When the hot water storage tank's 52 of hot water side temperature is provided with temperature-3 and spends less than hot water, all load unit operation.If when the hot water storage tank of hot water side 52 temperature were provided with temperature greater than hot water, unit all unloaded shutdown.A kind of shutdown or running status before the temperature difference keeps between-3 degree and 0 degree.Domestic hot-water's water pump 51 60S before unit operation brings into operation, and unit is all shut down back 30S and stopped.
Workflow under domestic hot-water's pattern of full heat recovery type air cooling cold water machine pack module 41: the electric expansion valve of hot water start → 1S → open domestic hot-water's water pump 51 → 30S → first throttle mechanism 7 close the 0 step → 1S → water pump 31 → 5S that turns on the aircondition → first magnetic valve 6 power on → 2S → the 4th magnetic valve 12 powers on → 2S → first four-way change-over valve 4 powers on → 1S → reversal valve 3 powers on → electric expansion valve of 5S → first blower fan high-speed cruising → 5S → first throttle mechanism 7 reaches the electric expansion valve that heats initial opening → 10S → the first compressor 1 operation → 30S → first throttle mechanism 7 to be regulated automatically → 60S → first blower fan regulates → 90S → pass water pump of air conditioner 31 automatically.
