problem ir decode and send

I have an air conditioner that a remote control that does not belong to decode recognized in the library irremote.h (nec then no, no, sony, etc), this means that the sketch

#define sprint Serial.print 
#define sprintln Serial.println
#include <IRremote.h>

#define IR_RCVR_PIN 11
IRrecv ir_receiver(IR_RCVR_PIN);
decode_results results;

void setup() {
    Serial.begin(9600);
    ir_receiver.enableIRIn(); // Start the receiver
}

void loop() {
   if (ir_receiver.decode(&results)) {
    dump(&results);
    ir_receiver.resume(); // Receive the next value
   }
}

int c = 1;

void dump(decode_results *results) {
   int count = results->rawlen;
   sprintln(c);
   c++;
   sprintln("For IR Scope: ");
   for (int i = 1; i < count; i++) {
       sprint("0x");
       sprint((unsigned int)results->rawbuf[i], HEX);
    sprint(" ");
   }

   sprintln("");
   sprintln("For Arduino sketch: ");
   sprint("unsigned int raw[");
   sprint(count, DEC);
   sprint("] = {");
   for (int i = 1; i < count; i++) {
       sprint("0x");
       sprint((unsigned int)results->rawbuf[i], HEX);
       sprint(",");
    }
    sprint("};");
    sprintln("");
    sprint("irsend.sendRaw(raw,");
    sprint(count, DEC);
    sprint(",38);");
    sprintln("");
    sprintln("");
}

I tried to change it raw, but nothing when I send the result obtained from this program the air conditioner does not turn on.
how should I do?
it may be that the problem are the khz (the program defaults to 38)? whether there is a program that tells me how to send khz
my remote control?
thanks beforehand
ps
my air conditioner is dell’haier
