Abstract
The invention discloses a defrosting method for a heat-pump type air conditioner, which decides whether the defrosting operation mode, namely setting environment determination temperature t<1> and t<2> and three constants a, b and c, is carried out by combination of coil tube temperature T<z> of an outdoor heat exchanger, outdoor temperature T<h>, actual heating time H<y> and set heating time h<y>; under the following conditions, the unit starts the defrosting operation mode: 1. when T<h> is less than or equal to t<1> and more than or equal to t<2>, if the coil tube temperature T<z> of the outdoor heat exchanger meets the condition of T<z> less than a, T<h> plus c and H<y> larger than h<y> in a continuous M minutes, the unit starts to defrost; 2. when T<h> is less than t<2>, if the coil tube temperature T<z> of the outdoor heat exchanger meets the conditions of T<z> less than b, T<h> plus c and H<y> larger than h<y> in a continuous M minutes, the unit starts to defrost. The defrosting method has the advantages of shortening defrosting time, improving defrosting efficiency, leading to thorough defrosting and greatly improving heating efficiency.
Description
Technical field
The present invention relates to a kind of Defrost method of air conditioner heat-production pattern, specifically a kind of Defrost method of heat pump type air conditioner.
Background technology
The Defrost method of traditional heat pump type air conditioner generally is sensing chamber external heat exchanger middle part coil temperature and heating operation time, begins defrosting during less than setting value greater than setting value and middle part coil temperature when the heating operation time.This Defrost method must judge earlier whether compressor has moved an official hour continuously before unit enters defrosting, and this stipulated time is changeless.Under the low excessively situation of outdoor environment temperature, this Defrost method causes the frequent defrosting of unit easily and reduces heating efficiency; Simultaneously, under the big situation of outside humidity, because the existence of set time, in one-period, will make the full thick frost of outdoor heat exchanger knot, cause heating effect after this sharply to descend, and defrosting time is increased greatly, defrosting efficiency is low, and the halfway phenomenon that defrosts can appear, reduce heating efficiency greatly.
A kind of Defrost method of heat pump type air conditioner is disclosed on the website of State Intellectual Property Office, it relatively determines whether to defrost according to first temperature difference of interior conduit temperature and room temperature and second temperature difference and reference value, it has changed certain problem of time in traditional Defrost method, heating efficiency is increased, but this Defrost method is not owing to consider outdoor environment temperature, the time of absolute humidity and defrosting, can not be along with the frosting situation of outdoor heat converter is allocated automatically, so outdoor environment temperature be lower than 0 ℃ and humidity greater than 70 ℃ abominable situation under, it is short that it heats the time, defrosting time is long, frost can not remove clean, defrosting efficiency is lower, and its heating efficiency is still undesirable.
Also have, when the Defrost method of the heat pump type air conditioner of prior art entered defrosting at unit, indoor fan generally was out of service, and there was a large amount of liquid that returns in off-premises station when therefore defrosting was carried out, this kind situation will cause defrosting time to extend greatly, might cause the compressor liquid hammer if deal with improperly.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of and can shorten defrosting time, improves defrosting efficiency, makes defrosting thoroughly and increase substantially the heating and defrosting method of the heat pump type air conditioner of heating efficiency.
Technical solution of the present invention is that (heating) Defrost method of a kind of heat pump type air conditioner is provided:

Outdoor compressor stopped when unit entered the defrost operation pattern, N after second outdoor fan stop, four-way (commutation) valve commutation, compressor start, the heating of indoor set auxiliary electrical is opened, blower fan transfers low wind shelves automatically to, and stops operation in L minute in L minute according to opening.
The unit defrosting finishes to judge: outdoor heat exchanger middle part coil temperature T
z＞G ℃ or defrosting time Hc＞K minute, then defrosting finishes.
When the unit defrosting finished, indoor electrical auxiliary heater was closed, and indoor fan is closed, and outdoor compressor stops, and R is after second, and cross valve commutates, fan starting, compressor start.

The heating and defrosting method of heat pump type air conditioner of the present invention compared with prior art has following remarkable advantage and beneficial effect:
This Defrost method need not before unit enters defrosting to judge whether compressor has moved an official hour continuously, nor be subjected to changeless time-constrain, overcome traditional Defrost method under the low excessively situation of outdoor environment temperature, caused the frequent defrosting of unit easily and the defective of reduction heating efficiency; Also overcome traditional Defrost method simultaneously under the big situation of outside humidity, because the existence of set time, in one-period, will make the full thick frost of outdoor heat exchanger knot, and cause after this heating effect sharply descend,, defrosting time is increased greatly, defrosting efficiency is low,, the defective that defrosting does not reduce heating efficiency thoroughly, greatly appears.
The Defrost method of heat pump type air conditioner of the present invention utilizes the frosting situation of outdoor heat exchanger to concern that with outdoor environment temperature (outdoor environment temperature is low more, the easy more frosting of heat exchanger) multiple factors such as coil temperature decision content and outdoor environment temperature is connected, therefore the coil pipe frosting of outdoor heat exchanger can be accurately detected, make the middle part temperature of outdoor heat exchanger can more directly react unit frosting degree more accurately, guarantee that effectively unit can in time enter defrosting, has increased substantially the heating efficiency of unit.
The Defrost method of heat pump type air conditioner of the present invention has been taken all factors into consideration outdoor environment temperature, actual defrosting time, the actual multiple factors such as time that heat, dynamically adjust according to actual time and the actual defrosting time etc. of heating, promptly along with the frosting situation of outdoor heat converter is allocated automatically, Defrost method as heat pump type air conditioner of the present invention heated the time with dynamic adjustment of actual defrosting according to the actual time that heats, and then the minimizing defrosting time, guarantee the heating efficiency in the next one heats the cycle; And for example, the Defrost method of heat pump type air conditioner of the present invention is with outdoor heat exchanger middle part coil temperature T
zContinuous N minute satisfies T
z＜a T
h+ c and H
y＞h
y, as one of decision condition that enters the defrost operation pattern, prevent that effectively temperature sensor from gathering outdoor heat exchanger middle part coil pipe instantaneous temperature and causing the mistake of mistake defrosting, accomplish frostlessly not remove.So outdoor environment temperature be lower than 0 ℃ and humidity greater than 70 ℃ abominable situation under, also can reduce defrosting time, guarantee the heating efficiency in the next one heats the cycle, it heats, and the time is long relatively, and defrosting time is short relatively, the defrosting efficiency height, the Ex-all of frost energy, its heating efficiency is very good.
Also have, when the Defrost method of heat pump type air conditioner of the present invention enters defrosting at unit, utilize the electrical auxiliary heater heating of indoor set, make indoor fan be in out the running status of stopping in L minute L minute simultaneously, a lot of defrosting times (as shortening defrosting time 30%) can be shortened, and the liquid that returns of off-premises station can be greatly reduced.
